It’s an age-old argument between cat and dog lovers whether cats or dogs are the more intelligent! Things have now taken a new twist however, after scientists have for the first time, counted the number of cortical neurons in the brains of each species. The number of these cortical neurons are associated with thinking, planning and complex behaviour, all of which are considered as hallmarks of intelligent behaviour.
Researchers at Vanderbilt University in Nashville, USA have now discovered that dogs have around 530 million cortical neurons while cats have only 250 million. This turns on its head the long held theory amongst cat lovers that their favoured pet is the more intelligent. It now seems that dogs have the capability of doing more complex and flexible things with their lives than cats can. So next time you catch your canine friend staring into the distance – what is he or she really planning?!
