Overexpression of orexins leads to non-rapid eye movement (non-REM) sleep fragmentation with an occasional reduction in REM sleep [47]. WebOrexins (or hypocretins) are hypothalamic neuropeptides with a multitude of physiological functions. They occur in two known forms, namely, orexin A and orexin B with a common precursor, preproorexin. The orexin receptors (orexin 1R and orexin 2R) belong to the Family of G-protein coupled receptors. swadley\u0027s locations https://poolconsp.com
