The Brain—Information about the Brain

The Brain—Information about the Brain 1 Introduction “I think, therefore I am.” —René Descartes, 17th-century philosopher Few of us question the crucial importance of the brain.
It is controversial whether the adult primate early visual cortex is sufficiently plastic to cause visual perceptual learning (VPL). The controversy occurs partially because most VPL studies have examined correlations between behavioral and neural activity changes rather than cause-and-effect relationships. With an online-feedback method that uses decoded functional magnetic resonance imaging (fMRI) signals, we induced activity patterns only in early visual cortex corresponding to an orientation without stimulus presentation or participants’ awareness of what was to be learned. The induced activation caused VPL specific to the orientation. These results suggest that early visual areas are so plastic that mere inductions of activity patterns are sufficient to cause VPL. This technique can induce plasticity in a highly selective manner, potentially leading to powerful training and rehabilitative protocols.

Scientists say they're getting closer to Matrix-style instant learning SExpand What price effortless learning? In a paper published in the latest issue of Science, neuroscientists say they've developed a novel method of learning, that can cause long-lasting improvement in tasks that demand a high level of visual performance. And while the so-called neurofeedback method could one day be used to teach you kung fu, or to aid spinal-injury patients on the road to rehabilitation, evidence also suggests the technology could be used to target people without their knowledge, opening doors to numerous important ethical questions. According to a press release from the National Science Foundation: New research published today in the journal Science suggests it may be possible to use brain technology to learn to play a piano, reduce mental stress or hit a curve ball with little or no conscious effort. Scientists say they're getting closer to Matrix-style instant learning
