Consciousness and amnesia after penetrating head injury: neurology and anatomy.

Among 342 men who survived severe penetrating brain wounds, only 15% had prolonged unconsciousness and 53% had no or momentary unconsciousness after injury, emphasizing the focal nature of these wounds. The left (or language-dominant) hemisphere was dominant for the "wakefulness" component of consciousness. The areas most associated with unconsciousness included the posterior limb of the left internal capsule, left basal forebrain, midbrain, and hypothalamus. Left dominance was not seen for posttraumatic amnesia after elimination of the wakefulness variable, suggesting that wakefulness may be linked to the role of the left hemisphere in verbal memory.

Kant's philosophy and its relationship with the thought of Bion and Money-Kyrle.

The authors assess the significance of the rediscovery of Kant's philosophy of mind, which in their view offers valuable insights into the basis of conscious and unconscious mental life, protomental structures and the organisation of the internal world. They draw attention to the importance of distinguishing between brain culture, as represented by the neurosciences in particular, and mind culture. The process of internalisation begun by Kant is stated to have been continued by present-day psychoanalysis, whose theories furnish some additional categories of the intellect. The ideas of Bion and Money-Kyrle are considered in the light of Kantian philosophy. The authors show how Kant's revolutionary shift from enquiring into things to enquiring into our mode of knowing them implied that the objects of experience were determined by the transcendental functions of the mind, seen as a priori elements. Space and time as pure intuitions, together with the categories of the intellect organised by the 'I think', were held by Kant to make knowledge possible. Noting that the unconscious is not to be equated with the Kantian noumenon, the authors contend that Kant's epistemology can help psychoanalysis today to reflect on the epistemic status of its own referent, the conscious and unconscious mind, as well as of its procedures and predicates.

The dream's navel between chaos and thought.

The authors begin by drawing attention to the problem of the transition from the biological to the psychic, noting that Freud himself, with his background in the neurosciences, grappled with it throughout his career. Certain recent paradigms more commonly applied to the natural sciences, such as in particular chaos and complexity theory, can in their view prove fruitful in psychoanalysis too, and it is shown how these notions are inherent in some of Freud's conceptions. The unconscious is stated to operate like a neural network, performing the kind of parallel processing used in the computing of highly complex situations, whereas the conscious mind is sequential. Dreams, in the authors' opinion, are organisers of the mind, imparting order to the turbulence of the underlying wishes and unconscious fantasies and structuring them through the dream work. Through dreams, the structured linearity of conscious thought can emerge out of the non-linear chaos of the drives. The dream's navel can be seen as the chaotic link, or interface, between the unconscious wish, which constitutes an attractor, and the conscious thought. The attractor may be visualised as having an hourglass or clepsydra shape, the narrow section being the dream's navel, and, being the same at any scale of observation, has the property of fractality.

Dream actors in the theatre of memory: their role in the psychoanalytic process.

The author notes that neuropsychological research has discovered the existence of two long-term memory systems, namely declarative or explicit memory, which is conscious and autobiographical, and non-declarative or implicit memory, which is neither conscious nor verbalisable. It is suggested that pre-verbal and pre-symbolic experience in the child's primary relations is stored in implicit memory, where it constitutes an unconscious nucleus of the self which is not repressed and which influences the person's affective, emotional, cognitive and sexual life even as an adult. In the analytic relationship this unconscious part can emerge essentially through certain modes of communication (tone of voice, rhythm and prosody of the voice, and structure and tempo of speech), which could be called the 'musical dimension' of the transference, and through dream representations. Besides work on the transference, the critical component of the therapeutic action of psychoanalysis is stated to consist in work on dreams as pictographic and symbolic representations of implicit pre-symbolic and pre-verbal experiences. A case history is presented in which dream interpretation allowed some of a patient's early unconscious, non-repressed experiences to be emotionally reconstructed and made thinkable even though they were not actually remembered.

Some psychoanalytic viewpoints on neuropsychiatric disorders in children.

The author addresses issues interfacing neuropsychiatry and psychoanalysis. He recommends psychoanalysis for children with Attention Deficit, Hyperactivity Disorder (ADHD) and Dysfunction in Attention and activity control, Motility control and Perception (DAMP). He attributes its low status in neuropsychiatric treatment recommendations partly to the fact that psychoanalysts do not always declare their specific field of investigation. The scientific community then assumes that psychoanalysis aims to comment on issues outside its field of investigation, e.g. on neurobiological aetiology. The community therefore fails to discern the psychoanalyst's specific task, to help the child express and work through his conscious and unconscious experiences. Clarity on the analyst's part will improve relations with the scientific community and facilitate a relevant comparison of treatment methods. Another reason for neuropsychiatry's negative attitude towards analysis is its unwillingness to accept that unconscious conflict influences behaviour. With theoretical and clinical arguments, the author argues that unconscious factors must be taken in to understand and to treat the child. Countertransference, often cumbersome with neuropsychiatric children, becomes easier to handle if the analyst is clear about his field of investigation. If he sees through simplistic formulations on aetiology, countertransference gets even more manageable. Psychoanalysis can result in considerable intellectual and emotional development, as illustrated by work with a latency boy with DAMP, autism and slight mental retardation. In his psychoanalytic theoretical framework of the case, the author unites ego-psychological formulations with a Bionian conceptualisation of the thought disturbance.

Sensory empathy and enactment.

The authors propose the concept of sensory empathy which emerges through contact between analyst and patient as they get in touch with an area concerning the primary bond. This area is not so much based on thoughts and fantasies as it is on physical sensations. Sensory empathy has to do with that instrument described by Freud as pertaining to the unconscious of any human, which enables one person to interpret unconscious communications of another person. The authors link this concept to that of enactment precisely because the latter concerns unconscious, early elements that fi nd in the act a fi rst meaningful expression. It involves both analyst and patient. In other words, the authors wish to emphasize the importance of the analytical process maintaining contact with that immense field of human interaction that can be defined as primary sensory area and which becomes intertwined with the evolution of affects. Clinical examples are provided to clarify these hypotheses.

Projective identification and consciousness alteration: a bridge between psychoanalysis and neuroscience?

The authors claim that projective identification in the process of analysis should be considered in a circumscribed manner and seen as a very specific type of communication between the patient and the analyst, characterised through a modality that is simultaneously active, unconscious and discrete. In other words, the patient actively, though unconsciously and discretely--that is, in specific moments of the analysis--brings about particular changes in the analysts state. From the analyst's side, the effect of this type of communication is a sudden change in his general state--a sense of passivity and coercion and a change in the state of consciousness. This altered consciousness can range from an almost automatic repetition of a relational script to a moderate or serious contraction of the field of attention to full-fledged changes in the analyst's sense of self. The authors propose the theory that this type of communication is, in fact, the expression of traumatic contents of experiences emerging from the non-declarative memory. These contents belong to a pre-symbolic and pre-representative area of the mind. They are made of inert fragments of psychic material that are felt rather than thought, which can thus be viewed as a kind of writing to be completed. These pieces of psychic material are the expression of traumatic experiences that in turn exercise a traumatic effect on the analyst, inducing an altered state of consciousness in him as well. Such material should be understood as belonging to an unrepressed unconscious. Restitution of these fragments to the patient in representable forms must take place gradually and without trying to accelerate the timing, in order to avoid the possibility that the restitution itself constitute an acting on the part of the analyst, which would thus be a traumatic response to the traumatic action of the analytic material.

+Gz acceleration loss of consciousness: time course of performance deficits with repeated experience.

OBJECTIVES: We examine the time course of performance recovery from gravity-induced loss of consciousness (GLOC) and evaluate the utility of exposing participants to repeated bouts of GLOC in promoting recovery time. BACKGROUND: A substantial number of accidents among fighter pilots have resulted from episodes of GLOC. U.S. Air Force doctrine holds that when pilots experience GLOC, impairment lasts for 24 s, in which there are 12 s of complete unconsciousness and 12 s of confusion. However, there is reason to suspect that performance efficiency associated with GLOC is degraded well before unconsciousness sets in and that more than 24 s are required for performance efficiency to return to baseline levels. Additionally, there is a belief that repeated exposure to GLOC will reduce recovery time. METHOD: Centrifuge simulators were used to induce GLOC in U.S. Air Force personnel with math and tracking tasks employed to emulate flight performance. Participants were tested once per week for 4 consecutive weeks. RESULTS: On average, performance deficits appeared 7.44 s prior to the onset of unconsciousness and persisted for 55.6 s following the GLOC event. Repeated exposure failed to moderate these results. CONCLUSION: The temporal course of performance deficits produced by GLOC far exceeds prior estimates. The problem is more serious than previously envisioned and it is not alleviated by repeated exposure to GLOC. APPLICATION: U.S. Air Force doctrine regarding the severity of GLOC and the utility of repeated exposure to this problem needs to be revised and these data incorporated into future aircraft auto recovery systems.

Subliminal stimulation research and its implications for psychoanalytic theory and treatment.

As a tribute to Freud's genius, he was able to recognize not only the importance of implicit unconscious learning but also the way it currently impacts on the patient in psychoanalytic therapy. He prevented the patient from viewing the analyst's facial expressions by placing the patient on the couch. In addition, the analyst was instructed not to say too much, to be neutral, nonjudgmental, and calmly reflective. Thus the patient's response to the facial expressions and voice tone of the analyst, even when subliminally perceived, were minimized. This may be even more significant in women, who seem to be more sensitive to nonverbal cues of emotional states. Ferenczi further elaborated on the importance of establishing a connective empathic relationship, using a kindly, soothing voice tone and being emotionally available. Sandler and Sandler (1994) also emphasized the importance of tolerance and acceptance when making interpretations. These clinical instructions diminish external threats to survival and thereby minimize the activation of the amygdala. These procedures in psychoanalytic treatment seem similar to a subliminal MIO message and to the subliminal exposure of a happy face, as mentioned above in the fMRI study by Whalen et al. (1998). The empathic responses of the therapist need to create a condition of safety. In turn, this decreases the patient's vigilance and defensiveness and allows for the emergence of unconscious material that can be worked through verbally and rectified by explicit memory. Another fascinating finding is that Freud (1914) became aware, in his paper on the repetition compulsion, that repressed traumatic and conflictual relationships are acted out behaviorally outside of conscious awareness. He then considered that the focus of analysis should be on analyzing the transference relationship, where this enactment was manifested. Brockman (1998) notes that modern empirical findings confirm Freud's clinical hypotheses regarding the repetition compulsion. Repressed traumatic emotional memories are encoded in the amygdala, and they are unconsciously enacted through behavior, especially in the transference. In summary, childhood and other traumatic memories become encoded in the amygdala and are later enacted and expressed behaviorally, especially in the transference relationship. Working through of the emotional trauma makes these implicit memories explicit and exposes them to adult judgment. When the therapist creates a condition of safety, old memories are reexperienced and detoxified. The memories are experienced as nonthreatening now, thus calming the amygdala and diminishing its activity. Biologically, new neural pathways from the cortex to the amygdala can be established, since the cortex is plastic. This process is slow and may account for the need to repeatedly work through in analysis old conflicted relationships that had threatened security and survival. As imaging techniques improve, we may soon be able to evaluate therapy outcomes scientifically by measuring these actual brain changes. We are on the threshold of establishing a scientific psychoanalysis, as empirical research is providing us with data that integrate the mind and the brain. Subliminal stimulation and brain imaging techniques provide us with important tools for developing an empirical base for psychoanalytic theory and treatment. These techniques were not available to Freud at the turn of the last century, and as we center the new millennium Freud's dream of psychoanalysis having a firm scientific foundation is becoming a reality.

Epidemiological findings in traumatic post-comatose unawareness.

We have examined the epidemiological background of 134 consecutive patients admitted to our centre who suffered from post-traumatic unconsciousness of over 1 month's duration. The incidence of such unconsciousness in Israel is estimated as 4 per 1,000,000, or one case in 410 hospitalizations for head trauma. The cause of trauma was a road accident in 69% of cases. Among victims, pedestrians and cyclists were more likely than four-wheeled vehicle drivers and their passengers to suffer from prolonged unconsciousness, from which they were less likely to recover.

Predictive value of an early Glasgow Outcome Scale score: 15-month score changes.

OBJECT: Does an early Glasgow Outcome Scale (GOS) assessment provide a reliable indicator of later outcome in a patient with traumatic brain injury (TBI)? The authors examined the utility of the GOS during early treatment as a predictor of outcome score 15 months postinjury by analyzing outcome score change in a group of patients with closed head injuries. METHODS: Glasgow Outcome Scale scores assessed within 3 months of injury (baseline) were compared with scores obtained at 15 months postinjury in 121 patients, primarily young military personnel. Score changes between baseline and 8 months postinjury were also studied in a subgroup of 72 patients. The impact of initial injury severity (determined by the duration of unconsciousness) on score change was also explored. The GOS scores at three time points within the 15-month period-baseline (within 3 months of injury), 8, and 15 months postinjury-were examined to ascertain when the maximal GOS score had been reached. CONCLUSIONS: Baseline GOS score was a reliable predictor of outcome in patients with an initial score of 5 (no disability) or 4 (mild disability), but not in patients with an initial score of 3 (severe disability). Patients who remained unconscious for more than 24 hours did not have significantly lower outcome scores than those who experienced loss of consciousness for less than 24 hours at 15 months postinjury. Interestingly, the duration of unconsciousness did not affect the likelihood of an improved score during the study period in patients with a GOS score of 3 or 4 at baseline. An updated evaluation conducted after the early phases of treatment is needed to provide a realistic prognosis of severe TBI.

The dialectically constituted/decentred subject of psychoanalysis. I. The Freudian subject.

Central among the irreducible elements that define a psychoanalytic understanding of man is Freud's conception of the subject, and yet this theme remained a largely implicit one in Freud's writing. The Freudian conception of the process by which the subject is constituted is fundamentally dialectical in nature and involves the notion that the subject is created and sustained (and at the same time decentred from itself) through the dialectical interplay of consciousness and unconsciousness. The contribution of psychoanalysis to a theory of subjectivity involves the formation of a concept of the subject in which neither consciousness nor unconsciousness holds a privileged position in relation to the other; the two coexist in a mutually creating, preserving and negating relationship to one another. The principle of presence-in-absence and absence-in-presence subtends the dialectical movement between conscious and unconscious dimensions of subjectivity.

[Motivation and psychoanalysis. A cross-road].

The concept of drive in psychoanalysis corresponds to the question of motivation. This is related to the psychoanalytical methodology that is founded up on a specific process of communication, the listening and the interpretation of subjectivity and its unconscious origins. This specificity explains why psychoanalytic psychology deals with attachment and aversion drive (on one side sexuality, broadly speaking, including infantile sexuality, and on the other side aggressivity and destructivity). In the unconscious part of the mind, these drives are materialized in fantasies, action representations, that impose themselves unconsciously upon the conscious mind and give rise to intrapsychic conflicts and to personality disorders that are treated by psychoanalysis.

[Field of consciousness and level of anticipation].

Man's main activity is to live his future, to shape it, to direct it and to constantly adapt it to circumstances. This phenomenon is "anticipation". As far as this perspective is adopted, the field of consciousness appears narrow but extremely changing. The unconscious does not exist in so far as a territory, a structure or an apparatus. Unconscious has not to be a substantive but only an adjective. Data of consciousness remain unconscious or subconscious during the main part of the time. Moreover, the subject may live his future at various levels, from a biologic one till transcendence and the data of consciousness much depend on this level. All pathologic states involve an impoverishment of the field of consciousness. This limitation is sometimes transitory, for example in psychomotor epilepsy and above all in various neuroses. The patient then undergoes a sudden "regressing dive", which may be very brief and remain unseen by observer. During the "dive", he can only anticipate rudimentary and maladjusted behaviours, neurotic symptoms. In conversion hysteria, the regression is more durable but partial. Psychotic limitation, the level of which is variable, remains as long as psychosis itself.

The preconscious and potential space.

Greenberg and Mitchell (1983) have suggested that the drive/structure model and the relational/structure model are mutually exclusive models of psychic life. We regard their contribution as an invaluable one, which makes explicit the fundamental divergences in psychoanalytic theory. We have examined a derivative tendency in the field, for drive and relational theorists alike, to present psychic life as a dichotomy between inner experience and outer experience. We see a tendency to equate the drive model with unconscious motivation, and to the primacy of internal experience. There seems to be an equivalent tendency to equate the relational model with conscious perception and motivation, and to the primacy of external experience. We are advocating, for drive and relational theorists alike, greater focus on the process of intermediation between internal and external experience in the psychic life of the individual. Within the context of the drive model, precedent for such a focus is found in Freud's conception of the preconscious, an essential third dimension whose function was to mediate between the conscious and the unconscious. Within the context of the relational model, Winnicott's notion of potential space serves as a bridge between interior experience and external reality in the life of the individual. Finally, we have argued that by constructing three-part models of psychic life, these theorists have laid the groundwork for a synthetic theory. Though for Freud the drive state is primary, and for Winnicott the relationship between the infant and its environment (mother) is primary, each theorist posits an intermediating zone that fulfills a similar function in the psychic life of the individual. Whether we choose to call that zone the preconscious or potential space, its function is to translate bidirectionally between the infinitely dimensioned realm of interior, or unconscious, experience and the time-and space-bound realm of external, or conscious, experience. By highlighting the parallel constructs, we are not claiming to have created a synthesis between the theories. Our claim is that the eventual road to synthesis appears to reside in the direction of a movement away from the dichotomy between the primacy of inner or outer experience, and toward the common meeting ground of the primacy of an intermediating function.

[The physiological criteria for the ability of stimulus recognition].

Neural mechanisms are considered of such unconscious psychic phenomena as subliminal perception of semantic stimuli, psychological defence, unaccountable emotions. The results are given of many years studies conducted by means of conditioned, electrophysiological and psychophysiological methods. The possibility is proved of semantic analysis of perception on unconscious level and formation of association with the help of unrealized emotionally significant words. At present it is possible to describe only few neural mechanisms of consciousness and unconsciousness; however, the development of contemporary psychophysiology allows to state that the analysis of this problem from scientific positions is the most correct way to learn the nature of the brain processes which are the basis of these complicated psychic phenomena.

Action theory within the structural view.

This paper presents a summary of a cohesive theme coursing through a group of selected papers written by the author over four decades. Purpose, intention, choice and decision are seen as firmly anchored within structural metapsychological theory. These constitute a cohesive and operative psychoanalytic theory of action, which Hartmann stated did not exist within psychoanalytic theory. The exposure and inclusion of this unconscious series of intrapsychic events obviates the need for many alternative theories which have been erected to give a place to these very functions. Unconscious decision, ego will and volition, the unconscious initiation and execution of action, operate during waking life, with as complete and complex secondary process mentation as secondary revision organizes the final shape and contents of a dream during sleep. These conceptual changes and advances have important psychosociolegal implications. Man not only does not know why he acts; he also does not always know that he acts. The mainstream itself is not monolithic and has also resisted the development of many of these advances. Factors responsible for this lag or block are adduced, which include anti-scientism or intellectuality, as well as, most importantly, a resistance to an increase of responsibility and accountability.
