Abstract

In this paper, preliminary experimental results are presented concerning the use of EIT for detecting changes within the human head. Non-invasive measurements were taken using a modified commercial EIT system to record voltage changes in 3 human subjects. In this experiment, auditory evoked response (AER) and visual evoked response (VER) were used as stimuli for brain activity. Analyses of illustrative raw data are presented for two different current drive electrode pairs, and preliminary samples of reconstructed images for simulated and real human data are shown.
