Fragile X protein linked to potassium channels

by  /  24 August 2010

Mouse models of fragile X syndrome show defects in two kinds of potassium channels — ubiquitous pores that control the flow of electrical current across neurons — in a brain area that processes sound, according to two papers published this summer.

Simple pathway

by  /  24 June 2010

A study of a rare form of epilepsy found in Amish groups adds heft to the idea that mTOR — a much-studied hub in a massive network of brain cell proteins — is an important biochemical player in autism.

Study implicates cell-adhesion proteins in autism

by  /  18 May 2010

Variations in two genes needed to form connections between brain cells may be associated with autism spectrum disorder, according to a study published 25 March in Molecular Autism. Some variants in the genes seem to increase susceptibility to autism, whereas others protect children from developing the disorder.

Imaging study refutes mirror neuron theory of autism

by  /  12 May 2010

Mirror neurons, which fire when someone either performs an action or observes it, are not defective in people with autism, scientists report today in Neuron. The findings dispute the theory that flaws in the mirror neuron system give rise to the disorder.

New autism gene points to cellular calcium imbalance

by  /  14 July 2009

A common variant of a gene called CACNA1G — which makes a channel that helps regulate calcium flow between cells — may increase the risk of developing autism, according to research published in Molecular Psychiatry.

Christopher Walsh: Solving mysteries of the mind in the Middle East

by  /  13 May 2008

At first glance, the waiting room at the Ministry of Health Hospital in Muscat, Oman, may look different than that of your average American hospital. Men dressed all in white and women in black burqas wait in separate rooms, even if they are members of the same family. But talking to these families soon reveals just how similar they are to their American counterparts, says Christopher Walsh, a neurologist who has studied neurodevelopmental disorders in the Middle East for nearly 10 years.
