I've been around a long time, and I've been interested in memory for a long time. And one of my earlier interests in molecular biology of memory led me to define the switch that converts short term to long term memory.

I was interested in the nature of human mental processes, which is what got me interested in psychoanalysis. And it became clear to me after a while that mental processes come from the brain, and in order to understand them, you need to be a biologist of the brain.

Events are moving so fast and what in one moment seems impossible, the next is happening. I'm sure historians will, in time, provide theories and analysis, but for now I think most of us simply want the tide stemmed.

I'd say Harvard graduates leave here with a sense of the possible and the limit - and a sense that there are no limits to what humans can do and that you can always be pushing, whatever limit you think might be there.
