Tag olfactory bulb

Smells trigger memories because the sense of smell has a direct pathway to the brain's emotional and memory centers. Unlike sight or hearing, odor signals travel from the nose to the olfactory bulb, which communicates directly with the amygdala and hippocampus—the regions responsible for emotion and long-term memory. This unique neurological connection explains why the scent of fresh cookies, campfire smoke, or even a damp basement can instantly transport you back to a specific place, person, or moment in time.
