Drosophila larvae exhibit rolling motor behavior as an escape response to avoid predators and painful stimuli. We introduce an accessible method for applying optogenetics to study the motor circuits driving rolling behavior. For this. we simultaneously implement the Gal4-UAS and LexA-Aop binary systems to express two distinct optogenetic channels. https://www.infonoticiasgandia.com/product-category/patio-heaters/
