Abstract (in Japanese) (See Japanese page) 
(in English) In this study, we report the development of an implantable CMOS imaging device for GCaMP fluorescence imaging of mice brain under freely moving condition. We fabricated a new device by combination of two filters. One is a fluorescence filter for GCaMP detection and the other is a light-shielding filter that removes excitation light entering from the side and back of the image sensor. By introducing two filters, excitation light detection performance was improved, and leakage of excitation light was reduced. We also report in vivo GCaMP fluorescence imaging of mice brain with the new implantable device.
