Abstract: Available data regarding the use of the eyelid motor system as an experimental model for the study of neural control of spontaneous, reflex, and conditioned motor responses are presented. The profile, kinematics, and frequency-domain properties of the different types of eyelid response are described. The firing properties of the three types of motoneuron involved in eyelid responses are also explained. Finally, the putative role of cerebellar cortex and nuclei in the genesis and control of reflex and learned eyelid movements are discussed in relation with recent available data in alert behaving cats.
