    • Abstract:
      Superior colliculus lesions generally result in a deficit in visual orienting described as sensory neglect. This observation was confirmed in this study: Rats with lesions did not orient to some stimuli that intact rats readily oriented to. However, rats with lesions did orient to stimuli that the intact rats treated as more salient. Also, when the less salient stimuli signaled aversive stimulation, the rats with lesions detected these stimuli. These findings suggest that superior colliculus lesions do not affect the detection of visual stimuli that have been neglected.
