A pivotal period in human brain and behavioral development occurs in the first years of life.
These years are normally characterized by a degree and variety of neuroanatomical change …

Autistic symptoms begin in the first years of life, and recent magnetic resonance imaging
studies have discovered brain growth abnormalities that precede and overlap with the onset …

Autism is a neurobiological disorder that is diagnosed through careful behavioral
assessment in early childhood. In this paper, we review recent studies that have attempted …

Studies of infant siblings of older autistic probands, who are at elevated risk for autism, have
demonstrated that the defining features of autism are not present in the first year of life but …

Magnetic resonance imaging (MRI) of brain structures and function is uniquely suited to

Postmortem neuropathological studies of autism consistently reveal distinctive types of
malformations, including cortical dysplasias, heterotopias, and various …

Although the neurobiology of autism has been studied for more than two decades, the
