Navigating for reward

M Sosa, LM Giocomo - Nature Reviews Neuroscience, 2021 - nature.com
An organism's survival can depend on its ability to recall and navigate to spatial locations
associated with rewards, such as food or a home. Accumulating research has revealed that …

Speed cells in the medial entorhinal cortex

E Kropff, JE Carmichael, MB Moser, EI Moser - Nature, 2015 - nature.com
