After that initial change in the brain, however, the slow process of degradation began. For one thing, the power of recollection was different in different people, but always less powerful than memory storage, it appeared, and very hard to direct. So much was patterned into the brain but never retrieved. And then if one never remembered a pattern, never recollected and rehearsed it, then they never got the reinforcement of another run-through; and after about 150 years of storage, experiments suggested, the pattern began to degrade more and more rapidly, due apparently to the accumulated quantum effects of free radicals collecting randomly in the brain. This was apparently what was happening to the ancient ones; a breakdown process which began immediately after an event was patterned into the brain, eventually hit a cumulative level where the effects were catastrophic for the oscillatory patterns involved, and thus for the memories. It was probably about as clocklike, Sax thought glumly, as the thermodynamic clouding of the lens of the eye.

However— if one could rehearse all one’s memories, ecphorize them as some called it in the literature on the subject— from the Greek, meaning something like “echo transmission”— then it would reinforce the patterns, giving them a fresh start and setting the clock of degradation back to zero. A sort of longevity treatment for dimer patterns, in effect, sometimes referred to in the literature as anamnesis, or loss of forgetting. And after such treatment it would be easier to recall any given event, or at least as easy as it had been soon after the event happened. This was the general direction that work in memory reinforcement was taking. Some called the drugs and electrical devices involved in this process nootropics, a word which Sax read as “acting upon mind.” There were a lot of terms for the process being bandied about in the current literature, people scrambling through their Greek and Latin lexicons in the hope of becoming the namer of the phenomenon: Sax had seen mnemonics and mnemonistics, and mnemosynics, after the goddess of memory; also mimenskesthains, from the Greek verb “to remember.” Sax preferred memory reinforcer, although he also liked anamnesis, which seemed the most accurate term for what they were trying to do. He wanted to concoct an anamnestic.

But the practical difficulties of ecphorization— of remembering all one’s past, or even some particular part of it— were great. Not just finding the anamnestics that might stimulate such a process, but finding as well the time it would take! When one had lived two centuries, it seemed possible that it might take years to ecphorize all the significant events of one’s life.
