Research suggests a potential biological basis for SIDS, indicating that infants who die from the syndrome may have pre-existing differences in their brain structure and function compared to other infants.

Neurological Factors in Sudden Infant Death Syndrome (SIDS)

A research study compares the brain autopsies of infants who died from SIDS with infants who died from other known causes. The study reveals that the SIDS group had a significantly higher incidence of underdeveloped neurons in the brainstem area that controls breathing and waking from sleep. Based on this specific finding, what is the most logical conclusion?

A large-scale study compares brain autopsies of infants who died from unexplained respiratory arrest during sleep with those who died from other known causes. The study reveals that the first group of infants had significantly fewer receptors for a key neurotransmitter involved in arousal and breathing control. What is the most logical conclusion to draw from this specific finding?
