Is it true that psychopaths lack the neurotransmitter oxytocin?
Heh, I actually read a thing about the opposite being true. Oxytocin isn't a neurotransmitter first of all, it's a mere mamillian hormone.
Second of all, the only personality profile not made more generous in their nature by this anti-oxidant was, guess what? The psychopath/sociopath.
No amount of theorapy seems to have the slightest effect on the sociopath; and some psychopharmalogical theorapies make it even worse, such as the use of anti-depressants.
Oxytocin therapy being ineffective for psychopathy does not mean there is no link between its deficiency and pschopathy nor that it makes the psychopath worse. The link between oxytocin deficiency and psychopathy and narcissism is based on studies done by Paul Zak (book Miracle Molecule; Psychology Today-Why Some People Are Evil, on-line). I don't know of any other studies on this. The link between psychopathy and abnormal extraversion (aka cholerics or undercontrollers) is very solidly based (on over 20 personality studies, eg., John, O., Srivastava, S. The Big 5 Trait Taxonomy: History, Measurement , and Theoretical Perspectives. In L. Pervin and O.P. John (Eds.), Handbook of Personality: Theory and Research (2nd ed.). New York: Guilford.).
Also, oxytocin is both a hormone and a neurotransmitter (see Oxytocin receptor genetic variation relates to empathy and stress reactivity in humans, by Sarina Rodrigues et al, pnas.org)

What shape is the hypothalamus?
Well, first of all, it's below the thalamus (I guess that's how it got it's name) and above the brain stem. It's very small. It resembles the shape of the size of an almond but the shape of a small pair of flip-flops stuck together or a mini-brain.
Two examples of hormone communication?
1. Sometimes you need a fast responce. Nerve cells carry electical impulses very quickly.But thei effect only lasts a very short time.
2. Sometime you need a responce that lasts for a longer time. For example, to control changes that take a long time, like growing. Hormones travel much more slowly. But their effects last much longer.

How fast are hormonal responses?
Slower than nervous responses.
Varies according to what hormone, for example the hormone epinephrine (adrenaline) works almost instantaneously to initiate increased mental alertness among other things. Some hormones take longer to take effect but most take action relatively quickly seconds -> hour
What happens to the male body during female hormone therapy?
When a transsexual woman starts taking hormones, a number of changes may occur. Muscle mass may decrease. Breast tissue will enlarge similarly to what girls experience during puberty. The skin may soften, and skin lesions may dry up or fall off. Beard growth might reduce slightly, and the fatty layer under the skin may thicken.
There may also be mental changes, though not all report these. Aggression may decrease. Certain types of abstract thought might diminish, possibly making it harder to work math problems or plot a driving route, though that can be overcome with effort. The sense of smell and hearing may intensify (though directionality of hearing may reduce), certain phobias might increase slightly, and anger may reduce. Some even report handwriting changes.

* Insulin - released by pancreas - encourages liver and muscle cells to absorb glucose from the blood; stimulates the conversion of glucose ----> glycogen in liver/muscle cells.
Explain how the nervous system and the endocrine system work together when adrenaline is released?
The sense of danger or anger are feelings registered by the nervous system which cause the release of adrenalin. Likewise, it is the adrenaline that prepares you to fight or to flee and helps you to focus your thoughts.
