Interesting study that shows the correlation of dopamine, hyperactivity, learning ability, ADHD and how fruit flies have emotions and the ability to learn.
In the article below you will learn from David Anderson that ADHD and other common brain disorders are “actually disturbances in the neural circuits that mediate emotion, mood and affect.” In that respect it makes sense to me to listen to the explanations of Ron Davis. He believes that ADHD is often caused when students are not interested in the subject and/or don’t understand what the teacher is saying. Their perception is altered by that combination of boredom and confusion and causes disorientation. Disorientation speeds up the internal clock, slowing down external time. Their sense of balance and movement is also affected and distorted – and movement (hyper activity) helps them to restore the balance between internal and external differences: “emotion, mood and affect” are at work. The affect if not moving would be similar to motion sickness. The solution would be to give the ADHD individual the tools to restore orientation and control their behaviour themselves, without drugs. Adderall, Ritalin and other amphetamines aim to increase the amount of dopamine that is released into the brain. Orientation does the same, yet without amphetamines.
