The elaboration of the sound in the autistic ones

Tenuous it marks them magnetic nell’ cerebral activity of the autistic children shows that they elaborate the sound and the language in a different way from the not autistic children. E’ how much turns out from a search lead near the Children’ s Hospital of Philadelphia and introduced to the conference anniversary of the Radiological Society of North America in course to Chicago.
LThe identification and the classification of these outlines of cerebral answer will be able to concur a more accurate diagnosis dell’ autism and to develop therapeutic approaches for the treatment of this disturbance.
” The children with autism answer more slowly with a fraction of second of the healthy contemporarys to the vocal sounds and the intonazioni” , he has said Timothy Roberts, that he has directed the search, conduct taking advantage of magnetoencefalografia (MEG), a technique already used for the study dell’ epilepsy that finds the cerebral magnetic fields own like l’ elettroencefalografia (EEG) of it finds the electric fields. ” It marks them cerebral electrical workers generate little ones you live magnetic whom they change with the feelings and the communication between the several areas of the brain”.
” Our hypothesis is that spoken and the other sounds arrive too much quickly for the children with distrurbes of the autistic phantom and that their difficulties nell’ elaboration of the sound can hinder the linguistiche performances and of comunication” , it has added Roberts.
When it comes introduced a sound, the MEG records a delay of 20 milliseconds in the cerebral answer of the subjects with disturbances of the autistic phantom regarding those normal schools. This delay indicates that the auditory process is abnormal in the autistic children and can carry to a cascade of delays and an overload of the successive processes of elaboration of the sounds and the spoken one.
Since the autism is introduced in a wide phantom of ability and disability works them, the ” firme” magnetic of the cerebral answer it could allow a more accurate diagnosis of the under type of autism of the single patients, and this also to un’ premature age, with a benefit for the timeliness of the participations.
