Main Question or Discussion Point
How big is the contribution of endocrine glands to emotions? What if we only have brain and no endocrine glands.. what emotions remain?
Rather than answer that directly - not sure if there is a direct answer - I'll ask you some ponderings:How big is the contribution of endocrine glands to emotions? What if we only have brain and no endocrine glands.. what emotions remain?
Besides Adrenalin, testosterone, estrogen, stomach acidity, hypothalamo-pituitary axis secretions.. what else are there...Rather than answer that directly - not sure if there is a direct answer - I'll ask you some ponderings:
What secretions are from the endocrine glands?
What effect upon the body, organs, or cells do these secretions have?
What triggers the glands to produce secretions into the blood stream?
Are there long term affects as well as short term?
What other questions could you ask yourself, to solve the inquiry?
Just wondering the level of research you yourself have on the subject, say for example, high or low levels of testosterone.
I think a discussion could become quite involved beyond first level biology.
Good response.Besides Adrenalin, testosterone, estrogen, stomach acidity, hypothalamo-pituitary axis secretions.. what else are there...
most importantly.. do you know of latest research what really triggers them or maps (graphics illustrations, url, etc.) of some kind of the interactions between brain, endocrine glands, bloodstream secretions, nervous system and the mind?
It's ok if the discussion could be maximum multidisciplinary advanced. But for discussion sake (to avoid too broad topic).. perhaps we could just address "What triggers the glands to produce secretions into the blood stream?"....
If you will look at the table of contents of "Introduction to Behavioral Endocrinology".. the contents are just typical:Hmm. Endocrinology. So while this is both an interesting and a logical question, the answers are not simple, plus not all are not clearly understood.
Hormones come from many tissues, not just endocrine glands. Exposure of sunlight on skin produces a hormone precursor, which becomes a hormone that we Vitamin D. FWIW. And levels of Vitamin D can effect cognitive changes in some humans. Maybe this could fall into the 'emotion' pile of ideas.
This is the best answer I can give you:
Consider an idyllic quiet pond, that reflects blue sky and clouds, like a mirror. A kid standing next to you lobs a rock into the center of the pond. In a short while every part of the once glassy surface is roiled with waves. The rock is a point stimulus, okay? In terms of hormonal response, biochemical "waves" or perturbations may occur with a simple point stimulus. The pond analogy. A single hormone change can be like the rock in the pond effect.
Consider that your question does not always have a one to one answer for most things hormonal. Text books give a few examples like the fight-or-flight response. But other hormones are at play even there.
So let's not belabor a bunch of anecdotal incidents and claim they explain hormonal action. In general endocrine glands are derived from the same tissue as our nervous system. And our brain has an 'express route' to some of those glands. There are also molecules inside the brain that regulate emotions. Brain hormones if you like. You probably have heard of serotonin for example.
Best choice for inquiring minds:
Nelson and Kriegsfeld 'Introduction to Behavioral Endocrinology' which is exactly what you are asking for. Most college libraries will have a copy, the fourth edition is the current, best one. And AFAIK there is no useful comprehensive list of all hormones and their interactions.
Pop Science version: Sapolsky, "Why Zebras Don't Get Ulcers" I know if I were a zebra and had lions waiting around my drinking hole, I would certainly get ulcers....

In what sense? Endocrine glands are ways to regulate neural populations in a targeted way. They are, essentially, part of a control system. Emotions are something we experience that pertains to different states, presumably, in the electrical activity of neural populations - which is often reciprocally coupled to these control systems (i.e. the electrical activity of certain neural populations can influence endocrine glands which can alter the electrical properties of neurons.) There are many other chemical-based relationships between neurons and other systems.jtlz said:How big is the contribution of endocrine glands to emotions?
Endocrine system, in general, can be triggered by: neural activity, other hormonal systems, and the immune systems. As it pertains to emotions though, it's typically a response to external stimuli - thus, neural activity. However, different developmental periods in a life can correspond to different hormonal programs that will cause different feedback loops with neural activity (for example, sexual maturity and mating behavior)."What triggers the glands to produce secretions into the blood stream?"....
No, no no. I don't have stomach problem. I'm just researching the mechanism of emotional resonances that occurs in mobs behavior, mass protests, etc. Remember the Syrian tragedy was triggered by this. If human organism is independent.. even the mirror neutrons won't produce such intense emotion or feelings. There is another pathway that can produce it that links the emotions of humans. Have you heard of the quantum biology theories of Umezawa, Giuseppe Vitiello, and Freeman?No, I do not know of a specific connection like you mentioned. I think my answer may have confused you.

Especially note the ones that discuss IBS, stomach acid, or dyspepsia (fancy name for stomach pain) or ulcers. You do know about Helicobacter pylorii and ulcers, right? And colon problems or symptoms of pancreatitis are easily mistaken for a stomach problem.
It also sounds to me like you or someone close to you has a stomach disorder that is triggered by stress or other disease processes. If you have not seen a health professional the symptoms you mention could easily mask the true cause, something that needs medical attention, right now.
Why? An example: long term Helicobacter infection is a cause of stomach cancer as well as a primary cause of ulcers. Ulcers hurt and are worse under stress.
