Topic: electrical impedance tomography

Introduction. There exists no method for non-invasive imaging of neural activity throughout the brain with a millisecond and millimetre resolution. EIT can theoretically achieve this by injecting a constant current with surface electrodes, measuring the voltage change associated with neural depolarization and reconstructing images of the activity. However, EIT with scalp electrodes was unsuccessful in vivo. MDEIT could improve image quality by measuring the magnetic field which is not attenuated by the skull. Aims. Image simulated neural activity in the human brain using MDEIT and EIT with sca
