Scientists have discovered the first evidence linking brain function variations between the left and right sides of the brain to size at birth and the weight of the placenta. The finding could shed new light on the causes of mental health problems in later life. . .

Disproportionate growth of the placenta and the fetus is thought to occur in pregnancies where the mother has been experiencing stress or where there have been problems with the availability of nutrients. Previous research has linked this pattern of growth to other diseases such as hypertension and greater physical responses to stress in later life. . .
