Vagus Nerve
The tenth cranial nerve, connecting the brainstem to the internal organs. Approximately 80% of its fibers are afferent, carrying signals from the gut to the brain.
Timeline (last 90 days)
Kanoski's research revealed a three-stage pathway from the gut to the hippocampus: gut signals travel via the vagus nerve to the nucleus of the solitary tract in the brainstem, then project to the medial septum, and finally reach the hippocampus via cholinergic neurons.
About 80% of the fibers in the vagus nerve are afferent fibers, transmitting gut sensory information one-way to the brain.
