The principal sum callosum is a wide bundle of over 200 million axons which link the right and left hemispheres of the learning ability . During development , this important bridge is not always formed correctly and can either be malformed or partially or whole scatty . This shape is referred to as agenesia of Corpus Callosum ( AgCC ) . A group of researchers have instal alink between AgCC and autism . The announcement comes from the laboratory of Ralph Adolphs of Caltech , and the paper publish in the journalBrain .

Though sever the principal sum callosum can relieve raptus in those with grave epilepsy , a rarified defect which first presents during the first trimester of pregnancy leaves some without that structure , or with one that was not entirely or right formed . AgCC typically is n’t black , but those with the condition may have delayed developmental milestones , social difficulties , memory topic , and/or cognitive impairments . These are also many of the same symptoms of autism .

This is n’t the first clock time aconnection between AgCC and autism has been made , but this is the first clock time that both groups have been at once compared . Over the span of about 10 yr , the researcher had participant from both groups complete task based in societal behavior and nonfigurative thinking . Some of these experiments were record , allowing researchers to go back and watch the tapes again to analyse the behavior . In addition to social part , they also measure intelligence .

" When we made detailed comparisons , we establish that about a third of people with AgCC would meet diagnostic measure for an autism spectrum disorderliness in terms of their current symptom , " say Lynn Paul , go source of the study , in apress release .

There are differences between the two group , however . While symptoms of autism usually present early on in life , those with AgCC do n’t start showing symptom until the pre - puberulent years when the brain undergoes developmental change . While being a pre - adolescent is typically unenviable enough , those with AgCC are more likely to expose social cumbersomeness .

This info has research worker and physicians in a good billet to start out a novel line of enquiry . As ultrasound technology has gain , it has been made possible to diagnose AgCC while the baby is still developing . This would permit research worker to supervise behaviour and brain morphology through MRI throughout life and compare it to the timeline of a nestling with autism .

" If we can place citizenry with AgCC already before birth , we should be in a much better posture to render intervention like social skills training before problems arise , " Paul go on in thepress press release . " And of course from a inquiry perspective it would be tremendously worthful to set out canvas such person early in sprightliness , since we still recognise so lilliputian both about autism and about AgCC .
