Avatar

A Psychoneurography is the process of drawing upon a person's self-image to form a sophiological avatar called a psychoneurograph. The machine used to enact the process is called a Psychoneurogram

Sophiological Avatars
Sophiological avatars are avatars composed of ideas made manifest, rather than immortalized flesh. Custom sophiological avatars are extremely expensive, however it is possible to use self-image as input to automatically generate a sophiological avatar.

Soulsearching
For all intents and purposes, self-image and the consciousness is the soul. Furthur, a psychoneurograph always gives the same results, regardless of a person's age or experience. As a result, a psychoneurograph is said to be the process of shedding a physical body to become a soul, a process nicknamed "soulsearching".
