I come from the side of neurobiology that deals directly with behavior
-- but it is invertebrate behavior where tracing complex patterns of
activity directly to the activity of identified neurons is the rule.
Perhaps Kandel, from the same school (except he was a slimy -- working
with molluscs instead of the more noble crunchies -- working with
arthropods) led him to make rather overbroad extensions to that
strange and minor group of animals with a hole running down the length
of their nervous systems.  Certainly he was very roundly criticized
from the outset, about fifty years ago, now, about how his dedication
to gill withdrawal in slugs had nothing at all to do with "real"
behavior that some overreaction would be expected.
