Two peptides related to the fear of vasopressin and oxytocin, both scholars of the University of Lausanne have investigated their influence on the neurons of the amygdala, since in the cerebral amygdala is the ‘control’ of fear.
The physical effects of fear are due to the fluctuations of both peptides. Vasopressin is the cause of anxiety and anxiety that generates fear, and oxytocin acts against it. Well, they have seen that vasopressin acts on a certain area of the amygdala and oxytocin on an adjoining area. In addition, an oxytocin liberating neurotransmitter prevents vasopressin receptors from neurons.
According to the researchers, in these areas of the amygdala may be the key to anti-anxiety treatments.
