The relationship of man to life, vapriyatieto to the world is set from birth, they found scientists from the University of Michigan. Will be optimistic or pessimistic, depends not so much by the environment in which we grow and nurture as biochemical and brain processes more accurately the concentration of neuropeptides in the brain, which in turn is determined by the inheritance of certain genes, they argue.
When the concentration is lower, the person is prone to depression and pessimism, and when is high, the mood is upbeat and the world shines in all colors of the rainbow. This relationship was established by scientists at the University of Michigan during the study with 180 volunteers.
In the study, they analyzed the reaction of people by tracking activity in the prefrontal cortex of words that cause different emotions as "murder", "success", "table", etc. The different activation was directly dependent on the amount of neuropeptides measured in laboratory tests.
