| Abstract: | Two populations of neostriatal neurons projecting into the globus pallidus and two neuron populations projecting into the substantia nigra were identified by antidromic testing in acute experiments on immobilized rats. Statistical analysis showed that the firing patterns of the identified output neurons were of either the grouped or single type. Cross-correlation analysis of the spontaneous activity of two neurons, one projecting into the substantia nigra, the other into the globus pallidus, showed that activity of the second neuron was inhibited for 300–400 msec after spike generation by the first neuron.Institute of Biological Physics, Academy of Sciences of the USSR, Pushchino-on-Oka.
