---

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: relay
• 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
