“Goosebumps, tears, vagal tone, default mode network deactivation, vocalizations, body postures. I mean, man, we can measure it, and that in its own right some people would not have predicted.”

The researchers noticed that a particular subgroup of vagal sensory neurons was more active during this gasping behavior.

Recent literature suggests that that this communication occurred through physical connections known as synapses, and that EEC cells form very close junctions with vagal sensory endings.

To determine how fats and sugars affect the brain, the team stimulated gut vagal nerves with light.
