Cortical expression of C1V1, a chimeric channelrhodopsin between channelrhodopsin-1 (ChR1) and one of the Volvox-derived channelrhodopsins. a–c Excitatory neurons in culture: C1V1-Venus immunoreactivity (a), CaMKII immunoreactivity (b) and the merge (c). d–f Inhibitory neurons in culture: C1V1-Venus immunoreactivity (d), GABA immunoreactivity (e) and the merge (f). g Co-expression of CaMKII and GABA in the Venus-positive neurons (summary of 10 visual fields). Scales, 50 µm for all. ***P < 0.0005, Mann–Whitney U test
