Quick follow up to my earlier post. Via RealClear Science:

Changes can start to occur in adolescence. Reviewing the scientific literature in 2018, researchers from the University of Southern California found that for teens aged 15-18, regular exercisers tended to have larger hippocampal volumes as well as larger rostral middle frontal volumes compared to healthy matched control teenagers. The hippocampusis most commonly associated with memory and spatial navigation, while the rostral middle frontal gyrus has been linked to emotion regulation and working memory. Studies suggest that these structural changes translate to improved cognitive performance and better academic outcomes.

But what about people our age?

The researchers recruited older African Americans, all previously sedentary, to complete twenty weeks of twice-weekly cardio-dance exercise classes held at local churches and senior centers. As compared to the control group comprised of community members of similar age and background who did not exercise, those in the program showed significant improvements in dynamic brain connectivity (or “neural flexibility”) in their hippocampus and surrounding medial temporal lobe, as measured using resting-state functional MRI.

Check out the RCS article here. Then see if my earlier article makes sense.
