AWKWARD ZOMBIE

yeah well my freinds the one that made this forum and were quite the experts at zombies. our freinds are allways makin jokes sayin that when %^$& hits the fan there coming over to your house!

So why else would they crave human flesh?

No virus would survive if it made it's host unsustainable. The virus would definitely want to keep the digestion intact so it could continue absorbing nutrients.

My friends always say "Good lord, fix your grammar." And a bit of spelling. Also, you don't need to censor yourself.

Also it is, as always, hard to tell if people in this thread are joking or honestly believe flesh-eating/brain-munching zombies are a possibility.

Toxoplasmosa: the problem here, unlike viral or proteinacious pathogens, the average person this parasite is only a threat to the immunologically challenged mainly, and in rare cases infects a healthy person. If in rats it doesn't render them into "mindless" so much as fearless via (I'd suspect) blocking the limbic system's fear responses. This makes sense considering most of the limbic is located near both the 3 main ventricles and all major arteries in the brain where cysts can develop, which cause the behavoiral "blockages". Even people shown infected had neither their reasoning nor upper cerebral functions inhibited such as critical spatial and logic; fear inhibition excepted. Also, the other reasons it's not a viable candidate: 1)in the immunologically challenged, the end result is lethal encephalitis 2) it already exists in many species of common felines, so we've developed enough immunity unless you change fluffy's litter with skin lesions.
Psychotropics-alkaloids: Mass administration from aerosols for example, is simply not possible, to maintain efficacy instead of diffusing in the air. And continual administration every 24-48 hrs has to be considered along with incremental increases in dosage to deter potential immunity. Also, in water systems, typically, most alkaloids are chemically "basic" and react well with water, so again, the amounts
Rage viruses: "Super viruses" that would impair only one's higher cognitive functions and pain responses isn't possible. In cases of such sudden and drastic changes, the typical pathogen (such as ebola, hanta, or marburg viruses) are typically lethal, the main reason is that the unlucky recipient can't adapt via immunity or cellular compatability before "minor" symptoms like...say...hemorrhagic fever and systemic failure. To adopt aspects from another virus, it must first have similar coding (RNA or DNA based) or too many transcription errors occur. Considering that complete and adaptable transcription is essential for viral replication, if that doesn't happen, should a virion result, it'd be dead. Regarding CKD (Creutzfeldt-Jakob disease), it's caused from prions (proteinacious infectious particle) which are variant proteins that are inserted into the recipient's cells similarily to viral insertion. All prion diseases are collectively known as transmissible spongiform encephalopathies (TSEs), are untreatable and fatal with symptoms manifesting the most notable symptoms as it's in the worst stages.
Neurogenesis: What can be said here? Spontaneous tissue regen is currently NOT possible. That's it. Reason: at death, the circulatory system has stopped along with any waste management systems which means that the toxic and caustic chemicals that occur during decomp have no other means of disposal. And yet the machinery for either cellular maintenance or disposition have stopped so there's no way for the cells to either replicate, repair or be discarded. The 18 century experiments in neuromuscular stimulation via electrodes worked...for only a few hours to a couple days, but required an external source since any internal energy sources had long stopped (see above). As to "suspended animation" not only is the statement oxymoronic, and the article citing the experiment mentioned only 3hrs of suspension requiring a cocktail of saline and glucose and the animal subjects had to have the solution totally flushed out and replaced by their original blood (yeah, not simply any blood or can we say "rejection factor"?). Now to the headless chicken (beheaded & lived for 18 months), after thoroughly perusing this one, it's as figured, the almost all the brain and major viens/ arteries were still attached. As noted in the article, if one's brain stem is COMPLETELY severed, life stops IMMEDIATELY...NO EXCEPTIONS!
Nanobots: This was the more credible of the aforementioned ideas, however, it's unlikely that anyone would create nanbots either for rendering people as mindless automatons (zombies) or where the bots programming goes so horribly awry that they disconnect all neural functioning EXCEPT for the myelencephalon, metencephalon and mid brain. The reasons are simple, current theories in nano"bots" have one inherent programming flaw: they're soo small (the size of simple molecules), so the logic circuits capable of detailed instruction processing simply can't be installed. At best, they'd have simple "firmware" instructions for a single function, and require remote guidance to perform work. Also, if history and fiction teaches us anything, mindless subservience is a means to it's own ends. The current mass production industries such as automotive exemplify that well, you need obedient workers...THAT THINK! Even if only on minimalistic level. Therefore the operators were told to do such a thing as zombification of the entire population, the individuals involved have negated the very thing(s) you need to have a society that would support/ maintain the society in which you rely for your needs and wants. Besides, the best candidates for nanobot materials are highly susceptible to EMP's; again, no threat.

"this virus does not create life, it alters it."

This thread is like a giant rage-at-each-other party, except more civilized.

hospitals are always create new super viruses due to over medication and a sterile environment
