I’ve written a lot about how learning in general strengthens the brain and reading’s effects on the brain (see The Best Resources For Showing Students That They Make Their Brain Stronger By Learning).

In addition, I’ve written a lot about recent research finding how handwriting in particular helps brain development (see The Best Resources For Learning About Handwriting & Learning).

Now, I’m looking for research documenting how writing of any kind might strengthen the brain.

Does anyone have suggestions?
