In April 2021, in partnership with the UK Dementia Research Institute, the British Neuroscience Association will host its fifth Festival of Neuroscience. Due to the ongoing uncertainty around COVID19, our 2021 event will be the first ever online Festival of Neuroscience. Although we are sorry to miss meeting in person, we're excited to create a whole new Festival experience! The ambition and scope of the BNA Festivals make them unparalleled across neuroscience. Being online will not change how the BNA2021 event will: - bring together multiple organisations with an interest in brain research at a single, shared event, creating a novel, multi-organisation forum featuring all areas of fundamental research in neuroscience and psychology, from both academia and the commercial sector, plus clinical expertise in neurology and psychiatry. - include a programme of public events as well. Past Festivals have seen a rap performance about consciousness, lunchtime talks, sessions in schools, and much more.
