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. <strong><span style=\"color: #ff0000;\">Results revealed that grid-like codes in the entorhinal cortex tracked the other individual navigating through space<\/span><\/strong>. 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. Surprisingly, the grid-related effects during observation were stronger the worse participants performed when subsequently re-tracing the demonstrator\u2019s paths. <strong><span style=\"color: #ff0000;\">Our findings suggests that network dynamics time-locked to entorhinal grid-cell-related activity might serve to distribute information about the location of others throughout the brain<\/span><\/strong>.&#8221;<\/p>\n<p style=\"text-align: justify;\">Isabella C.
