Cats vs. Dogs: Whos Smarter? Neuron Count Reveals the Answer!

Cats vs. Dogs: Who's Smarter? Neuron Count Reveals the Answer!

Cats and dogs are the most common pets in the world and an integral part of many people's lives. The question of which species is smarter has been a hot topic of debate for a long time. Some argue that cats are smarter because they seem more independent and self-reliant, and they can learn simple tricks more easily. Others argue that dogs are smarter because they are more readily trainable and more loyal to their owners.

So, who is smarter, cats or dogs? The answer may not be as simple as we think.

The Challenges of Measuring Animal Intelligence

Measuring animal intelligence has always been a challenge because we cannot rely on language and logic tests like we do with humans. Many scientists have tried to assess animal intelligence by observing their behavior, but this method is often subjective and limited.

For example, one experiment placed cats and dogs in a room with several cups, one of which contained food. The researchers pointed at the cup containing the food, and found that most dogs quickly understood the human gesture and accurately located the food. Most cats seemed uninterested in the researchers' gestures and preferred to play by themselves or just lay down, showing no obvious interest in the food.

This experiment seemed to suggest that dogs are smarter than cats because they are more receptive to human instructions. However, this experiment doesn't fully reflect the true intelligence levels of cats and dogs.

Firstly, the experimental method had some issues. Most domestic dogs are friendly to humans, have cheerful personalities, and enjoy interacting with people. Even if a dog hasn't been trained, it instinctively understands gestures and is willing to respond. This explains why most dogs actively respond to the researchers' gestures.

Cats, on the other hand, are inherently solitary and aloof creatures. They have less interaction with their owners compared to dogs, so they are less willing to respond to human gestures. This also explains why the experiment could be conducted successfully in a cat's own home.

Secondly, the experiment lacked quantitative analysis. While the final behavior of cats and dogs seemed similar, if a certain threshold was not met, the results would be very misleading.

How do we understand this? To put it simply, imagine a college student who has studied calculus and an elementary school student who only knows basic arithmetic. Both are given a simple addition problem within 100. In the end, both get the right answer. So we conclude that their mathematical abilities are equal! This is obviously wrong, a very serious error, so the previous "cup experiment" cannot detect which animal is smarter, or even if they are equally smart.

Neuron Count: Unlocking the Secrets of Intelligence

So, how can we assess the intelligence levels of cats and dogs more accurately? One method that scientists widely agree on is measuring the number of neurons in the cerebral cortex.

Neurons are the fundamental information processing units of the brain. The more neurons there are, the stronger the brain's ability to process information, and the higher the intelligence level. In simple terms, the stronger the cognitive ability, the smarter it is.

In the past, and even now, many people use relative brain volume and structural complexity as important criteria for assessing intelligence. In real life, there seems to be a lot of so-called evidence. For example, the larger the relative brain volume of carnivores, the stronger their ability to process external changes, the stronger their adaptability to the environment, and the stronger their processing ability.

But in reality, brain size is not a good indicator of intelligence because the number of neurons in brains of the same relative size can vary. To put it simply, imagine a room filled with boxes of the same size. If the gaps between the boxes are wide, only a few boxes are needed to fill the entire room. If the gaps are small, more boxes will be needed. In this analogy, the room can be understood as the brain.

While measuring neurons cannot be said to be completely accurate, it is the most scientifically effective method available at our current level of scientific understanding.

The Neuron Count Difference Between Cats and Dogs: Revealing the Truth About Intelligence

After measuring the number of neurons in the cerebral cortex of cats and dogs, scientists found that dogs have significantly more neurons than cats. Regardless of size, dogs have about 500 million neurons in their cerebral cortex, while cats have only 250 million, half that of dogs.

This finding suggests that dogs have a much greater capacity to process information than cats, which is consistent with what we observe in everyday life. For example, after simple training, dogs can recognize a wide range of everyday gestures and follow simple commands.

Neuron Count and Intelligence: A More Comprehensive Understanding

In addition to cats and dogs, scientists have also studied the number of neurons in the brains of other animals, finding a positive correlation between neuron count and intelligence level.

For example, elephants have a whopping 5.6 billion neurons in their cerebral cortex, indicating that they are the most intelligent animals in the animal kingdom after primates. This is consistent with our understanding of elephants.

Furthermore, people have analyzed a 180kg lion, which has 545 million neurons in its cerebral cortex, and a 350kg brown bear, which has 251 million neurons in its cerebral cortex. This suggests that dogs may have similar intelligence to animals like lions, while cats may have similar intelligence to animals like brown bears.

Measuring Neuron Count: Scientific Methods and Challenges

Some people may ask how humans know the number of neurons in the cerebral cortex of animals. While the process is complex, with the advancement of science, there are many institutions capable of conducting such experiments.

Simply put, the process involves separating the nuclei from the neurons in the cerebral cortex, then estimating the total number of nuclei by measuring the number of nuclei per unit volume, and finally estimating the number of neurons. While there may be some error in this process, if the error can be controlled within a small range, we can get more accurate results.

Conclusion: Intelligence Is Not a Single Standard

Through the study of neurons in the cerebral cortex, we find that although dogs exhibit a certain "stupid" attribute in everyday life, especially the notoriously clumsy Husky, most breeds of cats appear very calm and composed, giving the impression that cats are much smarter than dogs. However, in the face of quantitative data, the number of neurons in the cerebral cortex of dogs is far higher than that of cats, which means that the potential intelligence level of dogs may be higher.

Of course, intelligence is not a single standard, and it is also affected by other factors such as environment, experience, and training. We cannot judge the intelligence level of an animal based solely on neuron count.

Cats and dogs are two different species with their own unique intellectual strengths. Cats are better at independent thinking, while dogs are better at cooperating with humans. Understanding their differences allows us to better understand them and build good relationships with them.
