Rat study sniffs out vasopressin’s role in social behavior

by  /  7 May 2010

Neuroscientists have discovered a population of cells in the smell-perception area of the rat brain that express the hormone vasopressin. The study, published in Nature, begins to unpack the complicated molecular interactions of the hormone in the brain, which could lead to new autism treatments.

Researchers probe genetic overlap between ADHD, autism

by  /  22 April 2010

Attention deficit hyperactivity disorder (ADHD) and autism may have more in common than childhood onset and a few similar symptoms. New research suggests the conditions share genetic roots.

Postmortem brains point to impaired inhibition in autism

by  /  4 March 2010

Researchers have found a higher density of several types of interneurons — nerve cells that connect sensory and motor neurons in the brain— in postmortem brain tissue from individuals with autism, compared with healthy controls. The findings appear in the February issue of Acta Neurologica Scandinavica.

Loss of inhibitory neurons marks autism mouse models

by  /  24 November 2009

Autism may be the result of faulty wiring that occurs during early brain development, according to two independent studies that looked at the origins of circuit disruption.

MeCP2 loss leads to smaller neurons in brain region

by  /  18 November 2009

Deleting MeCP2, the gene that’s mutated in Rett syndrome, alters both the size and function of neurons in the mouse brain — at least in one brain region, the locus ceruleus — according to a 30 September report in the Journal of Neuroscience.

Autism study zooms in on five-gene strip on chromosome 16

by  /  10 November 2009

Genetic analysis of one Belgian family with a history of autism has pinpointed a piece of DNA on chromosome 16, within a segment thought to be missing in about one percent of all cases of autism. The unpublished data was presented on Saturday at the World Congress of Psychiatric Genetics in San Diego.

Study links autism to stem cell development

by  /  23 June 2009

The molecular defects that cause some cases of autism may arise during the development of neuronal stem cells, according to a new theory bolstered by several independent animal and human studies.
