Spatiotemporal Analysis of Brain Activity during Tetrapod Image Recognition Process Using EEG

Abstract

In the previous study, some of the present authors had analyzed spatiotemporal human brain activities during the tetrapod image naming process, and pointed out that activation of the right angular gyrus depended on its shape. There are at least two processes in naming: the image recognition process and the name recalling process. It is not known whether the activity in right angular gyrus is involved in the recognition process. The present authors analyzed brain activities in image evoked recognition of four animals using equivalent current dipole source localization (ECDL) method.
