Physiological effects produced in cats, dogs, rabbits, and rats by microwave irradiation (3-cm radar and 12.2-cm Microtherm) are duplicated in these animals by heating peripheral nerves with a warm-water or resistance-wire thermode. Identical effects occur when a temperature ranging between 45–47 C is attained by either of these means at a treated peripheral nerve or within tissue rich in peripheral nerve fibers. The response elicited by thermode or microwave stimulation includes arousal reactions, blood pressure and vascular responses, and signs of neurohumoral activity. We have demonstrated that the physiological effect of microwave radiation is a result of thermal stimulation of peripheral nerves which occurs independently of a significant increase in skin temperature or of total body heating.

In this paper, a parylene-based three-dimensional cuff electrode for peripheral nerve stimulation was proposed and simulated. The three-dimensional (3D) finite element model was built for simulation study of the electrode. The simulation results show this design has higher power efficiency than conventional planar electrode and it can realize selective stimulation of different fascicles in the target nerve. Moreover, the tripolar configuration has better control of the stimulation electric field than monopolar.

AbstractThe quality of tactile percepts evoked by skin vibrations depends on the frequency of stimulation: as frequency increases, the vibrotactile “pitch” increases. In the present study, we assessed the degree to which the quality of tactile percepts evoked via electrical stimulation of the somatosensory nerves is shaped by the frequency of the pulse train (PF). Participants with chronically-implanted peripheral nerve interfaces rated the quality of electrical pulse trains that varied in both PF and pulse width (PW) along a single continuum and also described the subjective quality of the sensory experience using perceptual descriptors. We found that increases in PF led to systematic increases in perceived frequency independent of PW, up to about 50 Hz, at which point perceived frequency leveled off or decreased. PF discrimination matched its vibrotactile counterpart, yielding a Weber fraction of ∼0.2 at low frequencies, but discrimination performance was abolished above 50 Hz. Finally, we found that PF systematically shaped quality as characterized by verbal descriptors at low but not high frequencies. Furthermore, even when probed in this complex, multi-dimensional space defined by descriptors, PF modulated tactile quality along a single perceptual continuum. In conclusion, we show that quality can be shaped by imposing temporal patterns on a fixed neural population, highlighting the importance of spike timing in the peripheral nerve. However, this temporal patterning can only be resolved up to about 50 Hz when stimulation is applied to populations of tactile nerve fibers.
