Relevance of a neutral cue in a two-choice detection task in the rat

Relevance of a neutral cue for performance in a two-choice visuospatial detection task was examined. Nine rats were trained, 5 with short intertrial interval (ITI) and 4 with long ITI, to detect a target (lateral lights) presented after a neutral-cue (central light). The removal of the neutral-cue d...
