Conversation with Nic Rouleau, part 2: neuroscience, memory transfer, aging of cognition, and more

This is a ~55 minute discussion following up on Nic's talk and our brief conversation ( comprising part 2 of a conversation with a really interesting young neuroscientist, as well as friend, collaborator, and our Center member, Nicolas Rouleau ( We cover topics of consciousness, neural decoding, the meaning of neuroscience, memory transfer, cognitive plasticity and its relationship to rejuvenation therapies, intelligence throughout the universe, and the weirdest work Nic has done (he chose his work on memory in Playdoh).
