From: Superior sensation: superior colliculus participation in rat vibrissa system
Response adaptation in the superior colliculus. PSTHs (A-D) show response characteristics of a single cell over a range of stimulation frequencies. Significant response magnitudes are indicated for each PSTH. E: Response magnitude decreases significantly as stimulation frequency increases (Friedman's test, P < 0.001). F: Phase-locking, measured as the coefficient of variation (CV) of the latency, also decreases significantly with increasing frequency stimulation (P = 0.007), but the CV remains relatively low even at high frequency.
