[Effect of interruption of afferent inputs on the background activity and nature of neuronal interconnections in the neostriatum of the cat].
The influence of afferent inputs disruption on distribution of various types of background activity (its mean frequency, distribution of minimal and maximal interspike intervals and character of neuronal interconnection in the neostriatum) was studied in acute experiments on rats. It was shown that the presence of grouped type of the background activity depends on the activity of the cortical input. The thalamic input makes the background activity less organized. The activity of the cortical input is also responsible for the presence of a positive symmetrical maximum in the plot of the interconnection function of neurons with a grouped type of the background activity.
