Lateral Geniculate Nucleus
@@Home -> BiologicalLifeResearch -> BrainAreaNSA -> BrainRegionNSA_FD_LGN
This page covers biological details of component Lateral Geniculate Nucleus. Region is part of aHuman target integrated biological model.
- Top-down path to region: Forebrain Diencephalon -> Thalamus (FD.TH) -> Sensory Thalamus (FD.TH.SR) -> Lateral Geniculate Nucleus (NSA.FD.LGN) (see Mind Maps)
- Type: nucleus
- Brain area: Neocortical Brain - Sensory Aggregation Area
- Role: thalamic.sensory.primary
- Function: Temporal decorrelation
- Notes to function:
- Only 10% of inputs to LGN come from the retina. 90% are modulatory inputs from cortex and the brainstem
