Optogenetics and Neural Behavior Concepts

Uma discusses optogenetics, a technique combining genetic engineering and light to control neurons. This method offers precise control over brain activity, unlike traditional electric stimulation. The talk highlights its application in OCD research, particularly targeting the VTA in mice, leading to insights into repetitive behaviors. The research involves detailed data analysis using tools like DeepLabCut and B-Side. Optogenetics holds promise for understanding and treating neuropsychiatric diseases, marking a significant advancement in neuroscience.
