Is there anything we can't learn from drugged up rats? Researchers at Wake Forest University and the University of Southern California used a group of medicated rodents to demonstrate a method by which memory can be restored with the flick of a switch. The rats were outfitted with tiny, rat-sized electrodes and exposed to pharmacological substances, which caused them to forget the connection between pushing a lever and getting water. By turning the electronic switch on, the scientists restored the rats' memory of the task -- turning it off made them forget again. The next step in the process is testing the experiment out on primates and perhaps some day utilizing the research to benefit victim
