Gut-Brain Highway: Vagus Nerve Links Diet to Memory Through Acetylcholine
TL;DR Summary
A rat study shows the vagus nerve senses gut state during eating and triggers acetylcholine release in the brain, supporting attention and memory; disrupting this pathway impairs cognitive signaling, and a Western-style high-fat/high-sugar diet may further weaken it, offering clues about diet-related cognitive decline and aging-related diseases like dementia.
