@@Home -> BiologicalLifeResearch -> BrainCenterFMM_FT_HF
This page covers biological details of component group Hippocampal Formation.
Component group is part of aHuman target integrated biological model.
- Top-down path to center: Forebrain Telencephalon -> Hippocampal Formation (FMM.FT.HF) (see Mind Maps)
- Function: Attention and short-term to long-term memory conversion
- Notes to function: allocortex

Components
(generated)
Component items:
- Hippocampus (FMM.FT.HC)
- Dentate Gyrus (FMM.FT.HC.DG): Distinguishing multiple instances of similar events
- Ventrolateral Cornu Ammonis of Hippocampus (FMM.FT.HC.CA1): Representing sequences of episodic memory - long-term
- Dorsolateral Cornu Ammonis of Hippocampus (FMM.FT.HC.CA2): Gate controlled by the activity of the supramammillary nucleus to control signal propagation between HC lamines
- Dorsomedial Cornu Ammonis of Hippocampus (FMM.FT.HC.CA3): Representing sequences of episodic memory - short-term
- Subiculum (FMM.FT.HF.SUB): Spatial navigation and mnemonic processing
