Fitness Shapes Teen Brains

A novel study finds a link between childhood physical fitness and cerebellar grey matter volume in adolescents. The research, part of the FitBrain study, shows that adolescents with better neuromuscular fitness had larger Crus I grey matter volumes, important for cognition and learning. However, the study also found that better cardiorespiratory fitness was associated with smaller overall cerebellar volume, with gender-specific differences noted.

Teen Binge Drinking Tied to Adult Brain and Neurotransmission Changes

Young adults who heavily consumed alcohol during their teenage years exhibited thinner cortical gray matter and modified neurotransmission. Utilizing MRI and TMS-EEG technology, the researchers identified lower gray matter thickness and increased N45 potential, indicative of inhibitory GABA and excitatory glutamate neurotransmitter activity. This study underlines the long-term, detrimental impact of adolescent heavy drinking on adult brain structure and function.

How Prozac Increases Brain Plasticity

Fluoxetine (Prozac), a common antidepressant, was found to enhance the erasure of learned fear responses and facilitate spatial pattern learning in mice. The study also found the TrkB receptor in PV+ interneurons plays a crucial role in these effects, which may offer new possibilities for the development of psychiatric treatments targeting brain plasticity.
