October 9, 2008 Brain scans for the prosecution Greg Freiherr Those of us who recognize our frailties -- the prejudices and biases that creep almost imperceptibly into our decision making -- would welcome a quantifiable means for ensuring that those decisions are best made. Last month, prosecutors successfully convinced a court in Mumbai, India, that a scan that records activity in distinct areas of the brain can be such a measure. On the basis of a "Brain Electrical Oscillations Signature"…
