Autocorrelation Structure

Mean spike count autocorrelation values computed using 50-ms time bins in a 500-ms time window of the baseline as a function of time lags (mean ± SEM). The solid red line represents the exponential fit. The autocorrelation value at the shortest time lag of 50 ms shows refractory adaptation, and it has been excluded from the fit procedure. The intrinsic timescale obtained from the exponential fit is shown on the top right corner.
