A decade ago, children with disabilities were almost always separated into their own rooms — or even buildings — with specialized teachers and lessons. But some research since then has shown that many of these children can learn well alongside healthy children, and vice versa.

The amygdala, a brain region that regulates fear and anxiety, shows abnormal neuronal signaling in a mouse model of fragile X syndrome, according to two studies published this summer. These are the first to explore cellular defects in the region in fragile X.

For a few hundred dollars and a bit of your spit, you can have parts of your DNA analyzed. If you’re more ambitious, $20,000 — and a lot less than that a year from now — will buy you the sequence of your entire genome. But the real question is should you, and others like you, find out what secrets your genome holds?

Changes in diagnostic practices, more active neighborhood networks, and an increase in the number of older parents may all contribute to the massive rates of autism in California, says a group of social scientists. But the numbers still don’t add up.

People with autism are asserting their right to be different. They say so-called ‘neurotypicals’ are the ones with communication problems, relying on the ‘animalistic means’ of body language, and they don’t understand why their focused, repetitive behaviors are thought to be problematic when neurotypicals indulge in obsessions such as sports and soap operas.

Three articles published in the past few weeks show that diagnostic categories marked off neatly on the page often bleed together messily in the clinic.

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.

The Autism Birth Cohort, based on data from 100,000 Norwegian children and their families, aims to uncover genetic and environmental factors contributing to the disorder.

You’ll never hear Jacqueline Crawley talk about an ‘autistic mouse’. In fact, in her keynote address at IMFAR in May, she implored the audience to never use those two words in the same sentence.

If you believe the hype about oxytocin, it’s nothing short of a wonder drug: it can make you trust a stranger, enhance a mother’s bond with her child and, according to a study published earlier this year, improve social skills in individuals with autism. But look more closely, and there is ample cause for caution.
