As we move through the world, what we see is seamlessly integrated with our memory of the broader spatial environment. How does the brain accomplish this feat? A new study from Dartmouth College reveals that three regions of the brain in the posterior cerebral cortex, which the researchers call “place-memory areas,” form a link between the brain’s perceptual and memory systems. The findings are published in Nature Communications.
“As we navigate our surroundings, information enters the visual cortex and somehow ends up as knowledge of where we are — the question is where this transformation into spatial knowledge occurs. We think that the place-memory areas might be where this happens,” explains lead author Adam Steel, a Neukom Fellow with the department of psychology and brain sciences in the Robertson Lab at Dartmouth. “When you look at the location of the brain areas that process…
