Stuart Trenholm, PhD
Assistant Professor
Stuart Trenholm's lab studies how neural connectivity enables us to see objects around us. His work could discover new ways to improve the vision of people who have lost their sight聽by understanding how the specific wiring of neuronal circuits in the visual system leads to complex visually responsive neurons and ultimately leads to perception. The lab studies visual circuits in healthy, vision-impaired and vision-rehabilitated animals. The lab merges multiple disciplines, including physiology, animal behaviour, virology, genetics, disease models and optogenetics. Techniques in the lab include monitoring brain activity at cellular resolution using in vivo 2-photon calcium imaging, utilizing virus-mediated neuronal circuit tracing strategies, and implementing optogenetic vision restoration strategies.
