The Brain

A growing body of evidence suggests that autism involves atypical communication between brain regions, but how and where in the brain this plays out is unclear.

A new magnetic resonance imaging machine has the power to reveal the brain’s structure and activity at unprecedented resolution.

Two imaging techniques together reveal architectural features of the brains of preterm infants.

The brains of people with autism have unusually strong connections in some regions and weak ones in others.

The brains of autistic children show few differences from those of children with attention deficit hyperactivity disorder, or even of controls.

Autism BrainNet, a repository of postmortem brains, has new tissue from more than 150 brains, including 59 from people with confirmed or possible autism.

Problems with the minute ‘factories’ that yield energy for cells — the mitochondria — may contribute to learning problems and other traits of fragile X syndrome.
