The age-old debate about whether cats are smarter than dogs finally came to an end. An international group of researchers found that dogs have twice the number of neurons than cats have. Neurons improvise the information processing capability of a being. So scientifically, dogs are smarter than cats.
A total of six universities from USA, Brazil, Denmark and South Africa conducted the research work. The research was done in the lab of Suzana Herculano-Houzel who is an associate professor of psychology and biological sciences at Vanderbilt University.
‘’In 2005, my lab developed a very simple, fast and inexpensive method to count cells in brains and brain parts,’’ said Herculano-Houzel.
According to the information, the gathered after conducting research on many dogs and cats, a cat’s cerebral cortex has 250 million neurons, while a 15-pound dog has 429 million neurons.
A 64-pound golden retriever has 627 million neurons. That’s why retrievers are often regarded as the smartest of the dogs.
Having more neurons in cerebral cortex implies dogs have more cognitive capabilities than cats, says Suzana Herculano-Houzel.
