This study has led to the idea that the caudal portion inhibits the rostral portion of the reticular formation. [citation needed] Sagittal division reveals more morphological distinctions. The raphe nuclei form a ridge in the middle of the reticular formation, and, directly to its periphery, there is a division called the medial reticular ...
The oral pontine reticular nucleus, or rostral pontine reticular nucleus is one of the two components of the medial (efferent/motor) zone of the pontine reticular formation - the other being the caudal pontine reticular nucleus.
The paramedian pontine reticular formation (PMPRF) is involved in coordinating horizontal conjugate eye movements and saccades. To do so, besides projecting to the ibsilateral abducens nucleus, the PMPRF projects fibers through the MLF to the contralateral oculomotor nucleus (specifically, those of its motor neurons that innervate the medial rectus muscle).
There is also a population of catecholamine synthesizing neurons in the rostral dorsal raphe, and these cells appear to be relatively large. [ 3 ] The dorsal raphe nucleus is rich in pre-synaptic serotonin 5-HT 1A autoreceptors , and it's believed that the action of the selective serotonin reuptake inhibitors (SSRIs) in this region is ...
The tegmentum area includes various different structures, such as the rostral end of the reticular formation, several nuclei controlling eye movements, the periaqueductal gray matter, the red nucleus, the substantia nigra, and the ventral tegmental area. [3] The tegmentum is the location of several cranial nerve nuclei. The nuclei of CN III and ...
The rostral interstitial nucleus of medial longitudinal fasciculus (riMLF) is a collection of neurons in the medial longitudinal fasciculus in the midbrain. [1] It is responsible for mediating vertical conjugate eye movements (vertical gaze ) [ 1 ] [ 2 ] : 458.e1 and vertical saccades .
The tract is situated in the central portion of the reticular formation. [1] Structure ... (the rostral part of the solitary nucleus] ...
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 ]
