Dynamic changes in orbitofrontal-hippocampal connectivity linked to cognitive map formation in humans

Yidan Qiu, Huakang Li, S. T. Lin, Xiaoyu Zheng et autres

How the brain coordinates to represent cognitive maps? Although extensive evidence shows the roles of the hippocampus (HIP), parahippocampal cortex (PHC), orbitofrontal cortex (OFC), and retrosplenial cortex (RSC) in spatial navigation, the specific mechanisms by which these brain regions interact to form …
