Serotonin & Dopamine…technically the two things you enjoy

Serotonin earrings & pendant

Serotonin is a neurotransmitter whose function is transmitting impulses between nerve cells, regulating cyclic body processes and contributing to one’s overall sense of wellbeing and happiness.Serotonin is manufactured in the brain and the intestines, with 80-90% of it being found in the gastrointestinal tract. However,because Serotonin cannot cross the blood-brain barrier,the serotonin used as a neurotransmitter must be produced within the brain,where serotonin influences the majority of brain cells,both directly and indirectly.There is a direct link between depression and serotonin levels in the brain,subsequently antidepressant medications such as selective serotonin reuptake inhibitors (SSRIs) like St Johns Wort for example, affect the levels of serotonin in the body and are able to relieve the symptoms of depression,with continued use.

Normally once a neurotransmitter has fired its neural impulse it is generally reabsorbed at the synapse that produced it. SSRIs inhibit the re-absorption of serotonin (and norepinephrine) neurotransmitters and thus increase Serotonin levels in the nerve synapses in the brain, thus elevating mood.
