Adolenscence
Adolescence is a time of significant growth and development inside the brain and extensive brain remodelling happens during this time, and it continues until the child is in their mid-20s. Brain change depends on age, experience, and hormonal changes in puberty.
The main change is that unused connections in the thinking and processing part of the child’s brain (called the grey matter) is ‘pruned’ away. At the same time, other connections are strengthened. This is the brain’s way of becoming more efficient, based on the ‘use it or lose it’ principle.
