Using functional magnetic
resonance (fMRI)
imaging, Schipul and Just found that the brain activation of ASD individuals was slower to become familiar with the pattern they repeatedly saw, — meaning their brains failed to register the «oldness» of the patterns to the same degree that the control participants
did.

For example functional magnetic
resonance imaging (fMRI), children with a history of preschool - onset depression demonstrated distinct patterns of brain activation, which were similar to those of adults with depression.34 Other research documents that DSM - IV criteria for depression
do not adequately capture the disorder's course in preschool - aged children.35 Similar to the heightened awareness regarding preschool depression, evidence suggests that young children can also suffer from post-traumatic stress disorder when age - adjusted diagnostic criteria are employed.36
