[14] Treeshrews have a higher brain to body mass ratio than any other mammal, including humans. [15] Treeshrews hold about 10% of their body mass in ...
Although the human brain represents only 2% of the body weight, it receives 15% of the cardiac output, 20% of total body oxygen consumption, and 25% of total body glucose utilization. [138] The brain mostly uses glucose for energy, and deprivation of glucose, as can happen in hypoglycemia, can result in loss of consciousness. [139]
