WebbMost neural pathways from MnPO to RMM-raphé are not direct and involve disinhibition of an indirect inhibitory pathway to glutamatergic neurons in either the RMM-raphé in the case of skin vasoconstriction (Tanaka et al., 2011) or dorsomedial hypothalamic nucleus in the case of shivering or brown adipose tissue thermogenesis (Morrison, 2016). A thermoreceptor is a non-specialised sense receptor, or more accurately the receptive portion of a sensory neuron, that codes absolute and relative changes in temperature, primarily within the innocuous range. In the mammalian peripheral nervous system, warmth receptors are thought to be unmyelinated C-fibres (low conduction velocity), while those responding to cold have both C-fibers and thinly myelinated A delta fibers (faster conduction velocity). The adequate stimulus for …
