After several hours of 'work', the neuro-transmitters are depleted of what they need for good cognitive function. What they need is quality food which most of us don't eat enough of. Synapses are slower to exchange neurons. Basically, lack of active neurotransmitters is the reason for most people who are otherwise healthy. It's not the same mechanism as ...

Here's pretty much the first thing that popped up on pubmed:http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3144148/ So clearly there are direct neurotransmitter receptors on immune cells themselves. Pick a favorite neurotransmitters and search "xyz and the immune system". However, I can't tell you how relevant that is in terms of actually affecting large ...

Interesting notion. However, the main effects of the indoleamine-class of psychoactive compounds, including psilocybin and LSD (Shulgin, 1997), are generally ascribed to 5-HT2A receptors and the glutamatergic system (Aghajanian & Marek, 1999). The stimulant effects of the phenetylamines (PEAs) such as amphetamine and related compounds (Shulgin, 1991) ...

I think the question mainly highlight either of two misunderstandings: misunderstanding about the definition of heritability misunderstanding why the slope of the regression line is equal to heritability (in the narrow sense). Definition of heritability Please have a look at the post Why is a heritability coefficient not an index of “how genetic” ...

There has only been little research on the neurocognitive and neurophysiological effects of cannabis. There have been introductory neuroimaging studies in mainly non-psychotic populations, which show that cannabis does not affect gross brain anatomy. On the other hand however, it has been proved that cannabis does acutely increase cerebral blood flow (...

It's worth mentioning that, despite both neurones in your question being cholinergic, they aren't exactly the same: the pre-ganglionar neurones are nicotinic, while the parasympathetic post-ganglionar ones are muscarinic. And carbamates have more muscarinic activity than nicotinic activity. PS: this is not a good answer because it simply leads us to another ...

Well, I'm glad you're curious, but you must realise that your question is highly complex. You'd certainly have to refer to a research paper for the exact, factual information. All the same, I can tell you a bit about Dopamine (the pleasure hormone) based on recent reading. Dopamine creates pleasurable feelings when it is released in areas such as the ...
