Another excellent post and video. This helps me understand why when my father had his stroke certainly behaviors where alters but there was three other gentlemen in his room and each had different behaviors had changed. I never understood that but you're video explained that the brain is divided into different areas that control certain aspect of your behavior for instance memory or communication etc. I am really looking forward to tomorrow's post on how to maximize my brain performance. Where do you come up with such interesting topics. Thanks for sharing....appreciate.
