The laterodorsal tegmental nucleus (LDT), also known as the laterodorsal tegmental area, is a pontine structure that provides cholinergic inputs to key forebrain structures involved in wakefulness, attention, and reward processing. The LDT is a critical component of the ascending arousal system and plays essential roles in regulating behavioral state, sleep-wake transitions, and cognitive function. This page explores the LDT's anatomy, neurochemistry, and relevance to neurodegenerative diseases including Parkinson's disease, Alzheimer's disease, dementia with Lewy bodies, and multiple system atrophy.

Anatomy and Location
The laterodorsal tegmental nucleus is located in the pontine tegmentum, ventral to the superior cerebellar peduncle and dorsal to the pontine reticular formation. It extends from the level of the trochlear nucleus to the mesopontine junction. [@kelley2019]
Subdivisions
Compact part: Densely packed cholinergic neurons
Diffuse part: Scattered neurons with mixed neurochemistry
Peri-LDT regions: Adjacent cholinergic cell groups
Cellular Composition
Cholinergic neurons: Primarily pontomesencephalic cholinergic cell group (Ch6)
GABAergic neurons: Local interneurons and projection neurons
