NLP 3 tries to make sense of certain behaviours by analysing the brain in its relationship with the mind. We need to make a sort of specification: our brain is made up of two hemispheres placed on the right and the left side of the cerebral organ. The left hemisphere is responsible for logic, the articulation of words, mathematics, and it is sequential; the right hemisphere, on the contrary, is responsible for imagination, dreams, creativity and irrationality; it is the place where our mental programs are stored.
