A neutral cue facilitates detection of a visual target by modulating attention

Twelve rats were trained to perform a two-choice visual detection task in which a right or left light was presented and the animáis were required to press the lever located under the illuminated light for a food reward. In seventy percent of the triáis the target light was preceded by presentation o...
