The authors have recorded electroencephalograms (EEGs) from subjects observing some images of human body parts and reading them silently. We estimated brain activities by use of the equivalent current dipole source localization (ECDL) method. The ECDs were localized to the right angular gyrus, the right fusiform gyrus and the right middle temporal gyrus, these areas are related to image recognition. However, the subject is left handed and her language recognition area is located on the right hemisphere. Hence these areas are also related to the language recognition.
