Example Neurons

Example of two neurons with long and short intrinsic timescales. (A–C) Example neuron with long intrinsic timescale (τ = 420 ms) and response selectivity in the delay period. (A) Raster plot for right (red) and left (blue) trials aligned to the delay onset. Each dot indicates the occurrence of a spike. The average firing rates shown on top of the raster plot were computed using a 100-ms time window size stepped by 10 ms. (C) Mean autocorrelation values (mean ± SEM) as a function of time lag computed in the baseline period. The red line is the exponential fit. (B–D) Example neuron with short intrinsic timescale (τ = 67 ms) and not response selective in the delay period. (B) The same as in A. (D) The same as in C.
