But I do not believe that elephants, or in fact any other creature as
far as my Googling has found, has 6 full layers of cortical tissue, and
it is this, rather than total area or volume of tissue which allows us
to think on a more abstract level than that of other creatures and gives
us our "creative" edge. As I understand it, area relates proportionally
to bandwidth while each layer allows the generalizations created from
the detailed input of the lower layer to be generalized and abstracted
to a greater degree. Please correct me if I am mistaken here, as my
primary source of input about this topic has been Mr. Hawkins' book. If
there are seminal papers or texts that I should read in order to ask
better questions I would love to know about them.
