Oxytocin often is called “hormone of love and fidelity”, but, as Jedi's
power, it is also has a dark side. Instead of creating social network links and
sense of well-being it can enhance the
emotional discomfort and anxiety.
The experiments were held on three types of mouse. The first group of
mouse there are no oxytocin receptors on
lateral septum of a brain, the second one has
very high level of receptors to oxytocin and the third one was normal. Mouse
in the first group placed in a cell with aggressive mouse six hours later did
not show any trace of fear, however, animals from the second group were very
frightened.
Thus, the experiment showed that oxytocin can
enhance all types of memory: both happy and unhappy. For example, if you were
humiliated by your classmates, oxytocin will enhance the pain.
