title: Bulbar reticular unit activity during food ingestion in the cat.
abstract: During food ingestion in cats, the activity of single bulbar reticular neurons showed rhythmical spike bursts during the active jaw opening phase of mastication. By utilizing spike-triggered averaging techniques, certain reticular cells were strongly suggested to be inhibitory neurons projecting to jaw closer motoneurons. We propose that these bulbar reticular neurons participate in the central generation of masticatory jaw movements by rhythmically inhibiting jaw closer motoneurons during mastication.
