The reticular formation is a set of interconnected nuclei in the ... The thalamic pathway consists primarily of cholinergic neurons in the pontine tegmentum, ...
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 ...
Along with the oral pontine reticular nucleus, the midbrain reticular formation projects to the gigantocellular reticular nucleus. The midbrain reticular formation is the point at which the different algedonic signals come together, ensuring that the organism is aware of potential threats. [2]
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).
The central tegmental tract is a tract that carries ascending and descending fibers, situated in the midbrain tegmentum, and the pontine tegmentum. The tract is situated in the central portion of the reticular formation. [1]
The reticulotegmental nucleus, tegmental pontine reticular nucleus (or pontine reticular nucleus of the tegmentum) is an area within the floor of the pons, in the brain stem. This area is known to affect the cerebellum with its axonal projections.
The pontine tegmentum, or dorsal pons, is the dorsal part of the pons located within the brainstem. The ventral part or ventral pons is known as the basilar part of the pons , or basilar pons. Along with the dorsal surface of the medulla oblongata , it forms part of the rhomboid fossa – the floor of the fourth ventricle .
The main bulk of the tegmentum contains a complex synaptic network of neurons, primarily involved in homeostasis and reflex actions. It includes portions of the reticular formation. A number of distinct nerve tracts between other parts of the brain pass through it.
