The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Breastfeeding boosts infants' IQs, but only if the babies have a specific genetic variant

This study looked at how long-chain polyunsaturated fatty acids (LC-PUFAS), which are present in human milk but not in cow's milk or most infant formulas, are metabolized. LC-PUFAS in breast milk, the authors said, is believed to enhance cognitive development because the fatty acids are required for efficient neurotransmission and are involved in neuronal growth and regeneration.
