an abbreviation of analytical attenuation: a diminution (lessening) or weakening of the analyticalawareness of an individual for a brief or extensive period of time. If sufficiently great, it can result in unconsciousness. (It stems from the restimulation of an engram which contains pain and unconsciousness.) Used in this lecture with no particular meaning.
