Like humans, all mammals have a brain and central nervous system. These are made up of neurons or nerve cells which transmit information. Insects, amphibians, birds and reptiles also have brains though they are structurally different to mammalian brains. Mammal brains are around twice the size of birds of equivalent body mass and ten times that of a reptile. Learn more about animal behaviour here.
