English: PPTg lesioned animal (top left 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 five trials to illustrate the full pattern of PPTg lesioned animals' behaviour (correctly performed trials interspersed with omissions). Each trial starts in darkness. The "dim" light signal 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. In the first and third trial the rat performs correctly, pressing the lever in response to the bright light signal. On the second and fifth trial the rat omits a response due to prolonged sniffing. On the fourth trial the rat omits a response due to prolonged houselight orientation. Note: the additional lights that can be seen in the corners of the quadrants are infrared lights.
