[Conditions affecting the nature of the neuronal afterdischarges in the medial geniculate body of the cat].
Sound signals induced afterdischarges in 20-40% medial geniculate body units. Dorsal neurons of the MGB had afterdischarges in the form of an augmentation of the activity level after cessation of the stimulation. The ventral MGB neurons revealed rhythmic afterdischarges more often, their pattern depending on the parameters of stimuli. When moving sound source or synthetized speech-like sounds were used, the dorsal MGB neurons and numerous ventral neurons showed afterdischarges in the form of an augmentation of the activity level. After pure tone stimulation of the ventral MGB units, many of them revealed rhythmic afterdischarges. The level of anesthesia in the experiments seems to be important.
