This page covers biological details of component Laterodorsal Tegmental Nucleus. Region is part of aHuman target integrated biological model.

• Top-down path to region: Hindbrain Metencephalon -> Pontine Tegmental Nuclei (HT.TG) -> Laterodorsal Tegmental Nucleus (LMC.HT.TG.LDT) (see Mind Maps)
• Type: nucleus
• Brain area: Lower Brain - Modulatory Contol Area
• Role: relay
• Function: Modulating sustained attention or in mediating alerting responses
• Notes to function: sleep, waking, motor function, learning and reward
