[Neurobiological basis of human recognition of facial emotion].
In the review of modern data and ideas concerning the neurophysiological mechanisms and morphological foundations of the most essential communicative function of humans and monkeys, that of recognition of faces and their emotional expressions, the attention is focussed on its dynamic realization and structural provision. On the basis of literature data about hemodynamic and metabolic mapping of the brain the author analyses the role of different zones of the ventral and dorsal visual cortical pathway, the frontal neocortex and amigdala in the facial features processing, as well as the specificity of this processing at each level. Special attention is given to the module principle of the facial processing in the temporal cortex. The dynamic characteristics of facial recognition are discussed according to the electrical evoked response data in healthy and disease humans and monkeys. Modern evidences on the role of different brain structures in the generation of successive evoked response waves in connection with successive stages of facial processing are analyzed. The similarity and differences between mechanisms of recognition of faces and their emotional expression are also considered.
