Have you ever seen an "active" image of the human brain, taken with a scanner which monitors the glucose usage of neurons (a radiolabeled isotope of which having been previously injected)? The subject of the scan is instructed to think of a particular subject, and corresponding portions of the brain "light up." It should be a simple extension of the method to couple this machine with a computer-controlled "ultrasonic knife" (an instrument used for the destruction of brain-tumors through the usage of intersecting ultrasonic wave-paths, by surgeons.) It should be a simple matter to isolate the neural home of an unpleasant memory or character trait and physically destroy it without harming too much surrounding tissue. The resultion of the ultrasonic knife may prove a problem, however. It may also be a false assumption that such things reside in particular clusters of neurons.-- dsm, Dec 31 2000 A targeted therapy http://www.celsion.com/08082000.htmlUses phased array microwaves instead of ultrasound--great technology for delivering liposomes to an selected area.

AND, those neurons are likely also involved in other things, too.-- rebekkahshiri, Jun 14 2001 You first.-- egnor, Jun 14 2001 random, halfbakery
