Thanks to the contribution of my friend Agustin, an article that would act as a kind of virus T, this blog back to life. At least temporarily ... people contribute, send me anything, articles, images, things written by you or things you read on the subject and they were interesting. Well, enough of turns, here's the article:
Could it be some day a zombie apocalypse? If you are trying to get the answer of a scientist, this probably would be: no, not even by mistake. But Dr. Steven C. Schlozman, an assistant professor at Harvard Medical School has an answer that might surprise us all. 'I still think that zombies are fictional characters' Schlozman says in an interview,' but I'm not so sure. "
Dr. Schlozman recently published a medical article which explores how could a zombie brain. This is a reverse engineering analysis in which the scientist explains how a virus, bacteria, readiactivo material, etc. would affect our brain so we all start to show the characteristic symptoms of zombie state that the ataxic neurodegenerative syndrome called failure of satiety or ANSD by its acronym in English.
How would that affect the brain for a human to zombie state, according to Dr. Schlozman:
frontal lobe.
is part of the brain that allows us to think carefully and resolve problems in the abstract. The frontal lobe is responsible for controlling impulsivity, for example, if
you are in a fit of anger and is driving down the street or in a discussion, this part of the brain ensures that people do not run over or give him a
punched in the face of your opponent. According to Dr. Schlozman, the zombies are obviously not used much in the frontal lobe, they can not open doors or windows, can not go through complicated obstacles, in itself, can not solve problems and obviously their actions are governed by their impulses murderers. The frontal lobe of the zombie only takes orders from the thalamus, where sensory stimuli reach the brain.
The amygdala and anterior cingulate cortex.
As mentioned above, a zombie is governed by their impulses and basic emotions like anger and hunger, which live in the corners more primitive brain, including:
the amygdala. The brain of the crocodile, for example, is controlled primarily by the amygdala. Scientists have confirmed that inducing amygdala lesions
of certain animals and observing a decrease in their ability to react and attack. The balance is maintained by the anterior cingulate cortex, which 'modulates' the communication between the amygdala and the frontal lobe, ie, if that the amygdala generates fear, anger or lust, the cingulate cortex into action and allows the frontal lobe have time to think before acting.
Zombies to cingulate cortex have a defective because of damage to the frontal lobe, would have no way to modulate their feelings. Always hungry, always get angry.
The cerebellum and basal ganglia.
The zombies suffer from damage to the cerebellum and basal ganglia, parts of the brain that allow the body has fluid mobility and coordination. That's why zombies staggering walk, dragging their members and in some quake.
In the opinion of Dr. Schlozman, the 'infected' by the film Annihilation (28 days later in Spain) are not zombies because they have some kind of 'high activity in the area of \u200b\u200bthe cortex that allows them to hunt humans. " Additionally the 'infected' exhibit advanced motor skills and can even run, climb and jump on a super-human.
mirror neurons.
The mirror neuron theory tells us that these are neurons that are activated when an animal or person the same action you are observing run by another individual. Schlozman described the theory as a neurobiological model of empathy, which suggests that somehow or another are connected to each other.
zombies' brains are unable to 'connect', this disability is biological character. They do not seem angry, do not seem excited, do not seem scared. Only zombies appear and this is what scares no more about them.
The ventromedial hypothalamus.
According to Dr. Schlozman, zombies suffer from hyperphagia, a condition that causes the feeling of always being hungry. This is because the ventromedial hypothalamus, a nucleus of the hypothalamus is damaged. The result: The zombies eat and eat but never feel satiated.
How to stop a zombie?
Dr. Schlozman answers here with something that everyone already knew: Shoot or sever the head is the best solution.
