Theoral pontine reticular nucleus, orrostral pontine reticular nucleus is one of the two components of the medial (efferent/motor) zone of thepontine reticular formation - the other being thecaudal pontine reticular nucleus. The efferents of these two structures together give rise to the medial (pontine)reticulospinal tract (which modulates the muscle tone of the trunk and limb musculature). A population of their neurons together also form theparamedian pontine reticular formation which is involved in the coordination of horizontal conjugate eye movements in response to head movements.[1]
This nucleus tapers rostrally to transition into the caudal mesencephalic reticular formation. It contains sporadic giant neurons.[citation needed]
It receives sensory and motor cortical afferents viacorticoreticular fibers.[1]
Different populations of the pontis oralis have displayed discharge patterns which coordinate with phasic movements to and fromparadoxical sleep. It is thus apparently involved in the mediation of changing to and fromREM sleep.[2]
