'Corollary discharge' neurons in cat superior colliculus.
A new type of saccade-related neuron has been encountered in the superior colliculus of the alert cat. These cells discharge with and during, but rarely before, saccades of all directions and amplitudes. Their response properties suggest that they may be conveying a corollary discharge to the superior colliculus, thus providing a signal which allows visual neurons to distinguish real movement from self-induced movement.
