In this interesting and informative article, Joel Nigg, Ph.D. maps the regions of the brain that control attention, impulsivity, and emotion, and explains why scientists are studying the “white matter” connections between these circuits. He discusses Bottom-Up Brain Signaling (response to sensory input — what you see and hear — that immediately trigger attentional capture or emotional reaction) and Top-Down Brain Signaling (response to internal signals based on goals, learning, or what you want to be doing.) In neurotypical people, there is a balance, but in people with ADHD the top-down signals are relatively weak.
