Exploding head

From Wikipedia, the free encyclopedia

For the medical condition, see exploding head syndrome.

An exploding head is a surreal, involuntary gesture in fiction. It is sometimes evoked in cartoons and comics, from South Park to Dilbert. Its graphicality ranges from the comically distorted to a "blood, gore and eyes" look.

The phenomenon is triggered by extreme cognitive "overload" -- incoming stimuli by far outranges the capacity to process said stimuli, and anger and various other causes result in a violent discharge -- the exploding head.

The implication of this is that the unfortunate sufferer placed too much pressure on his brain, trying to figure out something unsolvable, unanswerable, undesirable, and most certainly unearthly.

The loss of one's head, especially by means of explosion, is universally-deemed as being a 'non-survivable injury', though some stories depict its swift reappearance or replacement (as with The Cheat). (See also Eternal Return). As such, exploding heads are typically restricted to minor and insignificant characters, in addition to those whose authors have very little regard for continuity (as with the creators of South Park, who have repeatedly killed Kenny McCormick).

While non-fictional head explosions are not possible without the aid of advanced weaponry or demolition tools, a persistent urban legend tells of a condition known as Hyper-Cerebral Electrosis which essentially has the same effect. Claims of the condition are known to have been made by the less-than-scrupulous Weekly World News in the 1990s.
