The authors present their anatomo-clinical observation of amnesic syndrome occurring with brain tumoral infiltration. On the clinical level, the disorder is characterized by a memory encoding deficit. Anatomical examination shows a bilateral lesion of the mamillary bodies.
In all clinics we are faced with questions about certain aspects of cerebral dominance. We consider first the problem of recognition of faces where the right hemisphere plays a leading role. However, the disorders manifesting that function appear only bilateral lesions. This suggests that the left hemisphere participates in this process. The reception of language raises a problem which is analogous with the preceding: we propose the participation of both hemispheres in this activity: the left hemisphere is dominant in the analysis of phonemes and syntax, the right hemisphere seems implicated above all in the processing of prosodic aspects--in particular intonations and individual features of the voice.
Neurological complications of vertebral angiography are described with particular emphasis on memory and visual deficits. The material consists of 21 instances of such complications out of a total of 832 vertebral angiographies. A brief account is given of the posterior cerebral artery territory, which makes it possible to establish anatomo-clinical correlations. The pathogeny of the disorder is discussed.

Up-to-date views on the various types of infantile hydorcephalus are exposed from a practical neurosurgical point of view. The neuroradiological procedures are divided in 3 groups: the neuroradioisotopes, the angiographies and the pneumographies. They are described and analyzed. Indicators and possibilities are outlined. Their complementary value is stressed.

The observation of a crossed aphasia is presented in a right handed man. These troubles of the language appeared, following an anterior right temporal lobectomy for ablation of an oligodendroglioma. They are in accordance with the classic data of the litterature as much as by their clinical features than by their evolution.
Observation of a traumatic aphasia in a young man. After a coma and a period of mental confusion, language difficulties are limited, during a few weeks, to a severe global deficit in reading and naming. Meanwhile objects and pictures are perfectly recognized and the meaning of some words can be understood correctly. The commentary is made with reference to previous reports of similar case histories. Clinical and neuropsychological data suggest a focal lesion in the left temporal lobe, probably on the 2nd and the 3rd gyri.

The history and classification of the various types of hydrocephalus are outlined and the mechanisms as well as causes of infantile hydorcephalus are discussed. Acoording to aetiology the possible operative treatments are described and special mention is made of ventriculocardiac shunting with its indications, advantages and complications. Finally, the results that may be expected from operative treatment of infantile hydrocephalus are studied and the neuropsychological aspect is emphasized.
