Study points to immune system's role in neural development

Between the ages of two and four, the human brain has an estimated one quadrillion synapses – the electrical connections between neurons. As we age, pruning out extraneous synapses enables existing ones to run more efficiently ...

Autism spectrum disorders

Signaling pathway may be key to why autism is more common in boys

Researchers aiming to understand why autism spectrum disorders (ASD) are more common in boys have discovered differences in a brain signaling pathway involved in reward learning and motivation that make male mice more vulnerable ...

Genetics

Study links gene mutation to neurodevelopmental disorders

A new model created by UCLA scientists reveals how the alteration of a specific gene increases the risk for neurodevelopmental problems in mice. When the researchers mutated the gene, it produced symptoms at specific ages ...
