Research in the Cheer Lab is aimed at elucidating fundamental neural mechanisms
underlying motivated behaviors, and how these are modulated by the recently
described endogenous cannabinoid system.
Our research seeks to extract neurobiological correlates of certain behaviors, within specifically defined anatomical frameworks to understand how key neural circuits in the brain function.
We use advanced state-of-the-art electrophysiological and neurochemical techniques to examine the activity patterns of individual neurons as well as neuronal populations and how these are regulated via neurotransmitters (dopamine in particular). We have recently implemented the use of a sensor that allows for the simultaneous measurement of neuronal firing and neurotransmitter release.
These techniques are particularly useful for elucidating specific temporal relationships between behavior and brain activity.
