Abstract

The method and setup of EIT experimental study are introduced briefly first. Then the EIT data collected under auditory and visual stimuli respectively are analyzed, and the curves of reference data change with different current drive are shown. Meanwhile, auditory and visual EIT data versus reference data and the curve of EIT voltage changes due to two different stimuli of the same subject are given. A comparison is made between EIT voltage changes of human brain due to two different stimuli. A reconstructed image from these data is given. The effect of the number of the iteration and regularization parameter have on imaging quality are discussed in details. At last, a conclusion is drawn that data analysis and processing can help to investigate the activity of human brain.
