It’s no secret that the entire humanity is split into two groups: cat people and dog people. And since this split happened a while ago, people have been arguing whether or not dogs are the smarter species or the other way around. A new study, which the journal Frontiers in Neuroanatomy recently published, might not completely solve this issue, but it might offer a new perspective when it comes to this quarrel. It seems that among carnivores, dogs stand out as having a very dense cerebral cortex. More neurons do not necessarily mean more intelligence, but it may count for some people.
In order to reach this result, a team of researchers analyzed the outer layers of the brains of various carnivorous animals. This also included cats and dogs. It may seem easy to understand that an animal needs a superior intelligence to be able to hunt prey. However, those extra brain cells have a cost. Apart from this, it seems that simply comparing the brains of different animal species is not that easy. Weighing their grey matter is not enough, because their relative body-and-brain sizes must also be taken into account.
Dogs have more neurons than cats
Moreover, performing the so-called encephalisation quotient, which is the brain size as a ration, might not offer enough proof of how intelligent than animal is. However, counting the brain cells might actually provide better results when it comes to processing power.
Past studies have said that cats have about 300 million neurons while dogs only have 160 million. The reality is that we should have waited more before handing this win to cats. The new study says that dogs have, in fact, about 530 million neuron, while cats only have 250 million. Even if dogs don’t have the largest brains of all the carnivores, they have the most neurons.
