The brain abnormalities characteristic of tuberous sclerosis may begin early in development and involve malfunctioning of neuronal precursors, according to studies of two different mouse models of the disorder published in October.

Altered function of a brain receptor may help explain the why infection during pregnancy raises the risk for schizophrenia in the offspring, according to an unpublished rat study presented at the 2011 Society for Neuroscience annual meeting in Washington, D.C.

Scientists are analyzing more than 7,000 studies of functional magnetic resonance imaging to refine the role of various regions in the brain, according to unpublished work presented Monday at the 2011 Society for Neuroscience annual meeting in Washington, D.C.

A well-studied mouse model of autism has a smaller-than-normal volume in several autism-associated brain regions.

Researchers have defined anatomical boundaries that minimize errors in brain-imaging measures of the amygdala, a region involved in emotion processing.

Mice lacking a copy of SHANK3, a gene associated with autism and intellectual disability, show marked improvements in brain signaling after being treated with insulin-like growth factor 1, according to unpublished findings presented Saturday at the International Congress of Human Genetics in Montreal, Canada.

Three common laboratory chemicals are all scientists need to create see-through brains ideal for visualizing complex neural circuits.

Mice lacking a gene that regulates an important signaling pathway in the central nervous system have severe autism-like social deficits, including little interest in nurturing their offspring and problems with learning and memory.

Methylation marks were thought to be permanent features of the genome, but a new study challenges that idea.

Probiotic bacteria alleviate stress in healthy mice and modify the expression of receptors for a chemical messenger that inhibits signaling in the brain.
