Yale researchers report on brain activity believed related to sudden infant death syndrome
...searchers at Harvard and Dartmouth who studied the brains of infants who died of SIDS found abnormalities of serotonin-containing neurons. "These are the same neurons that we have been studying in rats," he said.

When these plaques touch healthy brain cells, channels on the cell surface open up to let in a flood of calcium ions. This upsets the chemical balance of the cell, and it dies.
