✦ Synopsis

Just as for the forming of contrast in the optical system a lateral inhibition and facilitation of the individual sensory cell elements is necessary and evident, a temporal inhibition and facilitation must be assumed to exist in acoustic information processing. By means of interval histograms and joint interval histograms this paper shows examples of the temporal inhibition and facilitation in the specific acoustic nerve channels of a cat in the form of deviations from the pure statistical behavior of the activity of single neurons. In addition to the lack of certain spike intervals (called inhibition) and their increased appearance (designated as facilitation), particularly inhibition and facilitation of combinations of intervals are demonstrated. Finally, with regard to the appearance of diamond patterns in joint interval histograms, the possibility is discussed that some of individual acoustic nerve cells ought to be capable of analyzing harmonies.
