It's not known whether people with autism have more or less
connections in parts of their brains that normally work in together.
Now a new study
states the lack of common ground in this area reflects the fact that people
with autism have connections that are uniquely their own.
According to the
scientists, the research could help lead to better diagnosis of autism and
'It opens up the
possibility that there are many altered brain profiles all of which fall under
the umbrella of 'autism','' said Dr Marlene Behrmann at Carnegie Mellon
University in Pittsburgh.
studied data taken from functional magnetic resonance imaging (fMRI).
studies are important because that is when patterns emerge spontaneously,
allowing us to see how various brain areas naturally connect and synchronise
their activity," said Avital Hahamy, a Ph.D. student in Dr Weizmann's
participants' brains had similar connectivity patterns across different
individuals. However, those with autism tended to display much more unique
the patterns in the autism and control groups could be explained by the way
individuals in the two groups communicate with their environment.
Mr Hahamy said,
"From a young age, the average, typical person's brain networks get moulded by
intensive interaction with people and the mutual environmental factors."
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.
