To review:
Impulsive and erratic behavior, symptom of ADHD (attention-deficit/hyperactivity disorder), which can be resolved with the help of some drugs. The administration of such drugs results in the stimulation of brain neurons. The neural basis behind this effect is to be explained.
Introduction:
ADHD is a neural disorder in which a person finds difficulty to pay attention and control their impulsive behaviors. The patients are also sometimes restless and constantly active, and do not sit still for a longer time than their usual counterparts. It is normally seen in childhood but adults can also get affected by this disorder. ADHD is not fully curable, although there are certain drugs that can reduce the ADHD symptoms.
