I might be wrong, but isn't it reasonable that when the brain is focused on something the different areas of the brain will be coordinated, communicating with each other in order to accomplish their common objective.<br /> When the brain is scattered the different areas are pursuing different tasks/objectives, and they are not communicating properly with each other, because they are in a kind of fight for gaining the other parts collaboration for their cause, which causes their cross messages to lack coordination given that everybody is sending requests and no acknowledge or reply to that requests are sent.</p> JanetK: Thanks Mariana. I think your right. But the article seems to be making the point that the prefrontal cortex is the area that is initiating the synchrony and therefore presumably initiating the communication. This would imply a top-down rather than a bottom-up control of the focus of attention. I tend to treat each piece of data as a vague, tentative indication of something and it is only when a number of studies with different methods and perspectives point to the same 'something' that I start to think it is probably so. Yes, gamma waves are probably either the sign of consciousness or attention or both. But where they start and what they communicate is another matter – not very clear at all. Very interesting article. I might be wrong, but isn’t it reasonable that when the brain is focused on something the different areas of the brain will be coordinated, communicating with each other in order to accomplish their common objective.
