π§ The teenage brain undergoes two monumental changes: synaptic pruning and myelination.
π± Synaptic pruning is the process of cutting away unused synaptic connections in the brain, leading to more specialized knowledge.
π‘ As teenagers grow older, their brains become more focused and narrow in their areas of expertise.
π§ Synaptic pruning increases efficiency in the teenage brain.
β‘οΈ Myelination speeds up the signal transmission in the adolescent brain.
π§ Myelination increases the speed of signals in the brain by a hundred times.
π₯ The brain consists of gray matter (cortex) and white matter (myelinated axons).
π± During teenage life, the brain undergoes synaptic pruning and myelination.
π© As the brain develops from back to front, the prefrontal cortex, responsible for executive functioning, is the last part to mature.
π§ The limbic system, responsible for emotions, develops before the rational part of the brain.
π The amygdala, located in the limbic system, is the center of emotion and alerts us to danger.
π€ The prefrontal cortex is the rational part of the brain and is involved in thoughtful decision-making.
π§ The teenage brain undergoes synaptic pruning and myelination, leading to changes in impulse control and emotional regulation.
π² Teenagers are more prone to risk-taking behavior due to the high levels of dopamine in their brain, which influences decision-making.
π± The release of dopamine is more intense in adolescents when engaging with social media, influencing their behavior and motivation to repeat certain actions.
π§ͺ Dopamine surge in the teenage brain drives risk-taking behaviors.
π Teenagers are at the highest risk of car crashes due to the rewarding nature of risky activities.
π₯ Peers have a significant influence on teenagers' risk-taking behavior.
β° The circadian rhythm is the internal biological clock that controls our sleep-wake cycles.
π Melatonin, released by the pineal gland, regulates sleep and is released at different times in children and teenagers.
π΄ Teenagers experience a shift in their circadian rhythm, leading to a delay in melatonin release, which contributes to sleep deprivation and moodiness.
