Download Knowledge Directly to Your Brain
For the first time, researchers have been able to hack into the process of learning in the brain, using induced brain patterns to create a learned behavior. Its not quite as advanced as an instant kung-fu download, and its not as sleek as cognitive inception, but its still an important finding that could lead to new teaching and rehabilitation techniques.
Future therapies could decode the brain activity patterns of an athlete or a musician, and use them as a benchmark for teaching another person a new activity, according to the researchers.
Scientists from Boston University and ATR Computational Neuroscience Laboratories in Kyoto used functional magnetic resonance imaging, or fMRI, to study the learning process. They were examining the adult brains aptitude for visual perceptual learning, or VPL, in which repetitive training improves a persons performance on a particular task. Whether adults can do this as well as young people has been an ongoing debate in neuroscience.
Led by BU neuroscientist Takeo Watanabe, researchers used a method called decoded fMRI neurofeedback to stimulate the visual cortex. First they showed participants circles at different orientations. Then they used fMRI to watch the participants brain activity. The researchers were then able to train the participants to recreate this visual cortex activity.
