Watching The Brain Switch Off 'Self'
Everybody has experienced a sense of "losing oneself" in an activity--whether a movie, sport, sex, or meditation. Now, researchers have caught the brain in the act of losing "self" as it shuts down introspection during a demanding sensory task.
The researchers--led by Rafael Malach and Ilan Goldberg of the Weizmann Institute of Science reporting in the April 20, 2006, issue of Neuron--say their findings show that self-related function actually shuts down during such intense sensory tasks. Thus, an "observer" function in the brain does not appear to play an active part of in the production of our vivid sensory experiences. These findings go against common models of sensory experience that assume that there is some kind of "homunculus", or observer function in the brain that "looks at" sensory brain areas. Thus the finding, they said, has significance for understanding the basic nature of consciousness and perception.

Once the homunculus straw man is scattered, there is only the Silence, and then the RING.
Western civilization is as fucked up as it is because the post-Socratics bought into the egoistic delusion, and look where it's gotten us.
