1. A nerve stimulating apparatus comprising:
a plurality of stimulating units configured to respectively apply stimuli to a plurality of nerve regions branching from a particular nerve region of a living body, the stimuli being electrical stimuli, magnetic stimuli, acoustic stimuli, or mechanical stimuli; and
a stimulation timing controller configured to set generating timings of respectively generating the stimuli at the plurality of stimulating units,
wherein the stimulation timing controller sets the generating timings of generating the stimuli at the plurality of stimulating units based on response results of the particular nerve region, the response results being obtained in response to the stimuli that are respectively generated at the plurality of stimulating units and that are respectively applied to the plurality of nerve regions, and each of the response results being a magnetic field measured by a biomagnetic field measuring device,
wherein the stimulation timing controller respectively calculates a plurality of latencies each indicating a duration from when a respective one of the stimuli is applied to the living body to when a corresponding one of feature points appears in a response of the living body, for the plurality of stimulating units, based on current data estimated based on the measured magnetic field, and sets the generating timings based on the plurality of calculated latencies.
