Motilin, the gastroenteric hormone, decreases the discharge frequencies of action potentials and enhances IPSC amplitudes in a group of medial vestibular nuclear neurons by modulating the postsynaptic SK-channels and GABA-A receptors, respectively. These motilin actions are mediated through GPCR. Motilin may be co-released with GABA from floccular Purkinje cell axon terminals to affect the activity of postsynaptic medial vestibular neurons which relay the ocular reflexes.
