Abstract

Grid cells in entorhinal cortex underlie spatial orientation and path finding. Bao et al. show that entorhinal grid-like codes with behavioral relevance emerge when humans mentally navigate an olfactory landscape, highlighting potential neural mechanisms for locating odor sources in odiferous environments.
