[Activity of dopaminergic neurons of the substantia nigra: a functional significance?].
In this study, neuronal activity of dopamine (DA) containing neurons located in pars compacta of the substantia nigra is analysed by the use of the time interval histograms and autocorrelograms. These cells display a regular and rhythmic firing pattern which may possibly subserve the striatal regular spontaneous release of DA, and, then exert an homeostatic function within this part of the extrapyramidal system.
