| Research Abstract |
Recently, both young and old people do not have enough patience. There are two kinds of patience ; one is to give up immediate small reward for later and much larger reward, and the other is to inhibit predominant response tendency to follow the social or moral rule. The prefrontal cortex plays important roles in the control of patience behavior. Primate prefrontal neurons show activity changes in relation to patience behavior. Methylphenidate (Ritalin) is known to control patience behavior in ADHD patients. Application of this drug to the monkey induced improvement in self-control behavior as well as inducing increase in dopamine release in the prefrontal cortex and striatum.
