The normal adult human brain typically weighs between 1 and 1.5 kg (3 lb) and has an average volume of 1.6 litres. The mature human brain consumes some 20-25% of the energy used by the body, while the developing brain of an infant consumes around 60%. Such heavy energy usage generates large quantities of heat, which must be continually removed to prevent brain damage.
