The quartet theory of human emotions: An integrative and neurofunctional model
2015, Physics of Life ReviewsCitation Excerpt :Via the autonomic nerve fibres, the brainstem modulates activity of all extra-nervous organ systems, and thus modulates peripheral-physiological arousal. For example, the sympathetic sweat response can be elicited by electrical stimulation of different brainstem nuclei [19–21], and stimulation of neurons of the nucleus tractus solitarius (NTS, which has direct bidirectional connections with the RF) [22,23] decreases blood pressure and heart rate. Note that the NTS also projects to the hypophysotrophic zone of the paraventricular nucleus of the hypothalamus (PVN) [24], and that serotonergic neurons of the (median) raphe nuclei activate serotonin 2A receptors on PVN neurons [25].
Interoception and autonomic nervous system reflexes thermoregulation
2013, Handbook of Clinical NeurologyCitation Excerpt :Another transient receptor potential cation channel, subfamily V (TRPV), is expressed in the epidermis and TRPV4 is considered to be a sensor of extrinsic stimuli such as temperature and other physical or chemical factors (Denda et al., 2007; Akazawa et al., 2012; Almeida et al., 2012; Premkumar and Abooj, 2013). Recent work in humans using controlled skin temperature suits and functional MRI with a region of interest containing the ventral midline of the rostral medulla concluded that human rostral medullary raphe neurons are selectively activated in response to a thermoregulatory challenge and point to the location of thermoregulatory neurons homologous to those of the raphe pallidus nucleus (rRPa) in rodents and cats (Horiuchi et al., 2004; Asahina et al., 2007). Cortical elements involved in both autonomic and behavioral thermoregulation have been investigated recently.
Differences in skin sympathetic involvements between two chronic autonomic disorders: Multiple system atrophy and pure autonomic failure
2009, Parkinsonism and Related DisordersCitation Excerpt :In addition, SSwR is usually evoked with SkVR [1–3]. Although the central pathways of SSwR and SkVR remain unclear [2–4], the final afferent pathways are post-ganglionic sympathetic fibers. Therefore, SSwR and SkVR tests are useful for the assessment of cutaneous autonomic function in neurological disorders [1–3].
Measurements of sweat response and skin vasomotor reflex for assessment of autonomic dysfunction in patients with diabetes
2008, Journal of Diabetes and its ComplicationsCitation Excerpt :However, our diabetic patients presented no focal signs indicating central lesions. In addition, they showed abnormalities in both SSwR and SkVR responses, while disorders with central lesions often presented a discrepancy between involvement of SSwR and involvement of SkVR (Asahina, Kikkawa, et al., 2003; Kikkawa et al., 2003), the reflex centers of which are located at different sites (Asahina et al., in press). In conclusion, we consider SSwR and SkVR to be useful indexes for evaluating autonomic involvement in diabetic patients, doing as good a job as conventional cardiovascular autonomic function tests.
