WebMay 12, 2014 · If one were to plot a peri-event time histogram (PETH) of these responses aligned to the sound onset (as in figure 3 of ref. 1 ), neurons in V1 would show an increase in firing around the exit, when the light is delivered. Importantly, the time waited by the animals until they exit and receive the light will exhibit some variability. WebTo visualize and quantify the correlation between these external events and neural activity, a linear correlation technique called the peri-event or peri-stimulus time histogram is usually applied (Endres et al., 2008; Solari et al., 2024).
