Optogenetic Dissection of Brain Circuits Causing Levodopa-Induced Dyskinesia

Patients with Parkinson’s Disease eventually develop complications of the main medical therapy available, levodopa, or L-dopa. These complications include disabling involuntary movements triggered by levodopa. We do not know why these complications develop, nor do we have good medications to manage them. We propose to study Parkinsonian mice treated with levodopa (who develop involuntary movements similar to those of humans) to identify the parts of the brain which cause the problem. By using new optical techniques that allow us to turn on or off specific classes of nerve cells within the brain, including those which we believe cause involuntary movements, we can determine which classes are responsible. We hope this will help find new targets for drug treatments for this disabling complication of Parkinson’s Disease

Heterochromatin Mechanisms of Cortical Expansion
Neurodevelopmental disorders, such as autism and schizophrenia, are frequently associated with mutations in genes that encode chromatin-modifying enzymes. A subset of these mutations is thought to disrupt compacted chromatin (heterochromatin),…

Elucidate the Molecular and Cellular Targets of Caloric Restriction in Rejuvenating Aged Mammalian Brain
As we age, the brain’s ability to function declines, increasing the risk of cognitive impairments and neurological diseases like Alzheimer’s and Parkinson’s. Our research investigates how caloric restriction (CR), a…

Understanding the Mechanisms of Micturition in the Brain and Spinal Cord
This research aims to better understand how the brain and spinal cord work together to control urination, a process known as micturition. In healthy individuals, this process is carefully coordinated…
