title: [Clinical features of focal brain lesions in the left-handed and ambidextrous].
abstract: On the basis of a study of 31 patients who demonstrated deviations from dextrality (Simistrals and ambidextrals) the authors describe some traits of the nervous and mental changes in focal brain lesions. There are insignificant correlations between the character of nervous and mental changes and the side of a brain lesion. The study demonstrated a wide variability of the clinical symptomatology, a peculiarity of each neurological and psychopathological phenomenon, distinguishing them from similar changes in dextrals. The studied contingent revealed prevalence of a disturbed sensory cognition in the clinical picture; the presence of special phenomena which most likely are not seen in dextrals and which are also related to a pathology of sensory cognition. It is being assumed that these clinical traits may testify to an insufficiency of speech lateralization in sinistrals and that an insufficient speech lateralization is accompanied by other than in dextrals organization of sensory processes.
