Serotonergic cell groups refer to collections of neurons in the central nervous system that have been demonstrated by histochemical fluorescence to contain the neurotransmitter serotonin (5-hydroxytryptamine). [1] Since they are for the most part localized to classical brainstem nuclei, particularly the raphe nuclei, they are more often ...
Identifiers. Latin. nucleus reticularis ventralis. NeuroNames. 733. Anatomical terms of neuroanatomy. [ edit on Wikidata] The ventral reticular nucleus is a continuation of the parvocellular nucleus in the brainstem. The ventral reticular nucleus has been shown to receive afferent projections from the dentate gyrus in rabbits.
The rostral ventromedial medulla ( RVM ), or ventromedial nucleus of the spinal cord, [1] [2] is a group of neurons located close to the midline on the floor of the medulla oblongata (which develops from myelencephalon in embryonic development ). The rostral ventromedial medulla sends descending inhibitory and excitatory fibers to the dorsal ...

Jul 24, 2023 · The raphe nuclei are located midline throughout the brainstem within the pons, midbrain, and medulla. The majority of neurons located in the raphe nuclei are serotonergic. The more rostral raphe nuclei appear to be important in various bodily functions, including pain sensation and mood regulation.
The sleep neurons in the preoptic area receive inhibitory inputs from some of the same regions they inhibit, including the tubermammillary nucleus, raphe nuclei, and locus coeruleus. Thus, they are inhibited by histamine, serotonin, and norepinepherine. This mutual inhibition may provide the basis for establishing periods of sleep and waking.
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. These afferent connections have been proven to project not only ipsilaterally, but also to ...
