Assessment
Primary outcomes
(1) fNIRS analysis
Comparison of frontal activation (oxy-Hb, deoxy-Hb and total-Hb, measured by fNIRS) before and after an acute clinical dose of MPH or placebo (90 min after MPH administration)
(2) Behavioral performance
Comparison of reaction time and percentage of correct response on Go/NoGo task before and after the acute clinical dose of MPH or placebo (90 min after MPH administration)
Key secondary outcomes
The response of continuous administration of MPH on ADHD rating scale and Questionnaire-Children with Difficulties

Results
There was no significant activation in the lateral prefrontal cortices examined before MPH intake. However, after MPH intake, significant MPH-elicited activation (oxygenated hemoglobin signal increase) was detected in the right lateral prefrontal cortex (LPFC) implicated with response inhibition functions. There was a large significant correlation between increases in task performance and activation in the right LPFC.
