This episode I explain the mechanisms by which different types of memories are established in our brain and how to leverage the amount and timing of key neurochemicals and hormones, such as adrenaline (aka epinephrine) and cortisol, to improve your learning and memory abilities. I describe multiple science-based protocols to do this, including repetition, caffeine, emotional states, deliberate cold exposure, sleep, meditation, and the role of vision, including taking “mental snapshots.” I also describe how exercise and an associated hormone, osteocalcin, can improve cognitive ability and memory formation. I also describe unique aspects and forms of memory such as photographic memory, extreme facial recognition (aka super recognition), and the phenomenon known as déjà vu.
