Abstract :
Delivering electric pulses to brain tissues has been done by Transcranial Magnetic Stimulation, but the resolution and penetration depth are limited. We use picosecond electric pulses to stimulate neurons (activation or inhibition). The delivery of such short pulses was simulated by CST Microwave Studio. Pulses were delivered to a shallow, subcranial target using a conical dielectric antenna. Results of the simulation show the antenna is capable of creating an electric field distribution less than the size of the antenna aperture.
