Brain Implant Restores Memory to Cocaine-Addled Monkeys
A team of researchers from three universities have succeeded in creating the first device that boosts the brain power of primates. In the study, five rhesus macaques were trained to complete an image-matching task. Each was shown one photo, and then asked to select the same photo from a larger pool of images. Using a tiny probe inserted into the monkey’s cerebral cortex, a computer recorded and analyzed the neural signals being sent when the primate was studying the first photo and when it made the “right” decision in the game. Over the course of two years, the monkeys acquired a 75% proficiency in this task.
