English: NbM lesioned animal (bottom right quadrant) in 4000 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 one trial. The trial starts in darkness. The "dim" light signal can be perceived in the video as a strip of light along the operant box floor. The presentation of the "bright" signal can be perceived as a flash of light. The chosen trial illustrates failed lever pressing where the forepaw is seen extended onto the lever but the bright light has not extinguished. We have chosen the longer signal duration to illustrate the rat attempting to retrieve a food pellet and returning to the lever for additional presses. Note: the additional lights that can be seen in the corners of the quadrants are infrared lights.
