a. The bright area on this MRI to which the arrow
is pointing is 1) the frontal lobe 2)
cerebrospinal fliuid 3) a stroke b. Functions of
cortex not in this bright area are 1)
hearing 2) vision 3) touch c. I (you) think
this is most interesting because 1) relevance
to disability 2) localization of brain
functions 3) is like a painting
