Nucleus Of The Lateral Olfactory Tract (Nlot) Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The Nucleus of the Lateral Olfactory Tract (NLOT) is a ventral pallidal structure that serves as a critical relay in the olfactory limbic pathway, connecting the olfactory bulb to the amygdala and other limbic structures involved in emotion and memory. [1]
