The dorsal raphe nucleus is one of the raphe nuclei. It is situated in the brainstem at the midline. It has rostral and caudal subdivisions: The rostral aspect of the dorsal raphe is further divided into interfascicular, ventral, ventrolateral and dorsal subnuclei.

2023年5月1日 · The dorsal raphe nucleus is situated between the oculomotor nucleus and mid-pons, extending from midline to the periaqueductal gray. The median raphe extends from the caudal edge of the superior cerebellar peduncles to the motor nucleus of V. Afferents for the dorsal raphe and median raphe come from the limbic system.

The Dorsal Raphe Nucleus (DR) is a region located in the ventral part of the central gray matter of the mesencephalon and rostral pons. It is characterized by its accumulation of large, darkly stained neurons and is subdivided into different parts.

The dorsal raphe nucleus is one of the seven bilateral brainstem nuclei located in the ventral periaqueductal grey matter of the mesencephalon, with a caudal tip projecting into the pons.

Serotonergic (5-HT) cells in the rat dorsal raphe nucleus (DRN) appear in topographically organized groups. Based on cellular morphology, expression of other neurotransmitters, afferent and efferent connections and functional properties, 5-HT neurons of the DRN have been grouped into six cell cluste …

The raphe nuclei (specifically the raphe magnus and dorsal raphe) are also involved in the natural inhibition of pain. Neurons from the raphe nuclei extend down to the spinal cord, where they inhibit neurons in the dorsal horn of the spinal cord that are responsible for transmitting pain signals.

The dorsal raphe nucleus (DRN) is a heterogeneous brainstem nucleus, located in mammals in the lateral and ventral (including midline) parts of the periaqueductal gray matter (PAG) of the midbrain.

The dorsal raphe nucleus (DRN) is a major source of neuromodulators in the central nervous system, and is the largest of the serotonergic nuclei, containing approximately a third of all serotonergic neurons (5-HT neurons) in the brain (Hornung, 2010).

The dorsal raphe nucleus (DRN) contains topographically organized subpopulations of serotonin (5-HT) neurons that provide the majority of serotonergic input to limbic forebrain structures involved in regulating complex emotional responses to stress.

2019年8月14日 · The dorsal raphe nucleus (DRN) is an important source of neuromodulators and has been implicated in a wide variety of behavioral and neurological disorders. The DRN is subdivided into distinct anatomical subregions comprised of multiple cell types, and its complex cellular organization has impeded e …
