Siblings of schizophrenia patients display subtle shape abnormalities in brain

Subtle malformations in the brains of patients with schizophrenia also tend to occur in their healthy siblings, according to investigators at the Silvio Conte Center for the Neuroscience of Mental Disorders at Washington University School of Medicine in St. Louis. Shape abnormalities were found in the brain's thalamus.

Poor recognition of 'self' found in high functioning people with autism

Contrary to popular notions, people at the high end of the autism spectrum disorder continuum suffer most from an inability to model "self" rather than impaired ability to respond to others, said Baylor College of Medicine researchers in a report that appear in the journal Neuron.
