A few days ago I posted about a study that indicated the more formal education you received early in life indicated how soon you might show symptoms of dementia (see Another Reason To Stay In School — It Lowers Dementia Risk).
A report on the same study in Scientific American today also says the researchers found that the more education you received, the heavier your brain becomes:
As she and her colleagues discuss in the study, the more substantial heft might be due to an increased number of synapses as a result of education—and a more stimulating, healthier mental life thereafter.
The work of Carol Dweck and others have shown that learning does physically affect the brain, and many teachers, including me, have used that research in lessons.
This study may be another indication of that growth.
