[Neuronal populations in the posterior group of thalamic nuclei projecting into the amygdaloid complex and auditory cortex in the cat].
Location of neurons in posterior thalamic nuclei and neighbouring structures of the midbrain regions projecting to the amygdaloid complex and auditory cortex of cat was studied by the method of horseradish peroxidase. The main sources of these brain region projections to amygdaloid complex are peripeduncular , subparafascicular and suprageniculate nuclei and caudal division of the medial geniculate body. The cells of origin of projections to the auditory cortex are located in all medial geniculate nuclei and wide regions of the posterior thalamic group. Neuron pools projecting to the auditory cortex and amygdala exist in medial parts of the posterior thalamic nuclei. The role of posterior thalamic nuclei in transmission of auditory signals to amygdala is discussed.
