MUA in superior colliculus evoked by 10 Hz High and Low stimulus trains during different behavioral states. A–D, Spikes per stimulus for peak1 (A, D), peak2 (B, E) and peak3 (C, F) MUA responses evoked in superior colliculus by 10 Hz High and Low stimuli during either active exploration (left) or awake immobility (right) uncorrected (A–C) or corrected (D–F) by the spontaneous firing rate. Statistically significant (p < 0.05) differences between the groups within a behavioral state are marked by brackets, and significant differences between the two behavioral states are marked with asterisks in the right columns. The first (s1) and the last (s10) responses in the 10 Hz train (10 stimuli) are measured.
