7 August 2014 | 8:00 am

A Japanese research group led by Prof Norihiro Sadato, a professor of the National Institute for Physiological Sciences (NIPS), National Institutes of Natural Sciences (NINS), has found that people...

In children with autism, blood-oxytocin levels found to be in normal range

6 August 2014 | 8:00 am

Autism does not appear to be solely caused by a deficiency of oxytocin, but the hormone's universal ability to boost social function may prove useful in treating a subset of children with the...

Scientists unravel a neural circuit that could play an important role in autism

4 August 2014 | 8:00 am

Timing of neuronal generation is linked to how neurons achieve specific brain wiring

4 August 2014 | 7:00 am

Researchers at the University of California, San Diego School of Medicine have evidence suggesting that neurons in the developing brains of mice are guided by a simple but elegant birth order rule...

Biomedical discoveries accelerated by see-through organs and bodies

4 August 2014 | 7:00 am

The ability to see through organs and even the entire body to visualize long-range connections between cells as well as fine-grained cellular structures has been a long-time dream of biologists.
