Much like tapping a patient on the knee to gauge a physical reaction, trans-cranial magnetic stimulation triggers activity in specific areas of the brain through a charged...

Scientists Read Subjects' Location From Brain Scans

(Newser) - Decoding part of the complex system used by the brain to store memories has allowed scientists to determine a person’s location by looking at brain scans, Wired reports.
