Electro-Optical Monitoring of Human Cognitive Processes

This paper presents a new approach of the non-invasive biomedical monitoring of selected psychosomatic processes. The proposed method measures human skin conductivities (psycho-galvanic reflex - PGR) using the interdigitated array (IDA) of microelectrodes as well as skin temperature and skin reflectance using optical spectrometer, which will allow continual monitoring and analysis of complicated physiological and therapeutic processes. The psychological test was focused on short-time stress situation with a large scale of tasks.
