Psychiatric screening on a neurological ward.

Two psychiatric screening instruments, the Mini-Mental State (MMS), a test for cognitive disturbance, and the General Health Questionnaire (GHQ), were administered to 197 neurological in-patients. The results suggest a high rate of psychiatric disturbance. The highest rate of cognitive disturbance detected by the MMS was found in patients with Parkinson's disease. The highest rates of emotional disturbance indicated by GHQ scores were related to myasthenia gravis and multiple sclerosis. MMS scores but not GHQ scores were related to standard tests of cognition, the diagnosis of cerebral pathology, and CAT scan abnormality. The results also demonstrate that the GHQ does not adequately detect patients with cognitive impairment. It is concluded that in populations at high risk for cognitive impairment a tandem screening procedure utilizing tests for both cognitive and emotional disorders is needed.

Alteration of cortical orientation selectivity: importance of asymmetric input.

Rearing cats so that each of the two eyes sees stripes of a different orientation alters the orientation preference of visual cortex cells. This result can be obtained by rearing the cats in striped cylinders or with goggles attached to their faces, but a tighter control of orientation preference is achieved by the goggles.

Transient global amnesia: an extensive case report.

A case of transient global amnesia was studied in detail. Of note was a temporally extensive, although quite patchy, retrograde amnesia during the event for information recallable at other times. While a consolidation block can explain the anterograde amnesia in transient global amnesia, the profound retrograde amnesia requires an additional block in the retrieval of old, established memories.

Stimulation of albumin synthesis by amino acids following partial hepatectomy in the rat.

Albumin synthesis was measured, in vivo, in rats 16 hours after partial hepatectomy or after sham operation. When albumin synthesis was expressed in terms of whole body weight, partially hepatectomized rats synthesized significantly less than sham-operated rats. However, when albumin synthesis was expressed as a function of dry liver weight, the two groups synthesized similar amounts. Intragastric hyperalimentation with amino acids significantly increased albumin synthesis in partially hepatectomized rats.

Stereopsis in normal domestic cat, Siamese cat, and cat raised with alternating monocular occlusion.

Normal cats, cats raised with alternating monocular occluders, and Siamese cats were tested for stereoscopic vision using a shadow-casting technique that produced line stereograms. Human subjects were tested with the same apparatus. 1. Normal cats had stereoscopic vision, but AO and Siamese cats did not. 2. Normal AO cats, and Siamese cats all had equal visual activity (about 6 feet of arc) and all could make accurate judgments about the depth of real objects. 3. Normal cats could fuse crossed disparities as great as 50 feet of arc and uncrossed disparities as great as 30 feet of arc. 4. Normal cats could make stereoscopic discriminations with stimulus disparities greater than 1 degree, even though they could not fuse disparities of this magnitude. 5. Both the AO and the Siamese cats exhibited a convergent squint. 6. Human subjects viewing identical stimuli could not fuse stimuli having disparities greater than 10 feet, although they could make depth judgments for crossed disparities as great as 5 degrees. 7. These results imply that animals without binocular cells in area 17 do not have stereoscopic vision, but do not determine if disparity-selective cells in the visual cortex are responsible for stereopsis.
