Fig. 5.

Effects of nonstationary neuronal responses and variable measurement intervals on CP measurement. A: mean firing rate of a neuron with stationary spiking activity is displayed for 2 behavioral choices (black and gray lines) on left. Gray area indicates the interval for which neuronal responses are quantified to estimate CP. Distributions of neuronal responses for the 2 behavioral choices are shown on right in the corresponding colors with their means indicated by lines. B: response of a neuron with nonstationary spiking activity shown in the same format used in A. C: the same neuron in B to illustrate a situation in which the measurement interval varies in the offset between trials. Gray areas indicate examples of the measurement interval in 2 different trials. Right: distributions of neuronal response quantified by using such measurement intervals whose offset is random and uniformly distributed within a trial. To show the distributions in the limit, the length of the interval is assumed to be infinitesimally small.
