J Neurosci: how does the brain reprogram "unused" areas?

September 24, 2019 / biourn / -- according to a new study recently published in the Journal of neuroscience, the "visual" cortex is activated in a similar way during listening tasks in adults who are "blind" at birth From the perspective of developmental biology, these results answer the question of how the key parts of the brain "Transcend" the influence of anatomical structure on brain function Previous studies have found that the "visual" cortex of blind people will be recruited by other signals to function, but it is not clear whether this new use is consistent or individual In response, loiotile and others from the Department of brain science and psychology at Johns Hopkins University used fMRI to compare how the brain auditory and visual cortex of blind and blindfolded participants were activated when listening to the audio clip in the movie (image source: www Pixabay Com) the results show that 65% of the visual cortex has similar activation characteristics when blind people listen to film clips When a sentence is played in random order or a track is played from the back to the front, the similarity becomes low, indicating that the region is used for a higher level of signal processing All in all, these results show that there is a "basic" tissue in the brain, which determines how the visual cortex is reused in the blind, and the use of this random use is not random How the brain returns unused regions: natural audit stories synchronize "visual" cortices across purposely blind but not seen individuals, jneurosci, DOI: 10.1523/jneurosci.0298-19.2019
