Abstract
In victims of sudden infant death syndrome [SIDS], phenylethanolamine-N-methyltransferase activity decreased in the nucleus retroambigus, the Kolliker-Fuse nucleus and the C2 area of medulla, whereas a decrease in the dopamine-.beta.-hydroxylase activity was found only in the C2 area. A hypoactivity of adrenergic neurons in respiratory and cardiac centers probably occurs in SIDS.
