Lion being a carnivore animal has a big brain as compared to other animals. The basic parts of the lion brain is similar to humans. The embryonic or foetal brain of all the mammals develop on the same way. The embyronic spinal cord develops along common sequences and patterns. The nervous system elongates from a simple elongated tube of cells called neural cells. The head (Cranial) part of the embryonic tube expands and differentiates more robustly into several clusters of cells which emerges as Forebrain(telencephalon and diencephelon), midbrain(mesencephalon) and the hindbrain (metencephalon and myelencephalon).Usually, the brain size of male lion is bigger as compared with the female lion. The main components of the vertebrate brain are Medulla, Pons, Hypothalamus, Thalamus, Cerebellum, Olfactory lobe,hippocamus. The difference in brain of lion with other animals are as follows: a. The size of the brain: Lions usually has a big size of brain as compared to other animals but tiger. b. Social behaviour: The lions prefer to live with others due to the presence of neocortex which is absent in tigers which remains alone.
