Intrinsic processing in the mammalian superior colliculus

Curr Opin Neurobiol. 2002 Dec;12(6):668-77. doi: 10.1016/s0959-4388(02)00387-2.


The mammalian superior colliculus receives visual inputs from the retina and primary visual cortex in its superficial layers and sends descending motor commands from its deeper layers. It is now becoming clear that a connection exists between these layers, but the signal transmission through it is not robust. The induction of burst discharges in the deeper layer neurons by direct visual inputs from the superficial layers may lead to 'express' saccadic eye movements with extremely short reaction times in behaving animals.
