Abstract

A possibility of parametric elimination of the visual component from the activity of the cat superior colliculus was sought for. Form a known population distribution of spike density, trial data simulating the transient visual response of the cat superior colliculrs were derived. The onset and the peak times of the visual activity were determined with 4 methods of spike density estimation: time histogram, inverse interspike-interval histogram, fixed and adaptive kernel estimation. The results were compared and applied to 178 trial data obtained with the chronic recording from the deep layers of the cat superior colliculus. The possibility of obtaining the activity component related with saccadic eye movements without behavioral task is discussed.
