Here, we propose that entorhinal grid-like codes make an essential contribution to socio-spatial navigation. Sixty human participants underwent functional magnetic resonance imaging (fMRI) while observing and re-tracing different paths of a demonstrator that navigated a virtual reality environment. <span style=\"color: #ff0000;\"><strong>Results revealed that grid-like codes in the entorhinal cortex tracked the other individual navigating through space<\/strong><\/span>. Further,<strong><span style=\"color: #ff0000;\"> the activity of grid-like codes was time-locked to increases in co-activation and entorhinal-cortical connectivity that included the striatum, the hippocampus, parahippocampal and right posterior parietal cortices<\/span><\/strong>, altogether modulated by accuracy when subsequently re-tracing the paths. This suggests that network dynamics time-locked to entorhinal grid-cell-related activity might serve to distribute information about the <strong><span style=\"color: #ff0000;\">&#8220;socio-spatial map&#8221;<\/span> <\/strong>throughout the brain.&#8221;<\/p>\n<p style=\"text-align: justify;\">Isabella C Wagner, Luise Graichen, Boryana Todorova, Andre Luettig, David Omer, Matthias Stangl, Claus Lamm. <a href=\"https:\/\/www.biorxiv.org\/content\/10.1101\/2022.10.08.511403v1\"><strong>Entorhinal grid-like codes and time-locked network dynamics track others navigating through space<\/strong><\/a>. bioRxiv 2022.10.08.511403; doi: https:\/\/doi.org\/10.1101\/2022.10.08.511403<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Isabella C Wagner, Luise Graichen, Boryana Todorova, Andre Luettig, David Omer, Matthias Stangl, Claus Lamm.
