The second wave of synapse formation described by Giedd showed a spurt of growth in the frontal cortex just before puberty (age 11 in girls, 12 in boys) and then a pruning back in adolescence.

What part of the brain starts the puberty process?
the hypothalamus Puberty is the body's natural process of sexual maturation. Puberty's trigger lies in a small part of the brain called the hypothalamus, a gland that secretes gonadotropin-releasing hormone (GnRH).
What is a brain growth spurt?
Signs of Brain Growth Spurts in the Early Years New connections between brain fibers are growing, strengthening, or being trimmed away. During growth spurts, the brain is disorganized. New connections in the brain are more prone to misfiring and miscommunicating.
What are the two brain structures involved in triggering puberty?
You may see the earliest signs of puberty in this phase, like pubic hair, body odor, oily skin, and acne. Then, two small brain regions, called the hypothalamus and pituitary gland (pink), send messages to the reproductive organs, telling them to make sex steroids like testosterone, estrogen, and progesterone (blue).
What triggers the beginning of puberty?
Puberty has begun. The trigger for puberty in both boys and girls is the production of 'gonadotrophin releasing hormone' (GnRH) from a part of the brain called the hypothalamus. This hormone stimulates the pituitary gland to release two hormones, Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH).
Which part of the adolescent brain is developed first?
Scientists have identified a specific region of the brain called the amygdala that is responsible for immediate reactions including fear and aggressive behavior. This region develops early. However, the frontal cortex, the area of the brain that controls reasoning and helps us think before we act, develops later.
What happens to the brain during puberty?
Brain maturation occurs during adolescence due to a surge in the synthesis of sex hormones implicated in puberty including estrogen, progesterone, and testosterone. These sex hormones augment myelinogenesis and the development of the neurocircuitry involved in efficient neurocybernetics.
What does your brain do during puberty?
However, researchers have discovered that puberty not only changes your body, but also your brain. This is because puberty involves changes in hormones that also attach to your brain cells and change how the brain learns and grows. These changes are useful because they help shape the brain for new forms of learning.

This is because puberty involves changes in hormones that also attach to your brain cells and change how the brain learns and grows. These changes are useful because they help shape the brain for new forms of learning.
Can a boy hit puberty at 8?
But it's perfectly normal for puberty to begin at any point between the ages of 8 and 13 in girls and 9 and 14 in boys. There's not usually any need to worry if puberty does not start around the average age, but it's a good idea to speak to your GP for advice if it starts before 8 or has not started by around 14.
