Here is an interesting research article about two regions of the brain that fail to connect when children with ADHD attempt a task that measures attention, according to researchers at the UC Davis Center for Mind and Brain at the M.I.N.D. Institute.
Here is some of the information from this very interesting article.
"This is the first time that we have direct evidence that this connectivity is missing in ADHD," said Ali Mazaheri, postdoctoral researcher at the Center for Mind and Brain. Mazaheri and his colleagues made the discovery by analyzing the brain activity in children with ADHD.
The researchers measured electrical rhythms from the brains of volunteers, especially the alpha rhythm. When part of the brain is emitting alpha rhythms, it shows that it is disengaged from the rest of the brain and not receiving or processing information optimally, Mazaheri said. "The brains of the children with ADHD apparently prepare to attend to upcoming stimuli differently than do typically developing children," he said.
Children with ADHD did improve their reaction times when properly cued, but they don't seem to allocate resources as efficiently, Mazaheri said.
This is the first evidence from brain electrical patterns for a functional disconnection in cortical attention systems in ADHD, he said. Current definitions of ADHD are based only on behavior.
