For full field light stimulation without the need of optics we developed a LED-based illumination system. In order to perform ERG experiments with explanted retinas the illumination system was integrated to a MEA setup. Using this assembly with different LEDs we took recordings from retinas.
The obtained I-O curves enabled the choice of a suitable LED for light stimulation. As it is easy to control, the illumination system could be simply adapted to a parallel recording setup.
