I was chatting to a therapist friend the other day about EMDR [0] therapy. In short it’s often used in treating PTSD through alternating eye movement, but also alternating sound in headphones or tapping the body on alternating sides.

The theory is that it helps connect the left and right halves of the brain to allow trauma to be processed emotionally.

I’ve been wondering since if that’s why walking / running helps with creative processing?
