Medial Entorhinal Cortex

@@Home -> BiologicalLifeResearch -> BrainAreaFMM -> BrainRegionFMM_NC_PH_MEC

This page covers biological details of component Medial Entorhinal Cortex. Region is part of aHuman target integrated biological model.

• Top-down path to region: Cerebral Cortex -> Parahippocampal Lobe (NC.LOBE.PH) -> Anterior Parahippocampal Gyrus (FMM.NC.PHA) -> Rhinal Cortex (NC.PHA.RH) -> Entorhinal Cortex (FMM.NC.PH.ET) -> Medial Entorhinal Cortex (FMM.NC.PH.MEC) (see Mind Maps)
• Type: cortex
• Brain area: Forebrain - Memory Management Area
• Brodmann ID: 28
• Role: processor.memory.complex
• Function: Memory consolidation, basic, view independent position
• Notes to function: spatial input to HC; grid cells; path integration computations based on a global frame of reference, primarily using internally generated, self-motion cues and external input about environmental boundaries and scenes; provides hippocampus with coordinate system that underlies spatial context of experience
