    Researchers have developed a method to fix and stain intact mouse brains for electron microscopy, according to a study published 21 October in Nature Methods. The technique allows them to trace the paths of neurons as they project across the brain.

    An autism-linked protein called CASPR2 promotes the development of dendrites, the bushy structures atop neurons that receive signals from other neurons, according to a study published 30 October in Proceedings of the National Academy of Sciences. Lowering CASPR2 levels leads to sparse dendrites and few synapses, the junctions between neurons.
