Whether speed and head direction signals provide invariant self-motion signals across environments or change their coding in response to metric changes to the environment

Munn, Robert GK, Caitlin S. Mallory, Kiah Hardcastle, Dane M. Chetkovich, and Lisa M. Giocomo. Entorhinal velocity signals reflect environmental geometry. Nat Neurosci (2020) doi:10.1038/s41593-019-0562-5

Abstract
“The entorhinal cortex contains neurons that represent self-location, including grid cells that fire …

How does the brain’s spatial map change when we change the shape of the room?

A latest report about grid cells from Sainsbury Wellcome Centre at UCL. The following is excerpted from the report. 

Our ability to navigate the world, and form episodic memories, relies on an accurate representation of the environment around us. …
