In the countryside, the ancient role of the dog with an ineffable perception.
In the countryside, it has long been common for families to have dogs, on the one hand, to protect their homes, and on the other hand, for an unspeakable reason - dogs can perceive things that humans cannot see, and play a mysterious role in driving away evil spirits and protecting the house.
Dog, the legend of the exorcist.
Dogs are often depicted in literature and film as being able to see "them", and black dog blood and black donkey hooves are considered to be artifacts to ward off evil spirits. Although there are often exaggerated elements in literary and artistic works, village dog owners know that in the middle of the night, dogs will bark collectively into dark corners. Is it true that dogs can see "unclean things" that humans can't detect?
The world of darkness through the eyes of dogs.
Studies have found that the eye structure of dogs is different from that of humans. Dogs typically have larger eyes than humans with the same body proportions, which allows them to see more detail in dim environments. Whereas, the dog's retina is mainly made up of rod-shaped cells, making it more sensitive in dim environments. However, compared to humans, dogs have a weaker perception of color, presenting a distorted color TV picture.
The mystery of the canine membrane.
In addition to the structure of the eyeball, dogs also possess the canine membrane, a transparent membrane that is located under the cornea. This membrane collects and reflects light, making the dog's eyes glow when exposed to bright light. This allows dogs to see things at night that humans can't detect.
The unique nature of the auditory world.
The dog's auditory system is also one of its uniqueness. Dogs have larger, more flexible ears that are better able to receive information about the direction and distance of sounds. The difference in the structure of the inner ear allows dogs to hear a wider range of sound frequencies, which is twice as wide as that of humans. In addition, the dog's auditory cortex has a larger share of the brain, making it more sensitive and focused on sounds.
Sense of smell: Extrasensory abilities in dogs.
Dogs are known for their superior sense of smell. The dog's olfactory system has a unique structure, the nose has more olfactory receptors, and the olfactory sensitivity is about 1,200 times that of humans. The folds and depressions inside the nose increase the olfactory surface area, and the Jacobson organ helps the dog distinguish different odors. In addition, the way the dog breathes also helps to bring more odor molecules into the nasal passages, allowing the dog to perceive more odors.
The reason for the roar at night.
A dog's howl at night may be related to its perception beyond humans. The roar of the summer night may be an early warning of potential threats in the village, such as snakes, insects or wild animals. Since dogs are more sensitive to sight, hearing, and smell at night, they are able to detect potential danger in advance and bark as a protective measure.
Conclusion. Dogs are significantly superior to humans in terms of eyes, hearing, and smell, allowing them to perceive things that we can't perceive. However, it remains a mystery whether the "unclean things" can be seen. Nighttime roars may be more about driving away potential threats than seeing the supernatural. Extrasensory abilities in dogs are still a thought-provoking field that deserves to be explored and studied.
Comment: Extrasensory powers in dogs are thought-provoking.
This article on extrasensory in dogs, through the scientific analysis of dogs' eyes, hearing, smell, etc., reveals the scientific principles behind the mysterious behaviors that dogs exhibit at night. The author's presentation is clear and reasonable, providing the reader with a deep understanding of this interesting topic.
First, the article deciphers the structure of a dog's eyes and explains why dogs are able to see more detail at night. By comparing the differences in the visual systems of dogs and humans, we learned that dogs' large eyes and canine membranes make them more sensitive in dim environments, which explains why dogs bark at seemingly empty places in the middle of the night.
Secondly, the article delves into the dog's auditory system. Through the analysis of ear structure, the number of inner ear cells, the hearing range, and the speed of sound processing, we learned that dogs' auditory systems are more sensitive and able to perceive sounds that humans cannot perceive. This also provides a scientific basis for explaining that dogs are able to hear some sounds at night that humans can't.
Furthermore, the article details the dog's olfactory system, pointing out the dog's superior performance in the sense of smell. From the structure of the nose, the number of olfactory receptors, to the differences in the respiratory system, the dog's olfactory sensitivity is vividly revealed. This also allows dogs to smell scents that are imperceptible to humans, providing more interpretive possibilities for nighttime roaring.
However, in the article the author does not dismiss the claim that dogs can see "unclean things", but leaves this doubt with caution. This combination of science and mystery makes the article more engaging, and the reader feels respect for the unknown while thinking.
Overall, this article not only provides a deeper understanding of the perception of dogs, but also prompts us to think more broadly about the perception of other creatures in nature. The combination of scientific analysis and exploration of the unknown makes this article both convincing and mysterious, providing readers with a thought-provoking reading experience.
