The laterodorsal tegmental nucleus (LDT), also known as the laterodorsal tegmental nucleus of Gudden, is a pontine tegmental nucleus located in the dorsal mesopontine tegmentum. This nuclei contains cholinergic neurons that project extensively to forebrain structures and play critical roles in arousal, reward processing, and cognitive function[@jones2005].

Overview
Mermaid diagram (expand to render)
The laterodorsal tegmental nucleus is one of two major cholinergic nuclei in the mesopontine tegmentum (the other being the pedunculopontine nucleus). LDT neurons are primarily cholinergic (producing acetylcholine) and send dense projections to the thalamus, basal forebrain, and other limbic structures, making them important modulators of cortical activation and limbic function["@steriade1990"].
