Failures teach nothing, as the brain

researchers say that the mind is more likely to repeat its success in terms of committing to modify errors. Scientists
Massachusetts Institute of Technology (MIT) say that neurons are only able to learn from experience when things are done correctly and not when it fails. It informs a press release issued by the university.
The research, supported by the American Institute of Neurological Disorders (NINDS), took snapshots of physical reaction of neurons after hit and error, respectively, to give some answers.
The scientists, led by Dr. Earl K. neuroscience Miller noted that the correct answer, the neurons increased their activity and improved brain function, making it easier than following answers were also correct.
the contrary, when responding in the wrong manner, decreased neuronal behavior, the following responses also tended to be wrong and made it difficult for the brain to change its operation, since the neurons decreased the amount of electrical impulses sent.
Coupled with a greater amount of electrical activity sent by neurons after giving a correct answer, the researchers found that had greater amounts of information in those signals. "This could explain why neuronal level seem to learn less from our mistakes than our successes," concluded Miller. News published in
