Nucleus of the solitary tract

Figure 7.4 Summary of some of the wide array of afferent and efferent connections of midbrain dopaminergic neurons (SN/A9, RRF/A8, and VTA/A10 in center of figure). This emphasizes their potential involvement in coordination of seemingly disparate behaviors inclusive of the sleep-wake state of the organism. Abbreviations BP, blood pressure BST, bed nucleus of the stria terminalis CEA, central nucleus of the amygdala MEA, midbrain extrapyramidal area NTS, nucleus of the solitary tract O2, oxygen tension PPN, pedunculopontine tegmental nucleus RRF, retrorubral field SN, substantia nigra VTA, ventral tegmental area.

A major side-effect of morphine is respiratory depression. Opiates are believed to cause this effect via actions in brainstem nuclei, fi receptor immunoreactivity and mRNA were detected in neurons of the nucleus of the solitary tract, nucleus ambiguous, and parabrachial nucleus. mRNA was detected in the bed nucleus of the stria terminalis which projects to the nucleus of the solitary tract, fi receptor immunoreactivity is found in the nucleus of the solitary tract and dorsal rhizotomy reduced receptor immunoreactivity in the nucleus suggesting a presynaptic localization of the receptor. [Pg.465]

The vagus nerve terminates in the nucleus of the solitary tract with widespread projections, including the locus ceruleus. There are several lines of evidence that support the potential efficacy of vagus nerve stimulation (VNS) for depression, including the following ... [Pg.179]

Structures implicated in the production or maintenance of sleep include the nucleus of the solitary tract, dorsal medullary reticular formation, raphe nuclei, thalamus, anterior hypothalamus, preoptic area, basal forebrain, orbitofrontal cortex, caudate nucleus, basal ganglia, and cerebral cortex. None of these structures are individually necessary for sleep. No lesion has produced a long lasting total insomnia. After some sleep-reducing lesions, sleep returns toward normal if sufficient time is allowed for recovery. [Pg.567]

The NAc receives brainstem information related to taste and visceral functions through direct input from the nucleus of the solitary tract to the medial shell as well as indirect input from the gustatory cortex to the lateral shell and core via parabrachial projections to the gustatory thalamus (Ricardo and Koh, 1978 Saper, 1982). Additonal taste information is relayed to the NAc from the basolateral amygdala, that integrates taste... [Pg.305]

Efferent projections from the NAc core and shell topographically terminate in the lateral and medial ventral pallidus respectively, but in addition the NAc shell targets the lateral hypothalamus, central grey and nucleus of the solitary tract (Heimer et al., 1991). [Pg.306]

NPY, a 36-residue, highly conserved peptide that is widely distributed throughout the vertebrate nervous system. NPY delivers a powerful orexigenic (appetite-promoting) signal within the hypothalamus, which activates a neural pathway leading to the nucleus of the solitary tract. NPY is over-produced in leptin-deficient mice and may mediate the overfeeding observed in leptin-deflcient animals. [Pg.59]

Lipid signals therefore appear to be transmitted by a peripheral nerve route known to be involved in the transfer of gustatory information to the brain. The nucleus of the solitary tract (NST) in the brainstem is the first synaptic relay in the nervous gustatory cascade. Immunohistochemical detection of Fos, the protein encoded by the immediate early gene c-fos, has been successfully used to identify populations of neurons activated by LCFA in the NST (Gaillard et al. 2008). In mice, oral linoleic acid deposition triggers the activation of NST areas known to receive CT and... [Pg.240]
