Outline of Final Research Achievements

Recently, optogenetics is getting popular for studying neuronal circuits. In this research, we developed a photostimulation device that used a fast XY scanner with potassium tantalate niobate (KTN) crystal. World-fast two photon excitation of fluorescein could be achieved with this newly developed photostimulation device with KTN scanner. Scan speed of the KTN scanner is more than 10 times faster than that of the galvano scanner. This research will advance brain science and natural science in which optical technique is more important.
