There is a video interview with the three Nobel Laureates at the link
shown below that I found of interest.

Interview with the 2000 Nobel Laureates in Physiology or Medicine,
Eric R. Kandel, Paul Greengard and Arvid Carlsson, by science writer
Peter Sylwan, 12 December 2000. The Laureates discuss whether we ever
will be able to understand the mechanisms of mind; talk about their
work and discoveries (6.24); making a paradigm shift in the way of
looking at the brain (12:19); going against a dominant field (16:11);
and their view of the future (19:00).
