Dyslexia can cure? French scientists: LED high-speed flash lamp treatment

Read and write barriers (dyslexia) is the problem of many students, may also be one source of unsuspecting parents blame their children. Often, the writing is similar to the shape of the letter confusion and other symptoms, general cognition is due to congenital anomalies caused by brain structure. Through training can be improved, but there has been no solution can cure.

But the French class scientists say they may have found a reason to write read physiological disorder answers hidden in patients with eyes, and think of a relatively simple method of treatment.

Dyslexia answers hidden in the eyes

With the left and right handers, human eyes are also divided into primary and secondary, most of them per capita to dominant right eye (dominant eye). Look at something, the primary and secondary eye received a slightly different image. Among the dominant eye will produce better image quality image, the other eye is a bit poor, the brain "integration" will produce a single image.

In general, the cone is responsible for receiving image signals (cone, cell) in the main view in cylindrical array, the other eye is irregular arrangement. Two French scientist Flook (Albert Le Floch) (Guy Ropars) and ropars in biological research on "Proceedings of the Royal Journal Society B published" found that reading cones to write the same disorder eyes cylindrical arrangement, make eyes to each other for the main role in eye, brain produces the so-called "mirror the error in the chaos" (mirror errors), which is similar to patients with visual confusion, confuse "B" and "d" shape is similar, but in the opposite direction to the case of letters.

Read and write disorder problems, because there are two identical images confuse the brain, as long as the mean offset of one image can solve the problem.

The researchers found that when both images transmitted to the left and right brain patients, there was about a second lag, so they come up with a LED high-speed flash lamp using an invisible, eliminating overlapping images that troubled patients. As a result, the brain is only one image, so that they can be read properly.

Professor at the University of Oxford and the British Dyslexia Association Consultant (John Stein) said, Stein, this study is interesting, because the past studies on dyslexia little focus in the visual aspects of patients; at the same time to highlight the dominant eye in the importance of the brain receives images. But this is not in want of perfection, on account of the cone cells arranged in different causes.

Dyslexia is the most common global learning problems, affected by the number of 3% to 7% Public opinions are divergent., there are people, also there is a saying that a population of up to 20% different degrees of dyslexia symptoms.
