Methods and related systems for modulating neural activity by cyclical blocking of conduction in peripheral neural structures with electrical blocking stimuli are disclosed. In an aspect, neural activity is blocked cyclically with an electrical blocking stimulus source implanted adjacent a nerve. In an aspect, a conduction block is produced in a sensory nerve. Neural modulation may be used, for example, to modulate an immune or inflammatory response or process.
