Overview. The visceral (or autonomic) motor system controls involuntary functions mediated by the activity of smooth muscle fibers, cardiac muscle fibers, and glands.
The visceral motor system is regulated in part by circuitry in the cerebral cortex: Involuntary visceral reactions such as blushing in response to consciously embarrassing stimuli, vasoconstriction and pallor in response to fear, and autonomic responses to sexual situations make this plain.
31 sie 2022 · Focusing on gut and upper airway stimuli, we observed that individual NTS neurons are tuned to detect signals from particular organs and are topographically organized on the basis of body...
24 lip 2023 · By targeting these three pathways, the visceral motor neurons in the sympathetic division contribute to the “fight-or-flight” response. On the other hand, in the parasympathetic system, the visceral motor neurons help give rise to cranial nerves III, VII, IX, and X.
20 lut 2013 · The close coupling of ventilation to other interoceptive processes (pH balance, cardiovascular function, inflammatory states) and motoric and affective behavior, suggests that respiration via CO 2 is a major bodily influence on brain processes.
29 kwi 2019 · Visceral signals automatically contribute to shaping spontaneous large-scale brain dynamics, even when not consciously experienced. To what extent ascending visceral signals can be consciously perceived remains a matter of debate.
