Abstract :
Rapid localised heating (<100 ms) was achieved in rat hippocampal brain slices by millisecond exposures to radiofrequency (RF) fields, using a metal stimulating electrode to focus the energy into the tissue. This produced very high specific absorption rates (>5 MWmiddotkg-1) in the tissue near the tip of the electrode. Electrophysiological recordings of evoked responses were made to characterise the physiological effects of the heating pulses.
