Neuroscientist Moriel Zelikowsky studies the neural mechanisms underlying stress, fear, and social behavior. On this episode of Impact Theory with Tom Bilyeu, she discusses her own research into how extreme social isolation affects mice and humans. She talks about what drew her to the science of emotions, why fear is adaptive, and presents some surprising reasons to question the general advice that PTSD sufferers should join support groups.
