A link
between oxytocin and serotonin in humans: Supporting evidence from
peripheral markers - Eur Neuropsychopharmacol. 2012 Jan 30 -
"Pharmacological studies indicate a functional
interaction between the serotonergic and oxytocinergic systems. In
particular, some selective serotonin (5-HT) reuptake inhibitors, such as
citalopram and fluvoxamine, seem to exert part of their antidepressant
effects through oxytocin (OT) release. Further, the administration of
fenfluramine, a serotonergic agonist, to healthy subjects increases plasma
OT levels. Interestingly, immunocytochemical and double-immunofluorescent
techniques revealed a high degree of overlap between 5-HT transporter (SERT)-labeled
fibers and OT-containing cells ... This result represents the first evidence
of an interaction between OT and SERT, as measured by [(3)H]-Par binding, at
peripheral levels in humans. Given the several activities mediated by both
OT and 5-HT, such a relationship might provide new perspectives and insights
into psychiatric disorders and/or social relationship disturbances, as well
as novel treatment strategies overcoming and/or integrating the serotonergic
paradigm" - See

A
gut-full of probiotics for your neurological well-being - Science Daily,
7/5/11 - "A recent study in mice, for example, showed that the presence of
neurochemicals such a serotonin in the bloodstream was due to direct uptake from
the gut ... Until recently the idea that probiotic bacteria administered to the
intestine could influence the brain seemed almost surreal ... Yet in
Lyte's paper the concept is supported by studies showing that microbes can
produce and respond to neurochemicals, which can induce neurological and
immunological effects on the host ... The research presents an idea for
selecting probiotic strains with neurological applications and linking this with
immune-modulatory effects, while highlighting the fact that microbial strains
already being widely ingested in fermented food can produce neurochemicals" -

Is
Exercise the Best Drug for Depression - Time Magazine, 6/19/10 -
"depressed adults who participated in an aerobic
exercise plan improved as much as those treated with sertraline, the drug
that was marketed as Zoloft ... Subsequent trials have repeated these
results, showing again and again that patients who undergo aerobic exercise
regimens see comparable improvement in their depression as those treated
with medication, and that both groups do better than patients given only a
placebo ... exercise may alter brain chemistry in much the same way that
antidepressant drugs do — regulating the key neurotransmitters serotonin and
norepinephrine"

- Sex, Sexuality, and Serotonin - Medscape, 7/20/04 -
"From our study of the brain, we have some nice evidence that elevated activity of dopamine is involved in that
intense sense of passion and arousal of romantic love. I also maintain in my book, Why We Love, that we're going to find out sometime that norepinephrine is also involved, largely because heightened activity of norepinephrine is also associated with focused attention, elevated energy, motivation to win a reward,
elation, and 2 characteristics of romantic love -- obsessional following and object imprinting ... low activity levels of serotonin are going to be involved"

levels of another brain chemical, serotonin. Low levels of serotonin are known to be a key factor in depression" - Note: St. Johns wort is believed to increase all three of the brain's primary chemicals, serotonin,
norepinephrine and dopamine.

Serotonin Could Mediate Heart Disease Link With Depression - Clinical Psychiatry News, 5/02
- Which Antidepression Drug Is Best? - WebMD, 4/30/02 -
"As initial therapy for depression, most doctors tend to use newer drugs
that target a specific brain chemical -- serotonin -- involved in depression. These drugs, called selective serotonin reuptake inhibitors or
SSRIs ... Effexor does this, too, but it isn't quite as specific. It also increases the
amount of another chemical -- norepinephrine -- in the brain ... Those who received Effexor were 43% more likely to have their depression go into remission than those taking SSRIs"

and gamma-amino butyric acid (GABA), as well as serotonin. Researchers in the Department of Pharmacology at the University of Frankfurt in Germany concluded, "no other antidepressant compound exhibits
a similar broad uptake-inhibiting profile.""
