Many genes linked to autism disrupt the same developmental pathways during embryonic development and the first two weeks of life, according to a new study in mice. As the animals mature, those shared changes give way to more gene-specific phenotypes, suggesting that the underlying pathways shift over time.

The human brain forms trillions of synapses using only a few thousand cell-surface proteins to guide the process. How can distinct functional circuits form when there are far more neurons than molecules to guide them? New findings in mice provide an answer to this numerical puzzle: Across the brain, neurons repeatedly reuse the same pair of adhesion molecules to assemble distinct neural circuits, according to three studies published last month in Current Biology.

El secreto de su velocidad no está en sus genes: los animales proceden del mismo stock genético que un grupo de ratones de control.
