[Cortical evoked potentials in children with lesions at different levels of the brain stem].
Analysis was made of EPs in the occipital and central cortical areas of injured rhombencephalic and basal diencephalic parts of the brainstem. Localization of the pathological focus in the rhombencephalon brought about facilitation of the EP as expressed in stability of its forms in different subjects, increased amplitude and distinctness of early components in the occipital projection area. When the basal diencephalic structures are injured the EPs are reduced. The most affected in the occipital area are the early waves, and in the associative area, the late components of response. The results so obtained help to elucidate the role of the brainstem structures in the EP genesis.
