Pruning In Teenage Brains

Imagine a gardener, pruning trees and plants of its useless limbs. This process of removing unneeded material may seem unnatural or man-made, yet, it occurs in the brain during the teen years. Pruning, or the removal of unused connections in the brain, is essential to brain development. Gray and White matter are also essential, which store information and make new neuron connections. Furthermore, new studies show that neuron connections are actively being made throughout teen years. The teenage brains goes through many processes, such as pruning, developing grey matter, and making new connections. Teenagers may seem like they purposely make bad decisions and want to annoy people; however, it is not completely their fault.
Pruning usually takes place between the ages of 11 and 14. During this process teens may lose a great amount “of the connections between cells of the brain that enable him or her to think clearly.” This is part of the reason teens may seem to not be able to make good decisions (Boyd). The connections that are weeded out are the ones that are not used, or unneeded (Giedd). Though a loss of these connections may seem bad, it is a good thing. Pruning speeds up information processing in …show more content…

Gray matter, an outer layer of the brain that stores and processes information, peaks at age 12. This large amount of gray matter means that the brain is constantly learning and absorbing information “throughout childhood [and] continues to do so through adolescence” (Hamalainen). White matter, made up of a fatty white substance, “insulates nerve cells [helps] speed up connections.” White matter does not make all new connections at one time, but once the brain is in the teen years, white matter has already made many important connections in the brain (Jensen). Teens are still able to study for tests or use their motor skills, however, they don’t have all the same connections as an
