The annual Synapse virtual symposium series initiated by IISER Tirupati in 2020. This year, Synapse is jointly organized by IISER Tirupati and IISER Thiruvananthapuram and brings together a diverse assortment of neuroscientists from India and across the world. Neuroscience, despite being a young field, is one of the fastest-emerging interdisciplinary areas of science which allows scientists across different fields to work together. Symposia and conferences in this field are especially important in the Indian sub-continent, where established neuroscience researchers are very few in number, and conferences in specialized areas of neuroscience research are not frequently organized. This virtual symposium therefore aims to bring people together on one platform, and increase scope for networking and visibility of neuroscience/neurobiology researchers.
