Maybe the "I-function", like long term memory, is not confined to a single, particular box or group of connected neurons but is spread-out in bits in pieces throughout the brain...in a sort of matrix of boxes in the over-arching architecture, after all, Professor Grobstein did describe a situation in which if one half of a person's brain was damaged (the example I belief was the experience with a stroke or brain aneurism in which the individual did not recall "having" the stroke but was nevertheless aware of something happening in her body even if it was non-specific per- say) and yet the quality of "I"..."I" saw, "I" felt, etc. was still present. Yet, in other cases where the other hemisphere of the brain was damaged in another person that same quality of the “I” persisted. Perhaps the "I" function is a redundant feature as well that exists in multiple areas of the brain whose influence, functionality, etc. can fluctuate depending on what specific processes is being monitored or occurring and in cases where emerging circumstances render one piece non-functional the redundancy or the plasticity of the system can compensate for damage that is done to another part.
