Zombies are monsters that often appear in Western entertainment works, they are produced by human beings for some reason, they are inhumane corpses, strictly speaking, they are not living creatures. Zombies have been active from the black-and-white film era www.biquge.info to the present day, first appearing in "Night of the Living Dead", and have evolved into pop culture through the times. Zombies are fundamentally different from Chinese zombies. [1]

The word "zombie" comes from the Voodoo culture. According to Voodoo beliefs, a wizard can resurrect the dead, and after resurrection, they are also called zombies. Although the deceased can move and use tools, they are not autonomous and are manipulated by those who perform the resurrection ritual, so they are called as slaves.

In general works, zombies are basically turned into living people due to virus infection, but in fact, there are also cases where the dead are resurrected as zombies, such as the movie "Resident Evil 2", "Return of the Living Dead 1-2" and other plots. Thankfully, there is no record of the actual appearance of zombies in the real world, and zombies are often used in games, novels, comics, animations, TV series, and movies as a creative subject for inspiration.

Zombies[1], commonly known as the living dead. However, this is not necessarily the resurrection of the deceased, it may be the result of using strong drugs to stun the victim, and then using hallucination drugs and hypnosis to control the victim. For example, in Haiti, there are often many zombie legends, in fact, the sorcerer uses drugs to stun the victim, and then uses hallucination drugs and hypnosis to control the victim.

vision

After 2 hours, zombies will gradually lose their ability to see, but how they can distinguish between humans and their own kind is still debated. One theory is that human beings are more rapid and flexible than the undead, but this is not true for zombies who have completely autolyzed the retina and lost their ability to see, so humans try to confuse approaching zombies by imitating their movements, such as using staggering, clumsy and limping methods of travel without exception, and some experiments have been carried out on zombie sensory information collection methods. More evidence suggests that zombies may hunt through hearing and smell or other unknown sensory means. Some believe that zombies possess night vision, as this fact explains their behavior of hunting at night. This theory was eventually disproved because even zombies without eyes could effectively stalk their prey.

hearing

There is no doubt that zombies have excellent hearing. They don't just perceive sounds – they can also detect their location. The basic range of their hearing is comparable to that of humans. Experiments with ultra-high frequency and ultra-low frequency sound waves have denied the hypothesis that they can hear these sounds. Tests have also confirmed that zombies are attracted to any sound, not just those made by living creatures. Ghouls have been documented to be aware of sounds that are ignored by the living. In all likelihood, albeit unproven, this suggests that zombies use all of their senses equally. Humans are visually oriented from birth, and they only rely on other senses when their primary senses fail. And the living dead may not share this shortcoming with us. This, then, explains their ability to forage, hunt, and fight in complete darkness.

olfaction

Unlike hearing, the undead have a sharper sense of smell. Whether in combat or in the lab, they give the highest priority to distinguishing the taste of live prey in any environment. In some cases, especially in idealized wind conditions, zombies can even detect the smell of fresh corpses from a mile away. Again, this doesn't mean that ghouls have a better sense of smell than humans, it's just that they rely more on it. It is not possible to determine the details of the prey's special secretion signals: pheromones, bloody smell, etc. In the past, attempts were made to "mask" the unique smell of humans with perfumes, deodorants, or other strong-smelling substances in order to pass through the regions where the undead breed on a large scale. No one succeeded. Synthetic chemicals that represent the taste of living organisms are being used as experiments to lure or even drive away the living dead. And it will take at least a few years for a truly successful product to be completed. taste

Little is known about whether the taste buds of the living dead have changed. Zombies have the ability to distinguish between human and animal flesh, and they prefer the former. Ghouls also have a notable rejection of carrion in favor of freshly slaughtered prey. A human corpse that has been dead for more than 12 to 18 hours is denied food. The same is true for corpses that have been treated with preservatives or pickling. Although it is still uncertain how much this has to do with "taste". This judgment is more likely based on the sense of smell, or other instincts that have not yet been discovered. Why fresh human flesh is more popular.

touch

Zombies don't have literal physical perception. After being zombied, all the nerve receptors on the surface of the body are still dead. This is the best merit for them and the most terrible for the living. We, as human beings, have the ability to perceive physical pain to judge that we have been harmed. Our brain classifies these feelings, compares them to similar situations we have experienced, and archives them as warnings for future encounters. It's the gift that physiology and instinct give us to survive as a species. It is because of it that we see courage as a virtue and inspire people to take risks in ignoring this warning. It is precisely because of the lack of awareness and the ability to avoid pain that the living dead are so terrible. They don't care about wounds, so an attack can't be easily stopped. Even if a zombie's body is severely damaged, it will continue to attack until nothing is left.

sixth sense

Historical studies, along with laboratory and field observations, have shown that the living dead are able to search for prey even when all their sensory organs are damaged or even completely decayed. Does this mean that zombies have a sixth sense? Maybe. The real brain capacity of a living person is only 5% of all of them. It is possible for a virus to activate a certain perceptual pathway that was lost in evolution. This theory is most hotly debated in the war against the undead. To date, there is no scientific evidence to confirm either side's view.

medical

Regardless of ancient folklore or mythology, the undead have been physiologically proven to be incapable of self-healing. The damage to the cells will be maintained. Any wounds, regardless of size or environment, will remain in place until the zombie body reaches its limits. Various medical methods have been attempted on captured ghouls in an attempt to activate their self-healing.
