I send you this link just because I like the term Hippocampodrome. It is my word of the day. And, if I remember that I first saw it with a white background, I am actually exercising! Yippee!
I want a way to exercise the hippocampus. So far, I have been doing Google searches for phrases like 'hippocampus activation' in order to discover research. Particularly, I have been looking for research that shows increased neuronal activity or blood flow to hippocampus using fMRI or PET. My theory is that, if you practice the things which increase activity in the hippocampus, you will develop your hippocampus. I have good basis for this theory, I believe. Here is what I have found so far.
