Zombie Invasion The Know-It-All Guide on the Dangers of the Living Dead WARNING The following images are graphic and not appropriate
for younger viewers! This image shows the start of the outbreak of the zombie virus in New York City. Local high schools
in New York
soon began to get
infected as the
epidemic spread
throughout the
state and into
neighboring states. The average citizen is most likely to contract the disease. If you spend time or have a lot of contact with people you are more prone to the Zombie Virus. Thalamus •This section of the brain is referred to as the "switchboard of the body" because it directs messages to the sensory receiving areas in the cortex and relays the replies to the cerebellum and medulla.
•The thalamus is the section of the brain that allows normal human beings to feel pain. Damages to the thalamus impair the sensory receptors in the infected so the zombies feel no pain. This characteristic makes them particularly dangerous, as it makes them difficult to impair. Amygdala •The Amygdala is made up of neural clusters and is linked to emotions and long-term memory.
•This part of the brain is responsible for fear behavior, such as rapid heartbeat. Zombies demonstrate no fear, thus their amygdala is damaged in some areas. However, other areas of their amygdala are hyperactive, as they are clearly very aggressive. They also have a very poor long-term memory, another sign that the disease targets this section of the brain. Temporal Lobes •Temporal lobes deal with some speech, language, and reading. They are located above each ear.
Information is received from the opposite ear in each of the auditory areas which aids in hearing.
•This section of the brain in the zombies is hypothesized to be damaged. Since zombies have slurred speech there is some agreement between neurologists that the temporal lobe is damaged. At this time it is hard to determine if the temporal lobe’s damage is affecting zombies auditorily.
The Wernicke's Area, a section in the temporal lobe that is needed in speech, has been severely damaged. As a result the zombies are suffering from slurred speech. The Zombie Brain Occipital Lobe •The occipital lobe is the part of the brain most associated with vision. The lobe works with the visual fields to receive messages.
•This lobe is one of the only parts of the brain that is not targeted by the disease as the zombie is able to see. This only increases their danger; they are able to focus on their victims. Reticular Formation The reticular formation controls arousal.
The zombie's constantly agitated state can be from some damage to the Reticular Formation. Anya V

Abby Caselli If you have seen these zombies - well, then you're probably a zombie too. Wanted Images Supplied By: remycarreiro.com, zombiesatemyface.com, dragonrosekohaku.deviantart.com Images Supplied By: halloweenforum.com, amymccracken.com, trendhunter.com At the moment, researchers are finding that most of the results are pointing to a toxic chemical that was cross contaminated in a Sweet Treat Cupcake factory in New York City. Although this is just a hypothesis from scientists, it is advised that people avoid eating cupcakes or other cake-like treats. Since the epidemic is so new, researchers are trying to find the cause of the virus. The Cause Presented By: Head Scientist Anya
Zombie Expert Abby Cerebellum The Cerebellum is called the “little brain” because it processes information from sensory inputs, both inputs and then organizes the output response. The cerebellum is also associated with conscious thought, movement, balance, and sensation.
Motor functions of zombies are impaired. These zombies lack the ability to walk well; they have a hard time balancing. Having impaired movement, such as the symptomatic "zombie walk", is associated with impairments in the cerebellum. Overall, balance and walking (motor skill) are not human-like in zombies because of the damages in this part of the brain. Homo-Coprophagus-
Somnambulusitis, more
commonly known as the
"Zombie Virus", is a virus
similar to meningitis. Often
contracted orally, it makes its
way to the brain to cause
inflammation, clots, and
herniation. The intracranial pressure and lack of
blood flow cause certain parts of the
brain to malfunction or become
impaired. Emotions, coordination, speech,
and memory are all affected. The
symptoms of Zombie Virus present
themselves about a week after the
person is infected. Until then, they are
highly contagious and the disease can
easily spread to anyone they come in
contact with. The following information
will explain which parts of the brain are most targeted
by this virus. Warning -
the damage and resulting
symptoms may be
shocking. Parietal Lobe The Parietal Lobes receive sensory input for touch and body position. Overall, it affects tactile sensation, response to internal stimuli, sensory comprehension, some language, reading, and a little bit of visual processing (depending on the function - mostly spatial or for action purposes).
Part of the Parietal Lobe is damaged. Since it affects tactile sensation, there is some evidence that the zombies are unable to feel pain because the Parietal Lobe is impaired. However, scientists are not sure to what extent this part of the brain is damaged. Language of a zombie is affected; therefore, it is possible that a great deal of the Parietal Lobe is damaged. However, scientists cannot test the reading ability of the zombies. Also, evidence is lacking to show the visual functions of a zombie. Therefore, it can be assumed that a few parts of this lobe is affected by the virus, but scientists cannot be sure if all of its functions are impaired. Frontal Lobe Muscle movement, speaking, judgment, and making plans are all functions the frontal lobe is in charge of. Overall, it controls attention, behavior, abstract thinking, problem solving, creative thought, emotion, intellect, judgment, coordinated movements, muscle moments, sense of smell, physical reactions, and personality.
The frontal lobe is damaged in all zombies, as their movement and judgment is abnormal. This is specifically seen in the case of coordinated movement. The zombies use their hands to help keep their balance, indicating that they lack the ability and skill of walking properly. Zombies are also incapable of problem solving, a clear sign that the virus is targeting the frontal lobe. Lastly, scientists have found that zombies lack emotions and human-like thoughts, again indicating that this area of the brain is damaged and cannot control these traits the same way it could in an uninfected human being. The Zombie brain is not just about eating humans. Let's take a closer look. Hypothalamus •This section of the brain directs several daily activities such as eating and drinking. It also controls body temperature and some emotion and links the nervous system to the endocrine system via the pituitary gland. This part of the brain also controls circadian rhythm.
•Damage to the hypothalamus results in excessive hunger, a key trait of zombies. Since the hypothalamus also has some effect on emotion, it is likely that this section of the brain is malfunctioning, as zombies lack human-like emotions, particularly fear and empathy. This disease also targets the circadian rhythm of the zombies; therefore, they need no sleep. Hippocampus The hippocampus is part of the brain's limbic system, and is primarily responsible for controlling memory and memory consolidation. Scientists have concluded that the Zombie Virus has a definite effect on this part of the brain, as zombies are incapable forming and recalling long-term memories, yet have no difficulty with short-term memories. Scientists are still trying to figure out how the virus impacts the hippocampus and interferes with memory consolidation, but for now, they are hypothesizing that it causes a form of anterograde amnesia. This form of amnesia makes it difficult for the individual who has it to commit to memory, but enables them to know it for a short period of time.
