TABLE I. A partial list of the behavioral functions attributed to RF cells.

Cat stereotaxic coordinates were estimated from figures or taken from the authors’ description. General anatomical terms were used in rat and monkey studies and in cat studies where precise AP levels were not available. Third column lists percentage of encountered cells having function listed in column one.
