Study reveals a neural basis for how the brain enables odors to elicit memories
Odors evoke powerful memories, an experience enshrined in literature by Marcel Proust and his beloved madeleine.
A new Northwestern Medicine paper is the first to identify a neural basis for how the brain enables odors to so powerfully elicit those memories. The paper shows unique connectivity between the hippocampus the seat of memory in the brain and olfactory areas in humans.
This new research suggests a neurobiological basis for privileged access by olfaction to memory areas in the brain.

It s like a superhighway from smell to the hippocampus.
