Nonlinear two stage mechanotransduction model and neural response of Pacinian Corpuscle

This paper presents a biomechanical and neurophysiological model of skin and Pacinian Corpuscle (PC) to simulate its neural response over few 10s of Hz to 2000 Hz obtained from experiments. The PC neural responses are studied with sinusoidal stimuli to elucidate the relation between receptor potential and action potential and its variabilities. The overall model includes mechanical signal conditioning in both skin-layers and PC-lamellae, electro-mechanical transduction in the inner core of PC, followed by an improved Adaptive Relaxation Pulse Frequency Modulation (ARPFM). This model can be extended to simulate a group of PCs including many other variabilities in PC which will help in enhancing the technologies related to perception of vibration.
