Exactly when and where individual neurons develop is as important to our understanding of brain diseases as the underlying genetics, experts have shown.
Individual neurons can learn not only single responses to a particular signal, but also a series of reactions at precisely timed intervals. This is what emerges from a study at Lund University in Sweden.
If the mother is stressed over a longer period of time during pregnancy, the concentration of stress hormones in amniotic fluid rises, as proven by an interdisciplinary team of researchers from the University of Zurich. Short-term stress situations, however, do not seem to have an unfavorable effect on the development of the fetus.
