A Cat’s Brain is Similar To The Brain of a Human Being, The Explanation…


The brain of a domesticated cat is about 5 cm (2 in) long and weighs 25 – 30 g (0.88 – 1.06 oz). For a typical cat about 60cm (24in) long and a weight of 3.3 kg (7.3 lb), the brain would be at 0.91% of its total body mass, compared to 2.33% of total body mass in the human.

Despite the size differences, according to researchers at Tufts University School of Veterinary Medicine, the physical structure of cat and human brains are astonishingly similar. Both species have cerebral cortices with similar lobes specialized which perform different tasks.

The brains of cats and humans are both folded on the surface, allowing more brain to fit into a tinier area.

The cerebral cortex is the part of the brain responsible for learning, information processing, and also decision-making.

It is here that inputs from the senses and lower areas of the brain come meet to be interpreted and acted upon. The surface area of the cat’s cerebral cortex is 83 cm2, whereas the human cerebral cortex has a surface area of approximately 2500 cm2.

The cat has an estimated 300 million neurons within its cerebral cortex.
