Obtaining PSTHτ transiency values in this study.

<p><b>(A).</b> Extracellular spike recordings (middle trace) were detected upon photopic light stimuli (bottom trace). Spikes were sorted offline by using the appropriate threshold line (dashed line) to determine spike timestamps (top trace). <b>(B).</b> To quantify transiency, peristimulus time histograms were created upon light response timestamps using the light onset as reference. PSTHτ values were obtained by determining the peak time (t_peak) and the peak amplitude (A1) and then A1*1/e was calculated and that gave the time constant itself (τ).
