- Protocol
- piracetam vs placebo; movement-related brain potentials
Key findings
- No side effects reported with single or repeated dosing
- No difference from placebo in task performance (already optimal) or muscle activity
- The readiness potential became a positive shift with a single dose and grew with repeated dosing
- Repeated dosing enlarged and sped up the skilled performance positivity component
Healthy children took either piracetam (a drug proposed to aid learning and memory) or placebo in random order, with a three-week washout, in a triple-blind design testing both a single dose and longer-term dosing. Movement-related brain potentials were recorded while they performed a skilled motor-perceptual task. Task performance and muscle activity did not change, but several brain potential components did, suggesting the drug altered the brain processes behind the task even though behaviour was already at ceiling.
