Abstract:
On the basis of investigating fundamental principle of EIT ( Electrical impedance tomo- graphy) technology, themethod and the setup of noninvasive experimental study of hum an brain due to external stimuli are discussed. According to the EIT data collected due to auditory and visual stimuli respectively, the curves of reference data changesunder different current drives, the auditory and visual EIT data versus reference data and the curve ofEIT voltage changes due to two different stimuli of the sam e subject are obtained. Through comparison and analysis, the rule of EIT voltage changes of human brain due to two different stimuli is revealed and the result helps to analyse the ac- tivity of brain and to reconstruct the EIT image.
