Objective: Most of the bodily functions are regulated by multiple interactions between the parasympathetic (PNS) and sympathetic (SNS) nervous system. In this study, we propose a novel framework to quantify the causal flow of information between PNS and SNS through the analysis of heart rate varia...
In contrast, islet parasympathetic innervation, inferred from pancreatic polypeptide secretion in response to insulin-induced hypoglycemia, appears intact in patients with T1D during the early stages of the disease and correlates with systemic epinephrine levels15,16. Direct innervation of α-cells in ...
In this regard, it is important to note that the effect of sympathetic regulation of CNS vascular tone may not be uniform across brain regions10,11, and that parasympathetic mechanisms may contribute as well43. Furthermore, sympathetic vascular tone is likely to have a co-modulating neuronal ...

Autonomic neurons that have their cell bodies in the brainstem or spinal cord and synapse onto visceral motor neurons (sympathetic or parasympathetic) in peripheral ganglia. Baroreflex Reflex decrease in sympathetic nerve activity that is initiated by the activation of stretch-sensitive afferents located ...

Nonetheless, the similarities between Tantric understandings of subtle physiology and contemporary neuroscientific mappings of autonomic nervous system are intriguing. Just as contemporary neuroscientists identify an autonomic nervous system with two distinct networks—the sympathetic and parasympathetic—responsible...
Figure 5. The Cholinergic Anti-inflammatory Pathway and Anti-inflammatory Response and HIV-1. The cholinergic anti-inflammatory pathway is an efferent two-neuron circuit, whereby the parasympathetic neurons in the dorsal motor nucleus (DMN) of the vagus nerve (gold neuron) inhibits proinflammatory cyt...
In the human, autonomic nerve fibers derive from two sources: sympathetic and, rarely, parasympathetic neurons [1]. The sympathetic innervations of the skin was characterized in humans [2–4] and other mammals, such as the rat [5], guinea pig [6], cat [7], rabbit [8], dog [9] ...
