Specifically, the study found that dogs have about 530 million cortical neurons compared to 250 million for cats. The way dogs' eyes are positioned in their heads also determines how well they can see.
The researchers tallied the numbers of nerve cells, or neurons, in eight species. (For what it's worth, humans have 16 billion).

This estimate has often been reported for many years in neuroscience and psychology textbooks and for many years was simply accepted as a relatively close approximation. Most times, people prefer to refer to an octopus with 8 limbs as having 6 arms and 2 legs.

Your hippocampus actually does create new brain cells during adulthood—about 1400 neurons per day.Scientists first noticed this in the 1960s, but the idea that the adult brain could make new neurons (called . Researchers have estimated that about 85,000 neurons die every day in the cerebral cortex. An important neurotransmitter in the neural economy of dogs is serotonin or 5-hydroxy-tryptamine (5-HT), which is especially important for the control of sleep cycles and has been implicated in the neurochemistry of stress, depression, and aggression. 500 million neurons, despite a twice larger .
