Hippocampal Formation
@@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
- Proximal CA1 of Hippocampus (FMM.FT.HC.CA1P): Long-term memory, spatial
- Middle CA1 of Hippocampus (FMM.FT.HC.CA1M): Long-term memory, synchronize
- Distal CA1 of Hippocampus (FMM.FT.HC.CA1D): Long-term memory, motivational
- 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
- Proximal CA3 of Hippocampus (FMM.FT.HC.CA3P): Representing sequences of episodic memory, spatial
- Middle CA3 of Hippocampus (FMM.FT.HC.CA3M): Representing sequences of episodic memory, synchronize
- Distal CA3 of Hippocampus (FMM.FT.HC.CA3D): Representing sequences of episodic memory, motivational
- Subiculum (FMM.FT.HF.SUB): Spatial navigation and mnemonic processing
- Proximal Subiculum (FMM.FT.HF.SUBP): Controlling hypothalamic-pituitary-adrenal (HPA) axis
- Middle Subiculum (FMM.FT.HF.SUBM): Dynamic bridging of temporal intervals
- Distal Subiculum (FMM.FT.HF.SUBD): Providing coarse representation of space
