Neurons in the lateral geniculate nucleus of the monkey discharge impulses periodically under conditions of both dark and light adaptation. Brief intensity changes in one direction produce decreases in firing rate roughly proportional to the logarithm of the intensity; intensity changes in the other direction produce corresponding increases in firing in the same neuron.
