Spontaneous firing patterns of identified spiny neurons in the rat
... In several instances differences in the rate and pattern of spontaneous activity in unidentified neostriatal neurons have been found to be related to other differences between these cells. For example, neurons with relatively high tonic spontaneous firing rates have been found to be most likely to s ...
