Figure S10. Light intensity of full-field stimulation by spectra 4 light source (470 nm illumination) as measured on the surface of the multi-electrode array chip.

We applied 8% intensity of the 470 nm light for full-field stimulation experiment (0.46 mW/mm²). For full-field stimulation under NBQX-APV treatment different intensities between 8% and 64% (2.74 mW/mm²) were applied.
