Multiunit bursts in rat pallidum during grooming and stereotyped jaw movements.
Extracellular recordings from the globus pallidus of awake, unrestrained rats showed a distinctive bursting activity during grooming behaviour and in periods of stereotyped jaw movements induced by amphetamine (3 or 5 mg/kg IP) or apomorphine (2 mg/kg SC). During stereotyped licking, there was one burst for each outward movement of the tongue. The bursts were shown to consist of several separate unit spikes firing so as to produce a fusiform envelope of amplitudes, suggesting an ordered recruitment of pallidal neurons related to licking.
