I've long held an interest in neuroscience, as well as come from a psychology/mental health educational background, so terminology and etc was familiar. What I found to be exceptional was Todd Murphy's clear explanation relating the brain functionality and the effects from long term meditation. This video was helpful to gain more understanding of the physio alterations to the brain in relationship to the stages of Enlightenment.
Also, this information seems relevant to a few current topics on the DhO boards.
