English: Sham lesioned animal (bottom right quadrant) in 1500 ms signal duration attention task. The signal light (houselight) is situated on the right of the quadrant and the lever and pellet receptacle on the left of the quadrant. The pellet receptacle is illuminated. The video runs for two trials. The first trial starts with the "dim" light signal that can be perceived as a strip of light along the operant box floor. The presentation of the "bright" signal can be perceived as a flash of light. There is a period of darkness before the second trial begins. In both trials the animal successfully presses the lever during the bright signal. Note: the additional lights that can be seen in the corners of the quadrants are infrared lights.
