Cerebral electricity (also known as "The Static") is a mysterious substance in the Interface universe that had existed alongside humanity for an unknown amount of time before revealing itself after the 1943 Philadelphia Experiment. The term was coined by the Greetings Robotics Corporation's CEO, Mr. Greetings. Cerebral electricity has been hypothesized to be sentient due to the language used by the CEO in Episode 03.
Cerebral electricity acts as a corporeal substance, as seen by its containment within vials and wells. It has been used to create artificial intelligence and can be harnessed by paranormal entities to manipulate their own physical form, or to interact with material objects. Cerebral electricity may also be a form of energy, as solid materials have been converted into cerebral electricity in the series.
It is theorized by fans that cerebral electricity is some kind of embodiment of an organisms soul or consciousness, which is released from its body after it dies. This can be seen in Episode 16 when the heron in the stream kills the frog, and in Episode 20 when Henryk's daughter can be seen releasing cerebral electricity from her face upon her death.
Very little is known about the origins of cerebral electricity. Mr. Greetings states that it is "not a foreign substance"; although so far there have been few clues as to where it came from, why or how it came to exist, or why it revealed itself after the Philadelphia Experiment.
In the narration of Episode 07, Mr. Greetings talks about how earth and the planets all formed from the same protoplanetary disk, and that the molecules that make up life came together and gradually "strove" to become more complex as time went on, suggesting that the formation of life was intentional to some degree. In Episode 21, cerebral electricity is visible on the surface of the sun following the Philadelphia Experiment, and when one considers the fact that the sun and planets formed from the same mass of gas and dust, this possibly means that all matter, at least in the solar system, is comprised of cerebral electricity at a base level. The fact that KAMI seems to be able to convert any matter into cerebral electricity and vice-versa is evidence to support this conclusion.
