Dogs Really May Be Smarter Than Cats, Study Suggests

Dogs Really May Be Smarter Than Cats, Study Suggests Dogs more brainier than cats

It's been accepted for publication in the journal Frontiers in Neuroanatomy.

According to Suzana Herculano-Houzel (self proclaimed dog-lover), neurons are the brain's information processing super computer.

If an animal has more of these neurons, it would follow that they would be able to engage in more of these activities, so the study-for the first time ever-counted the number of these neurons in the brains of several animals.

Dogs, it turns out, have about twice the number of neurons in their cerebral cortexes than what cats have, which suggests they could be about twice as intelligent. There appeared to be discrepancies when it came to neurons and cortex size, the study also found.

Utah State to play in Arizona Bowl versus New Mexico State
New Mexico State: The Aggies are playing in their first bowl game since the 1960 Sun Bowl, when they defeated Utah State. All-time, USU is 4-7 in its 11 bowl games and this marks the first repeat opponent for Utah State in a bowl game.

"I'm 100 percent a dog person", Ms. Herculano-Houzel said in the statement, "but, with that disclaimer, our findings mean to me that dogs have the biological capability of doing much more complex and flexible things with their lives than cats can". The more neurons the brain contains, the faster that processor is and the brain has the capacity for more complex behaviors, pattern recognition and the ability to make decisions based on past experiences or future perceptions.

The research found that dogs have about 530 million cortical neurons while cats have about 250 million. The analysis also discovered that raccoons pack the same number of cortical neurons as a dog into a brain the size of a cat's.

The researches believe the number of cortical neurons signifies the richness of an animal's mental state. After all, what good is all that brain power if dogs still drink out of the toilet? For example, the brain of a golden retriever has more neurons compared to the striped hyena, brown bear and African lion, even if the bear's cortex is three times bigger than the retriever's. But she said there's little evidence to say larger brain size universally leads to higher intelligence.

While the researchers may have added scientific clout to a household debate about cats and dogs, their work is part of a larger effort to use neurons as one quantifiable measure of intelligence. Score one for Team Cat!
