A neurologist's memories.

Oliver Sacks on his memories of a wartime bombing raid:

...But although I now know, intellectually, that this memory was "false," secondary, appropriated, translated, it still seems to me as real, as intensely my own, as before. Had it, I wondered, become as real, as personal, as strongly embedded in my psyche (and, presumably, my nervous system) as if it had been a genuine primary memory? Would psychoanalysis, or, for that matter, brain imaging, be able to tell the difference?...
