- Recent anatomical and physiological mapping experiments in the cortex
of non-human primates and other mammals have suggested modification
of a very old view of brain function that we described in class as
the "Cell Doctrine". The modern version of that idea is that
sense organs project to modality-specific cortical areas, but that
these modality-specific areas then eventually all project to a central
polymodal or amodal "association cortex" that is the true site of higher
First, describe the traditional view of a central amodal cortex for higher
level functions and then summarize data that has suggested changes
in the traditional view. Second, how might these newer data be relevant
to understanding the human brain, and particularly the peculiar linguistic
abilities of humans?
Be sure to mention at least one piece of evidence from each of
all three of the following kinds of studies: neurobiological
(visual, somatosensory, auditory, motor areas in animals and humans),
neuropsychological (studies of function after brain damage) and the
behavioral/linguistic (psychology experiments on humans).
