Neuroimaging in Cognitive Research: What fMRI, EEG, and PET Scans Reveal About Nootropics
Your brain runs on electricity and chemistry, but until recently, scientists could only guess at what happened inside your skull when you took a nootropic. They’d measure reaction times, memory scores, and attention spans, but the actual neural mechanisms remained hidden. Then neuroimaging cognitive research changed everything, turning the brain from a black box into…
