"From a young age, the average, typical person's brain networks get moulded by intensive interaction with people and the mutual environmental factors,” says Hahamy in the press release. "Such shared experiences could tend to make the synchronisation patterns in the control group's resting brains more similar to each other. It is possible that in ASD, as interactions with the environment are disrupted, each one develops a more uniquely individualistic brain organisation pattern."

This strikes a chord in me...
It seems to me that it might be a case of neuroplasticity at work in some areas...
And atrophy in others...

An argument for the belief in progressively greater organisational change as a result of age/experience...
Could/would support the argument that an initial neurological difference provides the catalyst for this progressive divergence...

Hello Goldfish, according to the article the scans of NT brains show a pattern where as the ND scans do not have any comparable patterns. If you did arrange a scan and analysis, at whatever cost, the only result you could possibly achieve is to theoretically define either NT or ND. It would still not prove that you have a specific condition. I would save the money for something more constructive personally.


I comprehend how to interpret the results. Not NT is a significant result. It'll be especially worth while doing if I can manage to get it done for free or very inexpensively/in trade.


I don't see anything in the article to suggest that they are even claiming that. They report that they see a pattern emerge from many scans of NT brains, not that every NT brain is recognizable by it's pattern. They report that no pattern emerged from a scan of many autistic brains, not that no autistic brains were similar to any particular pattern.

Given what was described, there might be overlap between some of the autistic brains and the range the constitutes the NT pattern and there might be NT outliers that don't really fit the pattern.

I see nothing in these results to suggest that a brain scan is going to be able to determine that person is NT or ND.

I know you are literate and can think critically.

If there's a standard NT pattern that Most peoples' brains follow, and my brain's connective tissues don't follow it, then I'm not likely NT now, am I?

Connect the dots.. it's really not that difficult.

The existence of statistical tends showing up in aggregated scans of many people can't necessarily be shifted into reverse to diagnose an individual. There are studies of the volume of anatomical structures in the brain for various conditions, usually done with large numbers of people because the differences for each individual is so small. In that case, the predictive power will be low or even non-existent.

Also, people often forget that to diagnose a condition that affects 1% of the population requires a test much more accurate than 99% (IIRC, at 99% half of the diagnoses of a 1% condition will be false).

That is a naive and simplistic view of what they mean by pattern, as explained by Apple_in_my_Eye. As for connecting dots, this isn't a connect the dot drawing, it's neurobiology, topology and statistical science and it's really pretty complicated.

I understand that you would very much like it to be possible, but no one has reported that it is. If they did it would be very big news. Maybe that's coming soon, but I didn't see it in the write ups of this study.

While I disagree with a couple of you, it doesn't really matter what any of us think. When I have time I'm going to email the people responsible for this study and ask a few pertinent questions and see what they have to say about it.

The direct approach is sometimes best. Good luck.
