title: [Speech and perception in acoustic-mnestic aphasia].
abstract: In clinical practice of brain lesions one of the frequently encountered disorders is the so-called acoustico-mnestic form of temporal aphasia, which was first described by A.R. Luria. However, its nature and the mechansim of speech disorders in this form of aphasia are still not clear, despite the theortical and practical significance of this problem. The convened experiments have demonstrated that disorders of such forms of speech as nominating, repeating and understanding in acoustico-mnestic aphasia emerges from visual and acoustical perception and its complicated connections with speech. Disorders of nominative functions of speech are related mainly to defects in the visual sphere, disorders of repeating and partially understanding speech - with the narrowing of the volume of acoustical perception. A possible pathophysiological mechanism of such speech disorders may be a decrease in the brain activity which leads to a substitution of simultaneous processes of perception by successional ones.
