Identification of a rapid eye movement sleep window for learning of the win-shift radial arm maze task for male Sprague-Dawley rats.

This study identified a rapid eye movement sleep window (RSW) for the eight-arm win-shift radial arm maze (RAM) task. The RSW is defined as a period of time after training during which rapid eye movement (REM) sleep is necessary for efficient learning of a task. Rats were trained over a 15-day period on the win-shift RAM task.
