title: Early signs of brain asymmetry.
abstract: A new study shows a leftward asymmetry of the choroid plexus in two-thirds of first-trimester human fetuses. This is the earliest brain asymmetry so far identified and may be a precursor to other asymmetries, including that of the temporal planum, which is evident from the 31st week of gestation.
