Neurobiology, the study of the nervous system, is a field of science that investigates the biological mechanisms that underlie behavior as well as how brains process information. With advances in the field, we can now harness biometric data to map and measure whatâs happening in our bodies and brains when weâre experiencing both the ordinary and extraordinary. By deliberately shifting our neurophysiology - our breathing, posture, facial expressions, movements, or brainwaves - we can reverse-engineer a whole host of non-ordinary states.
