Extracellular recordings from mouse superior colliculus during the optokinetic reflex

This dataset contains extracellular recordings using Neuropixels 1.0 probes of neurons from the superior colliculus of mice viewing a drifting grating stimulus. The drifting grating stimulus included a "probe" phase every 0.5 to 1 s in which the contrast of the grating was briefly (50 ms) increased from 40% to 100%. The electrode was inserted at an extreme angle tangential to the medial-lateral axis of the brain so that most of the contacts were positioned in the zonal layer, the superficial gray layer, the optic layer, or the intermediate gray layer of the superior colliculus. The goal of this experiment was to understand how resetting saccades produced via the optokinetic reflex modulate visual responses in the superior colliculus.
