Inhibitory tagging both speeds and strengthens saccade target selection in the superior colliculus during visual search.

An important aspect of efficient behavior during difficult, time-limited visual search is the efficient selection of sequential saccade targets. Recent findings suggest that inhibitory tagging may help to facilitate such efficient selection by modulating activity in the superior colliculus (SC). Here, we characterize and quantify the influence of this modulation and find that inhibitory tagging both speeds and strengthens saccade target selection at the level of individual SC neurons.
