rare exceptions, even the most advanced computers do not have the ability to think on their own. They do what they are programmed to do, nothing more. Imagine a computer programmed to execute one function. This function cannot be paused, modified, or erased. No new data can be stored. No new commands can be installed. This computer will perform that one function, over and over, until its power source eventually shuts down. This is the zombie brain. An instinct-driven, unitask machine that is impervious to tampering and can only be destroyed.
B. Emotions
Feelings of any kind are not known to the walking dead. Every form of psychological warfare, from attempts at enraging the undead to provoking pity have all met with disaster. Joy, sadness, confidence, anxiety, love, hatred, fearâall of these feelings and thousands more that make up the human âheartâ are as useless to the living dead as the organ of the same name. Who knows if this is humanityâs greatest weakness or strength? The debate continues, and probably will forever.
C. Memories
A modern conceit is that a zombie retains the knowledge of its former life. We hear stories of the dead returning to their places of residence or work, operating familiar machinery, or even showing acts of mercy to loved ones. In truth, not a shred of proof exists to support this wishful thinking. Zombies could not possibly retain memories of their former lives in either the conscious or subconscious mind, because neither exist! A ghoul will not be distracted by the family pet, living relatives, familiar surroundings, etc. No matter who a person was in his former life, that person is gone, replaced by a mindless automaton with no instinct other than for feeding. This begs the question: Why do zombies prefer urban areas to the countryside? First, the undead do not prefer cities, but simply remain where they are reanimated. Second, the main reason zombies tend to stay in cities instead of fanning out into the countryside is because an urban zone holds the highest concentration of prey.
D. Physical Needs
Other than hunger (discussed later), the dead have shown none of the physical wants or needs expressed in mortal life. Zombies have never been observed to sleep or rest under any circumstances. They have not reacted to extreme heat or cold. In harsh weather, they have never sought shelter. Even something as simple as thirst is unknown to the living dead. Defying all laws of science, Solanum has created what could be described as a completely self-sufficient organism.
E. Communication
Zombies have no language skills. Although their vocal cords are capable of speech, their brain is not. The only vocal ability appears to be a deep-throated moan. This moan is released when zombies identify prey. The sound will remain low and steady until physical contact is made. It will then shift in tone and volume as the zombie commences its attack. This eerie sound, so typically associated with the walking dead, serves as a rallying cry for other zombies and, as has been recently discovered, is a potent psychological weapon.

F. Social Dynamics
Theories have always proliferated that the undead function as a collective force, from an army controlled by Satan to an insect-like pheromone-driven hive to the most recent notion that they achieve group consensus by telepathy. The truth is that zombies have no social organization to speak of. There is no hierarchy, no chain of command, no drive toward any type of collectivization. A horde of the undead, regardless of size, regardless of appearance, is simply a mass of individuals. If several hundred ghouls converge on a victimâs location, it is because each one is drawn by its own instinct. Zombies appear to be unaware of one another. Individuals have never been observed to react to the sight of one another at any range. This goes back to the question of sense: How does a zombie distinguish between one of
