#27 The mind-blowing science to bring you back from death - neuroscientist Ariel Zeleznikow‑Johnston

When is someone really dead? What does it mean to survive? Is mind-uploading really a possible future way of surviving? These are some of the questions we are discussing with Dr Ariel Zeleznikow-Johnston.


Dr Ariel Zeleznikow‑Johnston is a neuroscientist and Research Fellow at Monash University in Melbourne, Australia, whose work delves into the neural basis of consciousness - from understanding how genetics and environment shape cognition to exploring the subtle qualities of perceptual experience such as color qualia. A 2019 PhD graduate from The University of Melbourne, he has published extensively on how cognitive function changes across the lifespan.

He is the author of The Future Loves You: How and Why We Should Abolish Death, which advocates for brain preservation technology as a means to suspend death and revive individuals in the future.

Check out Peter's review of the book here: https://reachlevity.com/p/a-clear-case-for-cryonics-a-review-of-the-future-loves-you


His multidisciplinary approach combines rigorous neuroscience with philosophy and ethics, positioning him at the forefront of contemporary debates about identity, mortality, and the future of human life.
