Creativity, as with other brain capabilities such as
intelligence, and memory, encompasses several
intertwined mental processes that have not been
completely deciphered by physiology.
The original thought is a mental process born
from the imagination. It is not known how
mental strategies differ between conventional
and creative thinking, but the quality of
creativity can be valued by the end result.
Creativity also develops in many animal species,
but it seems that the difference in competences
between two cerebral hemispheres is unique to
the human being. A great difficulty in
appreciating animal creativity is that most
species of brains differ completely from humans,
being specialized in responding to stimuli and
visual, olfactory, pressure and humidity needs.
We can only appreciate creativity more easily, in
behavioral differences between individuals in
social animals, songs, courtship, nest building,
and use of tools.
