Abstract
Eye position and the activity of 10 identified abducens motoneurons have been recorded during spontaneous eye movements in the alert cat. Total of 27 parameters were defined from recordings of eye position and velocity, from abducens motoneuron firing rate, and from a proposed double exponential model fitting motoneuron behavior during eye saccades. The principal component analysis was applied to these variables. Results suggest an independent coding of saccade duration and amplitude as well as confirm the validity of a double exponential as a description of motoneuron activity during the burst.
