The research, which was published 24 December in Frontiers in Neuroinformatics, included nine children with Asperger syndrome, aged between 6 and 14 and ten age-matched typical children. The researchers scanned their brains using magnetoencephalography (MEG), a noninvasive method that doesn’t require lying in a noisy, confined space as magnetic resonance imaging does.
That method was important for this study because the researchers wanted to capture the brain’s activity when it was receiving as little external stimulation as possible. During the data collection, the children were in a magnetically shielded room, with the MEG recording device over their heads.
The children had to lie still with their eyes open. That raises the question of whether their brains were actually at rest — but Galan says even if the children weren’t completely without external stimulation, the results suggest that in the same boring situation, people with autism process more information than their typical peers.
“Our results fit very well with the intense world theory, which describes autism as a disorder resulting from hyperfunctioning neural circuitry, which leads to a state of over-arousal,” says lead researcher Roberto Galan, assistant professor of neuroscience at Case Western Reserve University in Ohio.
