The entorhinal cortex plays a crucial role in how we navigate through space and remember locations.
-
The blue-green trace shows neocortical slow oscillation, while the yellow trace shows the persistent activity of entorhinal cortical neurons, even when the inputs from the neocortex were silent.

Notably, Alzheimer's disease starts in the entorhinal cortex and patients have impaired sleep, so Mehta's findings may have implications in that arena.

Mehta's findings instead indicate that there is a third key actor in this complex dialogue, the entorhinal cortex, and that the neocortex is driving the entorhinal cortex, which in turn behaves as if it is remembering something.

Etymology
Entorhinal comes from Greek parts ento- 'within' and rhinal 'nose', like the 'rhino' in rhinoceros. So, the entorhinal cortex is a small brain area next to the smell region of the brain, which helps explain its role in memory and navigation.
