The raphe nuclei are traditionally considered to be the medial portion of the reticular formation, and appear as a ridge of cells in the center and most medial portion of the brain stem . In order from caudal to rostral, the raphe nuclei are known as the nucleus raphe obscurus, the nucleus raphe pallidus, the nucleus raphe magnus, the nucleus ...

May 1, 2023 · The raphe nuclei are positioned midline in the brainstem throughout the midbrain, pons, and medulla. These nuclei contain primarily serotonergic neurons, which release serotonin (5-hydroxytryptamine) with autocrine and paracrine effects, as well as synaptic connections.

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.

Aug 16, 2023 · There is a lateral, a medial and a median (raphe) group of nuclei. Recall that the brainstem is symmetrically divided by the dorsal median sulcus (continuing from the dorsal surface of the spinal cord). Therefore, the three groups of nuclei described previously are mirrored in each half of the brainstem.
Jul 24, 2023 · These three columns from medial to lateral are the raphe nuclei, located in the midline of the reticular formation core, the gigantocellular reticular nuclei more laterally, and the parvocellular reticular nuclei, which comprises the most lateral aspect of the column system.
Where are the raphe nuclei located? The term “raphe”, in regard to anatomical location, refers to a line or indentation separating two symmetrical parts of the body. Researchers chose it to designate these nuclei. This is because of their arrangement around the midline of the brainstem, located between the brain and the spinal cord.
