‭3‬‭regions‬‭of‬‭the‬‭brain-‬
‭1.‬‭Forebrain‬‭-‬‭LARGEST‬‭part‬‭of‬‭brain.‬‭Includes‬‭cortex‬‭(outer‬‭layer‬‭of‬‭brain‬‭&‬‭divided‬‭in‬‭4‬‭lobes‬‭where‬
‭your‬‭executive‬‭functions‬‭occur‬‭(planning,‬‭considering‬
‭consequences,‬‭etc.)‬
‭2.‬‭Midbrain‬‭-‬‭RELAY‬‭SYSTEM.‬‭In‬‭the‬‭uppermost‬
‭part‬‭of‬‭brain‬‭stem‬
‭3.‬‭Hindbrain‬‭-‬‭includes‬‭upper‬‭part‬‭of‬‭spinal‬‭cord,‬
‭brain‬‭stem,‬‭and‬‭cerebellum‬‭(largest‬‭part‬‭of‬‭hindbrain,‬‭looks‬
‭like‬‭wrinkled‬‭ball‬‭of‬‭tissue).‬‭governs‬‭the‬‭automated‬‭body‬
‭functions‬‭(heartbeat,‬‭breathing)‬

‭Brains‬‭4‬‭lobes-‬
‭1.‬ F‭ rontal‬‭-‬‭decision‬‭making,‬‭organizing‬‭behavior‬
‭not‬‭fully‬‭developed‬‭till‬‭25‬
‭2.‬ ‭Parietal‬‭-‬‭senses‬‭+‬‭movement‬
‭3.‬ ‭Occipital‬‭-‬‭vision‬
‭4.‬ ‭Temporal‬‭-‬‭hearing‬‭+‬‭emotions‬

‭Emotional‬‭brain‬‭→‬ ‭limbic‬‭system‬‭is‬‭the‬‭area‬‭where‬‭emotions‬‭such‬‭as‬‭pleasure,‬‭fear,‬‭reward,‬‭and‬
‭arousal‬‭originate‬
‭Self-regulation‬‭is‬‭part‬‭of‬‭executive‬‭function‬‭.‬‭uses‬‭the‬‭cortex‬‭.s‬‭kills‬‭to‬‭manage‬‭emotions,‬‭pay‬
‭attention,‬‭behavior,‬‭and‬‭body‬‭movement.‬‭teen‬‭brain‬‭needs‬‭self-regulation‬‭skills‬‭to‬‭filter‬‭distractions,‬
‭prioritize‬ ‭tasks,‬‭set/‬‭achieve‬‭goals,‬‭and‬‭control‬‭impulses‬‭.‬
