They located no considerable change from the suggest activation due to modafinil or placebo, Nevertheless they discovered a powerful destructive correlation (auditory r = −0.74; visual r = −0.76) concerning cortical activation in advance of modafinil and cortical activation immediately after modafinil for individual topics. The fact that modafinil increased cortical activation in topics with small cortical activation and diminished it in topics with substantial cortical activation suggests that its results are certainly not unilateral but are a perform of baseline cortical activation and its consequences are modulatory and regulatory rather then augmentative.
