A novel method for recording neuronal depolarization with recording at 125-825 Hz: implications for imaging fast neural activity in the brain with electrical impedance tomography.
Electrical Impedance Tomography has the unique potential to provide images of fast neural activity in the brain. We present a breakthrough which improved the SNR by two orders of magnitude and enabled the production of the first ever tomographic images of fast neural activity in rat brain during somatosensory and visual evoked potentials. The full imaging study based on this is shortly to be published; we expect it to create a storm of international interest as it will be the first method for tomographic imaging of fast neural activity with a resolution of msec and ~200 um in cerebral cortex.
