I agree Simon, pacinian corpuscles are very sensitive receptors for mechanical vibrations that can detect vibrations ~ hundreds of Hertz. I doubt that the stimuli from such a signal would be interpreted as a vibration. From the limited knowledge I have in sensory physiology I believe that these kind of experiments is carried out with signal bursts of 100-300 Hz at a prf of 1-50 Hz. Even though the receptors can detect the high frequency signals I think it is the low burst rate that is interpreted as a vibration.simonknight wrote: The skin obviously can't compete with the ears but I'm not sure I agree with the statement that it can't pick up vibrations in the range of hundreds of Hertz. There's plenty out there on skin sensitivity to vibration. The Meissner corpuscles function primarily as velocity detectors and are only senstive to about 40 hertz, but Pacinian corpuscles are sensitive bewteen 200Hz -350 Hz.
Very true and I have often been amazed by combined knowledge in fields far from ITM, by the contributers of this forum.simonknight wrote: ... amazing what you find out learning the pipes.
