Recordings from a Purkinje cell in the cerebellar nodulus of an anesthetized rabbit. Purkinje cell activity is modulated by sinusoidal vestibular stimulation about a longitudinal axis. The upper right hand corner indicates how the rabbit, in this case a doll, is stimulated. Note how the Purkinje cell discharges two kinds of action potentials. The low frequency action potential, termed a complex spike, discharges in phase with ipsilateral side down rotation. The high frequency action potential, termed a "simple spike," discharges in phase with contralateral side down rotation.
Microphotograph of a stellate cell recorded with a "loose patch" technique from the nodulus of the mouse cerebellum. The cell was labeled with neurobiotin applied through the recording micropipette.
