Schematic of the aperture-width discrimination task. On each correct trial, the distance between 2 retractable bars is set to a narrow or wide value, the main door opens, the rat enters the stimulus chamber, and samples the aperture with its facial whiskers and retreats to the left reward port if the aperture was narrow or the right reward port if the aperture was wide.
