Scientists know that in a substantial portion of babies who die of Sudden Infant Death Syndrome (SIDS), the brain cells that produce the neurotransmitter serotonin are too abundant. The cells are also misshapen. Scientific American discusses these findings in light of new research conducted in mice. Investigators using a mouse model to study anxiety found that 75% of mice bred to have excess serotonin receptors died young--during episodes marked by plunging heart rate and body temperature. Coincidence? Further research is on the way.
