Dorsolateral Cornu Ammonis of Hippocampus

@@Home -> BiologicalLifeResearch -> BrainAreaFMM -> BrainRegionFMM_FT_HC_CA2

This page covers biological details of component Dorsolateral Cornu Ammonis of Hippocampus. Region is part of aHuman target integrated biological model.

Top-down path to region: Forebrain Telencephalon -> Hippocampal Formation (HBA.FT.HF) -> Hippocampus (HBA.FT.HC) -> Dorsolateral Cornu Ammonis of Hippocampus (FMM.FT.HC.CA2) (see Mind Maps)
Type: cortex
Brain area: Forebrain - Memory Management Area
Role: processor
Function: Gate controlled by the activity of the supramammillary nucleus to control signal propagation between HC lamines
Notes to function: Hippocampus. Receives theta rithm input from Septum Nucleus; the only SUM projection in rat, the only converge from ET L2 and L3; social memory
