RECENT SUCCESS CASE

Head-fixed subcortical single-cell calcium imaging with Mightex OASIS Fiberscope

The Kravitz Lab investigates the circuits underlying hedonic feeding using cellular-resolution Ca2+ imaging and optogenetics during consumption of obesogenic foods. We used the Mightex OASIS Fiberscope to record Ca2+ dynamics from genetically identified ventral pallidum neurons (VPGABA and VPGlu) in awake, head-fixed mice. We observed proportionally similar levels of activation and inhibition during licking behaviour (high calorie Ensure reward) in VPGABA and VPGlu neurons. However, active VPGABA neurons had Ca2+ dynamics that scaled with consumption duration. This suggests that a subpopulation of VPGABA neurons is highly responsive to palatable reward consumption and might be a mechanistic target for suppressing hedonic feeding that underlies diet-induced obesity.

Head-fixed subcortical single-cell calcium imaging with Mightex’s OASIS Fiberscope

The OASIS Fiberscope’s integration with a scientific-grade camera (pco.panda sCMOS) enabled these cellular-resolution recordings through superior spatial resolution, sampling rates, and illumination control. The Mightex PolyScan4 acquisition software facilitated reliable synchronization of Ca2+ imaging with behavioural timestamps, allowing precise alignment of neural activity with licking microstructure and consumption duration.

About the Scientists
Justin Wang

Justin G. Wang is a doctoral trainee in the Neurosciences program at Washington University in St. Louis., enrolled since 2020, under the supervision of Alexxai V. Kravitz, PhD. He earned his undergraduate degree from New York University in 2018. His research focuses on dissecting striatopallidal circuits that modulate feeding behaviour, with the goal of advancing our understanding of neural mechanisms underlying motivation and appetite.

Dr. Alexxai V. Kravitz

Dr. Alexxai V. Kravitz is an Associate Professor of Neuroscience and Anesthesiology and serves as Interim Division Director for Basic Neuroscience at Washington University in St. Louis. His research focuses on basal ganglia circuitry and how its function is altered in disease states such as obesity, addiction, and anxiety disorders. Under normal conditions, his work examines how basal ganglia networks drive the selection of adaptive behavioural outcomes, providing insight into both healthy and pathological brain function.
