A digital display of neuronal average firing frequencies.
A digital instrument is described which displays on a three-digit, seven-segment display the average firing frequency of a neuron. Averaging is done over essentially consecutive timing intervals of 1, 2, 5, 10, 20, or 50 s. Provision is made for overflow indication and for manual resetting. The design is simple, economical in the number of integrated circuits used, and may be adapted for measuring the average frequency of occurrence of events other than neuronal firing.
