Gene on chromosome 22 leads to autism mouse model

Mice lacking a gene located in the chromosomal region 22q13 — which has been linked to autism — have motor learning and social deficits reminiscent of the disorder, according to unpublished findings presented in a poster session yesterday at the Society for Neuroscience meeting in Chicago.

Antibodies to fetal proteins trigger autism features

Antibodies directed against the fetal brain are present in some mothers of children with autism, confirming previous findings and suggesting that the antibodies could be used as a marker for the disorder, according to unpublished research presented yesterday at the Society for Neuroscience meeting in Chicago.

Neuroligin mutation triggers oxidative stress

Deleting a neuronal protein associated with autism causes oxidative stress — characterized by an excess of free radicals — which has been linked to diseases such as diabetes and Alzheimer’s, according to new research in worms. The results were presented yesterday at a poster session at the Society for Neuroscience meeting in Chicago.

Lack of corpus callosum linked to autistic features

People born without the large bundle of nerve fibers that bridges the brain's hemispheres have trouble identifying fearful faces, and don't look preferentially at others' eyes to perform this task, according to research presented Sunday at the Society for Neuroscience meeting in Chicago.

Neuroscientists need to do better at explaining basic mental health research

The knowledge gap between scientists, health-care professionals, policymakers and people with mental health conditions is growing, slowing the translation of basic science to new treatments. Like lawyers learning to present a case to the court, scientists should learn to educate nonscientists about their findings.

Dose, scan, repeat: Tracking the neurological effects of oral contraceptives

We know little about how the brain responds to oral contraceptives, despite their widespread use. I am committed to changing that: I scanned my brain 75 times over the course of a year and plan to make my data openly available.
