Irregularity in neocortical spike trains: Influence of measurement factors and another method of estimation

Chelvanayagam, D; Vidyasagar, T R

Description

Irregularity in the interspike interval is a common phenomenon especially in the neocortex. A measure of this random variation in the spacing between neuronal spikes is usually obtained with the coefficient of variation CV (standard deviation/mean interspike interval). In excitable cells, the standard deviation in the interspike interval can be large and the mean firing rate often fluctuates. As a result, there can be substantial variability in the value of the CV computed for the same spike...[Show more]
