When your students say, learning hurts their brain, believe them…

New research reveals that the process of remembering something long-term comes at a cost – specifically, inflammation in the brain and DNA damage in nerve cells, as the memories get ‘fused’ into neurons and stored.

But our findings suggest that inflammation in certain neurons in the brain’s hippocampal region is essential for making long-lasting memories."
