Abstract
A neural phantom device configured and arranged to produce a magnetic field to simulate a neural signal. The neural phantom device includes a driver having a signal source configured to produce a simulated neural signal, and either i) a carrier wave source configured to produce a carrier wave having a frequency of at least 250 Hz or ii) an optical carrier wave source configured to produce an optical carrier wave, wherein the driver is configured to modulate the simulated neural signal using the carrier wave or optical carrier wave to generate a modulated signal. The neural phantom device also includes a phantom configured to receive the modulated signal, demodulate the modulated signal to recover the simulated neural signal, and generate the magnetic field in response to the simulated neural signal.
