Use of a running wheel for 6 weeks increased the expression of the mRNA for 5-HT1A, an autoreceptor that inhibits the synthesis and release of 5-HT, in the raphe (90); six weeks of wheel running also increased the mRNA for tyrosine hydroxylase in the SNpc and for D2 receptors in the caudate-putamen (66).
Moreover, EA stimulation of acupoint Zusanli inhibited visceral pain; fos expression in the brainstem nucleus raphes dorsalis, shallow SDH, and colonic epithelium; and 5-HT expression in the nucleus raphes dorsalis and the SDH in a rat model of visceral pain caused by neonate-mother separation [63].

In addition, a study demonstrated reduced expression of tryptophan hydroxylase (TPH) and 5-HT1A receptors in the dorsal raphe after rotenone injection, leading to a depressive-like behavior; this effect was improved with treadmill exercise [78].

The neuronal somas that release this substance are also found in the locus coeruleus, tegmental ventral area, and dorsal raphe; which modulate the monoaminergic neurotransmitter systems (Coplan et al., 1996).
Furthermore, ziram appeared selectively toxic to DA neurons because serotonergic neurons in the raphe nuclei of the VMAT2 transgenic line were unaffected by ziram exposure (Figure 1h-j).
There was no evidence of suprasternal clefting and supra umbilical raphe while the rest of general physical and systemic examinations were un-remarkable.
TRP channels allow cations such as sodium, calcium, and magnesium to pass across membranes and are abundantly expressed in sensory nerves in the oropharyngeal space (see Figure 1), including the trigeminal (V), glossopharyngeal (IX), and vagus (X) nerves that project directly and indirectly to the solitary tract nucleus in the lower brainstem, which in turn has connections to various targets in the brain and brainstem, including the locus coeruleus and the dorsal raphe nucleus.
The stress-bearing areas in the maxillary arch are the horizontal plates of the palatine bone, and the relieving areas are midpalatine raphe and the incisive papilla.
