Intrinsic optical signal (IOS) indicates activities of cerebral cortical neurons in the optical imaging method, which is one of the in vivo recording methods of activities of cerebral cortical neurons. We propose the IOS imaging method for craniotomy procedure. We designed a prototype CMOS image sensor device using 0.35-μm CMOS standard process for in vivo IOS imaging. The sensor device enables multi-functional recording of brain activities such as IOS, EEG, area image, electrical stimulation in order to improve reliability of diagnosis and allows simple measurement setup.
