People who are blind really do have enhance abilities in their other sentiency , according to a new , small study . The research used detailed brain scan to compare the brains of people who were blind to the brain of the great unwashed who were not blind .
The study involved people who were either suffer unsighted or became unreasoning before years 3 . The scans indicate that these individuals had heightenedsenses of hearing , smell and touchcompared to the citizenry in the subject field who were not unsighted .

In addition , the scan reveal that people who are blind also experience enhancements in other areas , including in their retentivity and language abilities , according to the study , published today ( March 22 ) in the journalPLOS ONE .
Such mentality change uprise because the mastermind has a " pliant " timber , meaning that it can make new connections among neuron , the discipline said . [ 10 Things You Did n’t Know About the Brain ]
" Even in the cause of being deeply unsighted , the brain rewires itself in a manner to utilize the data at its disposal so that it can interact with the surroundings in a more effective manner , " older study author Dr. Lotfi Merabet , the director of the Laboratory for Visual Neuroplasticity at Schepens Eye Research Institute of Massachusetts Eye and Ear , said in a statement .
A study participant in a magnetic resonance imaging (MRI) scanner.
The finding suggest that " there is tremendous potential for the mastermind to adjust , " Merabet said .
In the bailiwick , the research worker perform brain scans on 12 people who were unsighted and 16 hoi polloi who were not unsighted . All of the somebody in the study who were unreasoning were " extremely self-governing travelers , employed , college - educate and experienced Braille reader , " the research worker note .
psychoanalyse the head scans , the research worker found that there were " extended morphological , structural and functional"differences in the mastermind of the peoplein the report who were blind compared to the wit of the citizenry who were not blind .
" We observed significant changes not only in the occipital pallium ( where vision is processed ) , but also area implicated in memory , language processing and sensory motor function , " lead study author Corinna Bauer , a scientist at the same institution , said in a statement .
Some of these changes were related to connective in the brain , the scientist observe .
For deterrent example , the researcher found difference in " ashen matter connexion and useable connection " in the people who were blind compared with those who were n’t , Bauer assure Live Science . White issue connections are the physical " highway " within the wit through which information flows ; operable connections can be thought of as how well head regions transmit with one another , Bauer said .
The mass who were blind had fewer connection between thevisual parts of the brainand other areas of the mental capacity , " compare with the people who were not blind , Bauer said .
But " there are also areas of the head , link up with other skunk , that are more co-ordinated , " such as surface area involved with language and auditory processing , she said . By strengthen the connections among these areas , it come out that mind may be compensating for blindness , she said .
