by  /  16 December 2013

Taking antidepressants while pregnant doesn’t boost the risk of autism in the child, according to the largest study yet to search for a link, published 15 November in Clinical Epidemiology. However, the subgroup analyses that question the connection are based on numbers too small to draw a firm conclusion, experts say.

Brain’s immune cells boost rapid transmission of signals

by  /  11 November 2013

Two new studies bolster the emerging idea that microglia, cells that were long dismissed as passive soldiers of the brain’s immune system, are in fact actively involved in shoring up connections between neurons. The unpublished work was presented Sunday at the 2013 Society for Neuroscience annual meeting in San Diego.
