Green Xenon Posted July 22, 2009 Share Posted July 22, 2009 Hi: I have speculative neuroscience question. Let’s say that the PSTSNs in my body – and the ADFNs supplying them -- don’t have any refractory period or any other protections against hyper-excitability. PSTSN = Peripheral Somatic Tactile Sensory Nerve ADFN = A-Delta-Fiber-Nociceptor Non-ADFN = Sensory-receptor/nerve-ending that is not an ADFN or the portion of a nerve that is attached to such a sensory-receptor/nerve-ending ADFNPSTSN = A-Delta-Fiber-Nociceptor supplying a PSTSN PSTSNNon-ADFN = A non-ADFN supplying a PSTSN Tactile = Pertaining only to sense of touch [including temperature, pressure, pain, tickle, vibrations, movement, position, location etc.]. *Not* including any visual, auditory, gustatory, olfactory perceptions or any sensations associated with the sense of balance. Peripheral = pertaining only to the peripheral nervous system and not the central nervous system. Somatic = pertaining only to the somatic nervous system and not the visceral, autonomic, or enteric nervous systems Let’s say a mysterious entity decides to stimulate all the ADFNPSTSNs in my body to the maximum extent possible [in terms of extent to which an ADFNPSTSN is stimulated, how many ADFNPSTSNs per area are stimulated, and duration of stimulation] – without damaging any of my PSTSNs or their ADFNs, exceeding the maximum threshold of sensory feedback, or overloading the rest of my nervous system. During the ADFNPSTSN-excitement, the mystical entity also temporarily disconnects –without damaging – any PSTSNNon-ADFNs from my PSTSNs at the same time and at the same rate and amount at which it stimulates my ADFNPSTSNs. This disconnection is physically-harmless but causes my PSTSNNon-ADFNs to be completely unable to communicate with my PSTSNs until reconnection. In this hypothetical scenario, the ADFNPSTSN-excitement and simultaneous PSTSNNon-ADFN-disconnection do *not* occur suddenly or in a flash. They take place in a gradual, smooth, and sine-wave-like manner -- in terms of extent to which an ADFNPSTSN is stimulated, how many ADFNPSTSNs per area are stimulated, and how many PSTSNNon-ADFNs per area are disconnected from their PSTSNs. Hence there is no hint of a startle response at any level. What symptoms will I experience as a result of this extreme ADFNPSTSN excitement with simultaneous PSTSNNon-ADFN disconnection? My guess is that my sympathetic nervous system would be disrupted causing neurogenic shock. Do I guess right? Thanks, Green Xenon Link to comment Share on other sites More sharing options...
Leison Posted July 23, 2009 Share Posted July 23, 2009 didnt understand your PSTSNNon-ADFN part! did you mean to say PSTSN without pain sensation? Link to comment Share on other sites More sharing options...
Green Xenon Posted July 24, 2009 Author Share Posted July 24, 2009 didnt understand your PSTSNNon-ADFN part! did you mean to say PSTSN without pain sensation? Sorry for the confusion. A PSTSNNon-ADFN supplies a PSTSN and is any sensory-receptor/nerve-ending that is not an A-Delta-Fiber-Nociceptor. PSTSNNon-ADFN also refers to the portion of any nerve that is attached to a sensory-receptor/nerve-ending that is not an A-Delta-Fiber-Nociceptor if that portion of the nerve supplies a PSTSN.

Leison Posted July 24, 2009 Share Posted July 24, 2009 i think stimulation would cause you intense pain.for sympathetic to be disrupted, either brain or spinal cord should be stimulated instead of the periphiral part! what has PSTSNNon-ADFN to do here?

I asked my question after reading this: Quote from the above site: http://books.google.com/books?id=AB4fbXqlUJwC&pg=PA373&lpg=PA373&dq=%22extensive+superficial+burn%22+shock&source=bl&ots=wkO_EbLn9m&sig=ywnhw2l0NlXhfCE9DtVBPjbE8Ag&hl=en&ei=SBFVStunMpP6sQPMvJ3NDg&sa=X&oi=book_result&ct=result&resnum=6 "An extensive superficial burn produces great immediate shock, due to involvement of so many sensory nerve endings in the skin". After reading the above, I was wondering if the A-delta-fiber-nociception described in the initial post of this thread would cause a similar shock reaction.

Leison Posted August 1, 2009 Share Posted August 1, 2009 i think ur right then, intense pain causing shock. and during intense burn, even dehydration causes a person to go into shock. Link to comment Share on other sites More sharing options...
