The paramedian pontine reticular formation (PPRF) is a subset of neurons of the oral and caudal pontine reticular nuclei. With the abducens nucleus it makes up the horizontal gaze centre. [1] It is situated in the pons adjacent to the abducens nucleus. [2]

Jul 24, 2023 · The mesencephalic reticular formation coordinates vertical gaze, the paramedian pontine reticular formation coordinates horizontal gaze, and the medullary pontine reticular formation coordinates head movements and gaze holding.

Aug 16, 2023 · The reticular (from the Latin reticulum, meaning net) formation is a far-reaching network of neurons extending from the spinal cord to the thalamus, with connections to the medulla oblongata, midbrain (mesencephalon), pons, and diencephalon.

The pontine reticular formation is positioned in the posterior part of pons, just in front of the fourth ventricle. It constitutes part of the extensive network of nerve cells and fibers in the brainstem. Find out more about the reticular formation here: reticular formation. Snell, R.S. (2010).

Studies of pontine reticular formation (PRF) units, usually performed in anesthetized, decerebrated, or immobilized preparations, have emphasized the sensory responses of these cells (1, 2). It has been repeatedly demonstrated, in experiments using both natural and electrical stimulation of sensory systems, that many of these neurons are ...

The paramedian pontine reticular formation, sometimes termed the ‘para-abducent nucleus’, is a centre for conjugate lateral gaze; if damaged there is inability to look to the side of the lesion (damage to an abducent nerve only affects lateral movement of one eye).

Jul 25, 2013 · Figure 1. (A) Seed regions of interest (ROI) are given on the pontine reticular formation (Red color). The target ROI is given on the intralaminar nuclei of the thalamus at the level of the commissural plane.

THE BRAINSTEM RETICULAR FORMATION . The pontine and medullary brainstem significantly contributes to cortical arousal, attention, sensory and motor facilitation and inhibition, and the orienting reaction.

The reticular formation is functionally divided into the ascending reticular activating system (ARAS), ascending pathways to the cerebral cortex, and the descending reticular system, descending pathways (reticulospinal tracts) to the spinal cord.

The mesencephalic reticular formation is primarily involved in the control of vertical gaze, the paramedian pontine reticular formation in horizontal gaze, and the medullary pontine reticular formation in head movements and gaze holding.
