Responses of the population of MGB neurons across stimulation conditions.

<p>Averaged post-stimulus time histograms (Bin duration: 3 ms) for the entire population of MGB neurons across the different conditions tested (<i>Δf</i> and SOA) for the 90/10% probability condition. The mean firing rate elicited by both stimuli (standard, blue lines; deviant, red lines) decreased directly with SOA (SOA = 2000, 500, 250 and 125 ms; from first to fourth rows, respectively), for the different <i>Δfs</i> tested (<i>Δf</i> = 0.37, 0.10 and 0.04; from first to third columns, respectively). Numbers in each plot indicate the number of neurons for each condition. Black horizontal lines under the PSTHs of the bottom row indicate the duration of the stimulus (75 ms).
