Both are organo-phosphorous/phosphate compounds, and both act by inhibiting acetylcholinesterase, leading to sustained muscle contraction and usually death by asphyxiation.
Sarin however is much less stable due to the phosphorus-fluorine bond being easily broken by water or basic/nucleophilic materials. The products of this hydrolysis are relatively non-...
If you have a look at one of the most famous reference book in neuroscience "Principles of neural science" by Kandel (Fifth Edition), on page 22:
There is this figure:
And here is the description of the figure (extracts):
Most neurons in the vertebrate nervous system have several main
features in common. The cell body contains the nucleus, the ...
Axonal features means that there is evidence to suggest damage to the axon as opposed to the myelin sheath.
Essentially axonal damage leads to a reduction of amplitude with preservation of nerve conduction velocity whereas demyelination results in a reduction of conduction velocity.
The heart is not a center of intellect, it's a multi-chambered pump made primarily out of muscle.
There are however "heart signals", at least in a sense. The Sinoatrial Node is a specialized group of cells in the heart that produces regular action potentials across the cell membranes in the heart (causing the contractions that pump the blood) but this isn'...
The ingredients one by one
An alcohol sugar, and a sugar substitute. However, xylitol has become more widely used because a few type of bacteria (Streptococcus mutans) can process sorbitol and as such it is more anticariogenic.
In addition, sorbitol has one-third fewer calories and 60 % the sweetening activity of sucrose and is used as a sugar ...
TL:DR: No, not usually.
It this true or at least possible?
It is possible, but it is not common. People in an incredible amount of pain most often endure it without passing out. Others pass out at the sight of a drop of blood (a classmate of mine in medical school, every single time), the sight of a needle (a man in the ED who was about to get stitches), ...
EDIT: Its thoracic outlet syndrome. If I do certain stretches it goes away
So I looked into it, and I found those ingredients are actually good for "carpel tunnel" which has been found to be related to raynauds in some cases... this is essentially a pinched nerve due to bad posture (common in computer scientists). I don't think I have this in my hands,...
Your experience that alcohol warms your fingers and the fact that the drug nifedipine is used in Raynaud's symptoms relief suggest that the mechanism involved in warming fingers is vasodilation.
From the list of ingredients in your product, L-theanine can cause arterial vasodilation and could therefore be theoretically responsible for symptoms relief.
There are four different types of labyrinthitis (or vestibular neuritis):
usually caused by untreatedOtitis Media, middle ear infection
usually caused by a luetic pleurisy or meningitis.
usually caused by meningococcal diseases
usually caused by viral infections
The latter is ...
It is safest to be evaluated by a medical professional. The rules of HealthSE don't permit personal health advice questions. If you are still experiencing symptoms - as above, get seen urgently or phone for help.
In general, for various kinds of pain, you can re-train your brain to block some of the pain signals coming from your body in various ways: TENS, biofeedback, meditation, massage, guided imagery are some methods.1 Most use mental and physical distraction. Listening to music is an example of mental distraction; TENS is a physical distraction. Some you can ...
Endorphins are neuropeptides that can bind to opioid receptors, thus exerting an analgesic effect in the brain. You mention a counterpart, which is a badly defined concept in this context. There are other substances that can bind to these opioid receptors (opiods, for one :-)) and substances that can block opioid receptors without triggering them, like ...
