This is a reworked submission of a bid made by At-Bristol in July 2013. The Trust's committee recommended we resubmit, taking into account their feedback and advice. As suggested, we have consulted Professor Roger Kneebone and secured expert support on Bioethics. Working with the neuroscience centre at Frenchay Hospital, Bristol and the Centre for Ethics in Medicine, University of Bristol, At-Bristol will create an innovative and immersive workshop that engages At-Bristol visitors with neuros cience and neuroscience research. The workshop will model as closely as possible the work done to diagnose brain tumour tissue during brain surgery. By following the journey of a fictional patient we will create a compelling and memorable learning experience. The workshop will provide hands-on opportunities for At-Bristol visitors to investigate real human and animal brain tissue and will stimulate discussion about the social, ethical and legal issues around neuroscience and neuroscienc e research. Through formative testing with At-Bristol visitors and consultation with relevant patient groups we will work in collaboration with the Centre for Ethics in Medicine to develop dialogue resources that are embedded into the workshop. Workshops will take place in Live Lab, At-Bristol's open access lab space on the exhibition floor. The project will build on our experience developing a successful programme of dissections and biomedical investigations for Live Lab and our track re cord developing dialogue activities. The project aims to explore the impact of investigating human tissue on visitors' learning in informal learning experiences and share that learning across the science communication sector.
