WebEgocentric boundary vector sensitivity was primarily observed in dysgranular RSC, where 38.7% ( n = 89/230) of neurons recorded were classified as EBCs (fig. S1C). In contrast, EBCs were observed in 9.9% ( n = 24/241) of granular RSC and 25.0% ( n = 21/84) of intermediary area cells between the two subregions. WebThus, boundary vector cell firing is consistent across different environments, conforms to the predictions of the model, and differs from place cells recorded in the same situation.
