From: Retrosplenial cortex in spatial memory: focus on immediate early genes mapping
Putative models of “hippocampal” and “retrosplenial” processing of spatial information. A Sensory input into superficial layers of MEC is forwarded to the hippocampus (LII MEC to DG and CA3, LIII MEC to CA1). The output of hippocampal processing is fed back to LV MEC and towards cortical areas. RSC is suppressed by inhibitory projections from CA1 and/or subiculum. B Sensory input to RSA and RSG is forwarded directly to the output neurons of LV MEC
