Patterns of brain activity in people with autism are unusually consistent over seconds—and even years, two new studies suggest.

One study shows that patterns of connectivity remain stable in autistic adolescents, whereas they tend to change and specialize in controls. The other study found that connections remain fixed longer in people with autism than in controls. Both focused on so-called “functional connectivity,” the extent to which the activity of pairs of brain areas is synchronized.

Together, the studies may help untangle seemingly contradictory findings on connectivity in autism: reports of both underconnectivity and overconnectivity in the brain.

“Maybe the primary abnormality isn’t just that things are too weakly or strongly connected, that it has more to do with the timing of brain connections,” says Jeff Anderson, professor of radiology at the University of Utah, who led the second study.

The studies also highlight the importance of measuring brain activity over varying time periods and at different ages.

Researchers who home in on a single age may overlook differences that appear over time, says Mirella Dapretto, professor of psychiatry and biobehavioral sciences at the University of California, Los Angeles, and lead researcher on the adolescent study. “You miss some of the bigger picture.”

Studying brain activity over time provides a rare window into the development of connectivity.

“This is one of the only papers I’ve seen so far that tries to tackle that by doing it longitudinally,” says Lucina Uddin, associate professor of psychology at the University of Miami in Florida, who was not involved in the work. “You see that there may be a different developmental trajectory in autism.”

Tracking teenagers

Dapretto and her team scanned the brains of 16 adolescents with autism and 22 controls at rest when they were 11 to 14 years old, and again about three years later.

The researchers measured connectivity among three brain networks thought to be altered in autism: the default mode network, which plays a role in self-reflection; the salience network, which directs attention; and the central executive network, which governs decision-making and
