Discovery Matters69. Never underestimate a cellWe should not underestimate cells. Conor and Dodi talk with Dr Brett Kagan who conducted research to understand the brain and test ‘sentient’ brain cells, using the 1970s game, known as ‘Pong’. In another conversation, Professor Petra Levin and Kunaal Joshi explain how they have demonstrated that there is no mythical ‘average’ cell which mimics the stochastic behaviors of any individual cell. At the end of this episode, we hope to have proven that cells are not to be overlooked and still have so much to tell us about human health. Show notes In vitro neurons learn and exhibit sentience when embodie...
