title: The light-dark relation in maintained discharge of collicular neurons of the cat.
abstract: In dark-adapted state, neurons of superior colliculus showed higher frequency of maintained discharges than un light-adapted state. Among the active cells two types of interval histogram distributions were registered, uni- and bimodal.
