Subject line is a bit short...
Andy's summary
When there is an incentive to do a test, MPH will help an adhd person to stick to that task more effectively due to the well known effect of higher dopamine productive via MPH. When the brain is not given a high enough incentive, the drug does not help to produce more dopamine.
That's quite scary because if I understand correctly, the MPH will only have it's effects when the brain calls for it. Just like speedstep/cool n quiet/ power on demand systems on computers/graphics cards....
Therefore, if the duck floats, then it must be made of wood and it's a witch therefore meaning that adders are literally human computers.
DOH! I am tired and am now just spouting random sentences to keep myself amused :/
It's that naughty executive function again, is it? Damn brain, why won't you do as you're told!
Jeez, sometimes I get these articles, but when I try to understand them fully it's a real argh on my brain. Just makes me tired and groggy.
Oh, here's the article .....
Here is a quote from the extract of the link at the bottom.
QUOTE
The authors compared the effects of methylphenidate during an academic task (solving mathematical problems with monetary reinforcement) and a neutral task (passively viewing cards with no remuneration). (LOL, money talks eh?)
Methylphenidate, when coupled with the mathematical task, significantly increased extracellular dopamine, but this did not occur when coupled with the neutral task. The mathematical task did not increase dopamine when coupled with placebo.
The significant association between methylphenidate-induced dopamine increases and the interest and motivation for the task confirms the prediction that methylphenidate enhances the saliency of an event by increasing dopamine. The enhanced interest for the task could increase attention and improve performance and could be one of the mechanisms underlying methylphenidate's therapeutic effects. These findings support educational strategies that make schoolwork more interesting as nonpharmacological interventions to treat ADHD.
