According to these authors, glucose would predominantly inhibit preganglionic excitatory neurons that make synapses with myenteric cholinergic neurons (37), slowing GE.

Scopolamine butylbromide is a synthetic, peripheral cholinergic receptor blocker that ameliorates the hyperreactivity of cholinergic receptors in the preganglionic sympathetic neurons and reduces the overcontraction of visceral smooth muscles.
In a stressful situation, a brain region called the amygdala sends out a stress signal to the hypothalamus, which induces the activation of the sympathetic nervous system and the release of the neurotransmitter acetylcholine from preganglionic sympathetic nerves.
In addition, it is also known to promote the synthesis of endogenous motilin, and subsequently stimulate cholinergic nerves of the gut at both preganglionic and postganglionic levels, which leads to the release of calcium and contraction of smooth muscle cells (2).
Thus, low frequency stimulation applied in preganglionic neurons is likely to have the same effects as the high frequency applied to the postganglionic neurons.
The bladder's detrusor muscle is controlled by sacral parasympathetic preganglionic neurons and lumbar sympathetic preganglionic neurons (18).
The goal of imaging the BP is to visualize the entire course of the neural network from its preganglionic segments (eg, nerve rootlets and intraforaminal nerve segments) and the postganglionic segments from the dorsal root ganglion (DRG) to the terminal branches.

Conversely, parasympathetics take their roots from the sacral afferent parasympathetic system S2-4 and reach the organs via preganglionic pelvic splanchnic nerves.
