Benjamin A. Eaton, Ph.D.



Dr. Benjamin Eaton's laboratory is interested in understanding how neurons maintain stable neurotransmission over extended periods. Importantly, age-dependent synaptic dysfunction is believed to be an important contributor the declines in cognition and motor function in the elderly. 

We predominantly use the Drosophila model system, which allows for a combination of powerful genetic techniques, animal behavior, in vivo imaging, and electrophysiology to asses synapse function from the cellular to the whole animal level. 

The lab is primarily focused on elucidating the molecular mechanisms underling the regulation of synaptic proteasomes, effects of diet and age on neuromuscular performance, and the role of the biosynthetic pathway for normal neurotransmission.
