The term "reticular formation" was coined in the late 19th century by Otto Deiters, coinciding with Ramon y Cajal's neuron doctrine. Allan Hobson states in his book The Reticular Formation Revisited that the name is an etymological vestige from the fallen era of the aggregate field theory in the neural sciences.
The reticular formation is a region in the brainstem that is involved in mediating arousal and consciousness. The limbic system is involved in mediating emotion, behavior, motivation, and long-term memory. Extraversion (E) – degree to which people are outgoing and are interactive with people, which is mediated by the activation of the ...
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 ...
Reticular formation: This is a large area in the midbrain that is involved in various important functions of the midbrain. In particular, it contains lower motor neurons, is involved in the pain desensitization pathway, is involved in the arousal and consciousness systems, and contains the locus coeruleus , which is involved in intensive ...
reticular formation (mediates autonomic responses) [3] [5] parasympathetic preganglionic neurons (for autonomic responses) [3] central nucleus of the amygdala [10] parabrachial area [10] locus coeruleus [10] dorsal raphe nucleus [10] solitariospinal tract → upper levels of spinal cord [5] other visceral motor or respiratory centers [10]
The reticular formation in turn conveys the tract to: [1] [page needed] (bilaterally via reticulothalamic fibers) thalamus - in turn projects to the cerebral cortex to mediate the conscious perception of noxious stimuli. via central tegmental tract → intralaminar nuclei of thalamus (these are considered a rostral, thalamic extension of the ...
The tract is situated in the central portion of the reticular formation. [1] Structure. The central tegmental tract contains descending and ascending fibers.
Hypothalamus: a center for the limbic system, connected with the frontal lobes, septal nuclei, and the brain stem reticular formation via the medial forebrain bundle, with the hippocampus via the fornix, and with the thalamus via the mammillothalamic fasciculus; regulates many autonomic processes
