| Nucleus paramedianus dorsalis | Small nucleus in the brainstem of human, located adjacent and medial to the nucleus prepositus in the dorsal medulla, described in several atlases of human brain stem. In transverse sections, it is oval with its long axis aligned with the dorsal border of the brainstem. It begins at about the same A-P level as the nucleus prepositus, just rostral to the hypoglossal nucleus. It includes calretinin immunoreactive large cells with oval or polygonal cell bodies. Cells are not immunoreactive for either calbindin or parvalbumin, but a few fibers immunoreactive to each protein are found within its central region. Cells in PMD are also immunoreactive to nNOS, and immunoreactivity to a neurofilament protein shows many labeled cells and fibers. According to Baizer et al., no equivalent structure was observed in the cat, rat, mouse or monkey atlas although they did not look at the brains of the great apes. | ILX:0107786 | 11 | FDI Lab - SciCrunch.org | 01/17/2023 | FDI Lab - SciCrunch.org | term | 12/09/2016 | 0 | NeuroLex | NeuroLex |

| Nucleus raphe magnus | The nucleus raphe magnus, located directly rostral to the raphe obscurus, is afferently stimulated from axons in the spinal cord and cerebellum. This makes the magnus a likely candidate for part of the motor system; however, it seems to participate in the endogenous analgesia system. The magnus receives descending afferents from the periaqueductal gray, the paraventricular hypothalamic nucleus, central nucleus of the amygdala, lateral hypothalamic area, parvocellular reticular nucleus and the prelimbic, infralimbic, medial and lateral precentral cortices . All of these brain areas influence the main function of the raphe magnus. The main function of the magnus is mostly pain mediation; in fact it sends projections to the dorsal horn of the spinal cord to directly inhibit pain. The periaquiductal gray, the epicenter of analgesia, sends efferent connections to the nucleus raphe magnus in when it is stimulated by opiates (endogenous or otherwise). Electrical stimulation of the PAG produces analgesia, as well as administration of morphine to the PAG or n.r. magnus. The antinociceptic effects of electrical stimulation of the PAG can be blocked by administering naloxone, an opiate antagonist, to the n.r. magnus. All of this seems to indicate that the magnus is part of the endogenous opiate system, and acts to inhibit pain in the spinal cord.

| Nucleus raphe obscurus | The raphe obscurus projects to the cerebellar lobes VI and VII and to crus II along with the nucleus raphe pontis . This so called obscure nucleus has also been implicated in the modulation of the hypoglossal nerve. It has been observed that the ablation of this nucleus causes a change in the firing pattern in the XII nerve . In addition, the raphe obscurus mediates expiration via the inhibitory effect of serotonin and depresses periodic synaptic potentials . It has also been shown that this nucleus stimulates gastrointestinal motor function; microinjections of 5-HT into the n.r. obscurus increase gastric movement .

| Nucleus raphe pallidus | The nucleus raphe pallidus receives afferent connections from the periaqueductal gray, the paraventricular hypothalamic nucleus, central nucleus of the amygdala, lateral hypothalamic area, and parvocellular reticular nucleus. Also, the pallidus receives afferents from the medial preoptic area, median preoptic nucleus and lateral paragigantocellular reticular nuclei . The pallidus has recently been shown to be involved in the activation of a fever as an immunoreaction. It has been implied that the preoptic area is constantly inhibiting the raphe pallidus, especially the rostral portion, with GABA. When the preoptic area receives immune signals from the body, the inhibition stops and the rostral portion of the raphe pallidus excites the intermediolateral cell column, which induces a fever . The raphe pallidus has also been known to mediate the tachycardia response, an extremely high heart rate known to be incited by emotional or psychological stress. Microinjections of a GABA-a antagonist into the raphe pallidus, induces an increased heart rate. Conversely, microinjections of muscimol, a GABA-a agonist, inhibit tachycardia in rats under air-stress stimuli. In both of these cases, GABA is mediating two different sympathetic responses, so clearly the nucleus raphe pallidus is a far more a complex nucleus than previously thought.
