Faulty connectivity found in mouse model of schizophrenia

by  /  18 June 2010

Mice engineered to carry a well-known risk factor for schizophrenia show disruptions in the connections between two brain regions that coordinate memory and learning. And these disruptions directly cause problems with working memory — the ability to actively hold information and to recall that information to make a decision, according to a study published in Nature.

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.

Variants in trust hormone receptor up the risk for autism

by  /  1 February 2010

Genetic variations that tweak the brain’s release of oxytocin — a hormone involved in social bonding and establishing trust — may increase the risk of developing autism or traits of the disorder, according to three new studies published in the past few months.

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.

Brain images uncover candidate genes for schizophrenia, autism

by  /  12 May 2009

Applying an emerging technique that combines genetic data and brain scans, researchers have identified two new genes involved in schizophrenia. The method, called ‘imaging genetics’, holds promise for linking genes to brain function in complex psychiatric disorders, including autism.

Research clarifies serotonin’s link to autism

by  /  13 March 2008

Serotonin is most commonly talked about in association with depression and anxiety. But for nearly 50 years, hyperserotonemia ― an elevated level of blood serotonin ― has been noted in roughly a third of autism cases.

Josh Huang: In dogged pursuit of autism’s off switch

by  /  3 January 2008

In 1982, Josh Huang was an impressionable young biology undergraduate at Shanghaiʼs FuDan University. Like some of his fellow Chinese students, he knew he wanted to be a neuroscientist, but with limited access to scientific journals, had no idea which big questions were then at the forefront of research.
