[Deviations of spontaneous firing in the cochlear nucleus of the frog from the renewal point process].
The analysis of statistical characteristics of spontaneous activity (distribution of interpulse intervals, hazard function, autocorrelation function, autocorrelation function for a process with shifted intervals, interdependence between adjoining intervals) for 123 units located in the cochlear nucleus of the frog has been performed. In the majority of cells, this activity was distinct from the poissonic process, and in some cases firing periodicity was noticed. Besides, deviations of the spontaneous activity from the renewal process were usually observed. A reliable positive correlation of interpulse intervals was typical for the majority of the units, though in some cases a negative correlation of short adjoining intervals was revealed. The data indicate the occurrence of effects of memory in the activity of single units of the acoustical system.
