Neurons with complex visual properties in the superior colliculus of the macaque monkey

摘要

Single neurons were recorded from the superficial layers of the superior colliculus of immobilized monkeys (Macaca mulatta and Macaca irus). Two main functional types of neurons were found. The neurons of the first type (Type I neurons) responded well to simple stationary and moving stimuli such as spots, bars or slits of light. The latency of their response was 41 ± 6 ms. They were not directionally selective and responded to a large range of velocities
