abstract：:Several neurophysiological studies have highlighted the role of the midbrain periaqueductal gray matter (PAG) in the initiation of vocalization in various animal species, from frogs to primates. With regard to humans, only two cases of complete mutism following a lesion to the PAG have been reported so far. This artic...

abstract：:Blockade of L-type Ca2+ channels results in a decrease in firing frequency of neostriatal neurons. In contrast, N- and P/Q-types of Ca2+ channel cooperate to tune firing pattern, since both of these channel types have to be blocked to enhance firing frequency. Parameters of the intensity-frequency plot were differenti...
