The brain of the elephant could be bigger than the human brain. From this
follows that its organization is primitive. A way to explain this is the
reduced capacity of the elephant brain to build concept models. If this is
true, he uses a huge capacity of the brain to build pure image models. The
term "elephant memory" can be associated with this feature. Thus, if it built
concept model, the elephant should be able to identify only limited landmarks
of the places it passes by. Using pure image models, it memorizes each tree
and each branch. This is a totally inefficient mode of brain functioning.
