I found this great post at Smooth Pebbles. It is a brief but well written article about the biochemical changes that take place in the brain of a jazz player while actually in the process of improvising! There is a cool picture (presumably obtained by some type of brain scanning device) that shows these changes quite remarkably! I always suspected that us jazz players were a little “off” in the brain! Anyway, check it out especially if you are somewhat science minded as I am. Enjoy.Stay tuned…Marty
