This peptide is the subject of a CNRS patent (granted in 2009) and has already successfully completed phases I and II of its regulatory clinical trials. An international phase III pivotal trial will begin in a few days’ time in the US when the first patient starts the treatment, before the trial is extended to Europe. Phase III is the last stage in the testing of a candidate drug, before it can be given market approval. The launch of phase III was the subject of a meeting involving around a hundred physicians on December 11-12, in Paris.

The amygdala, at the front end of the brain’s temporal lobe, has long been associated with negative behaviors generally, and specifically with fear. But new research shows this collection of nuclei can also influence positive social functions like kindness and what might be called charitable giving in humans. This could have implications for people with autism, schizophrenia or anxiety-related disorders, Platt said.

The findings are hugely important as 6-10% of pregnant women are currently being treated for depression with antidepressants. Prof. Bérard, an expert in the fields of pharmaceutical safety during pregnancy, came to her conclusions after reviewing data covering 145,456 pregnancies. “The variety of causes of autism remain unclear, but studies have shown that both genetics and environment can play a role,” she explained...

If you’re pondering whether to buy a Galaxy smartphone or iPhone this holiday season, the dorsomedial prefrontal cortex (PFC) might ultimately determine your choice. Results of a new study suggest that this region of the brain plays a critical role in making choices.

“A big question is how and where value information is represented in the brain, and what goes into that representation,” says Dr. Fellows. “Our research confirmed what savvy marketers already know: the longer you look at one of two objects, the more likely you’ll choose that object even if you initially valued the other one more...
