Your gut may help your brain decide what to remember
✦AI Summary
New research suggests that the gut communicates with the brain via the vagus nerve to influence memory formation, particularly regarding food. Experiments with rats show that nutrient-rich food triggers acetylcholine release, which is essential for memory, while low-calorie alternatives do not.
The taste of a madeleine famously sent French writer Marcel Proust back into vivid memories of childhood. New research suggests that this kind of recollection may involve more than the brain alone. Signals from the digestive system may also help determine which food-related experiences become memories.
