Scientists develop a mouse model of sudden infant death syndrome

Sudden Infant Death Syndrome (SIDS) is a condition that unexpectedly and unexplainably takes the lives of seemingly healthy babies aged between a month and a year. Now researchers of the European Molecular Biology Laboratory in Monterotondo, Italy, have developed a mouse model of the so-called crib or cot death, which remains the leading cause of death during the first year of life in developed countries. The model, published in this week's issue of Science, reveals that an imbalance of the neuronal signal serotonin in the brainstem is sufficient to cause sudden death in mice.
