Effect of blue light in the SNr of a SNrChR2 mouse (A) and green light in the SNr of a SNrArch mouse (B) on sensory-evoked multiunit responses recorded simultaneously in the superior colliculus (SC) and barrel cortex (BCx). Panels overlay whisker-evoked (WKR) responses in the absence (control) or presence of light in SNr. Field potential (FP) responses recorded in barrel cortex are also shown. Each panel is the mean of 30 trials. The light is on for 500 ms and whisker stimulation is presented 200 ms after light onset. Barrel cortex traces are broken to show the whisker-evoked cortical rebound. C, Population data showing the effect of light in the SNr on whisker-evoked responses in the superior colliculus and barrel cortex. Responses are measured during a 50 ms window after the whisker stimulus.
