Superior colliculus activity related to attention and to connotative stimulus meaning.
Single-and multi-unit activity was recorded from cells in the superior colliculus of two awake monkeys (Macaca fascicularis). 32.5% of 366 investigated units responded while the animals attentively gazed at visual stimuli. 50% of these neurons responded to all stimuli presented, including stationary and moving light bars, whereas the other neurons only responded to specific stimuli like faces or food. The responses of a part of these neurons depended on the connotative stimulus meaning.
