We are delighted that our collaborative paper with the Euler and Franke labs at the University of Tuebingen, Germany is now online on bioRxiv. Here, we describe our efforts to build a highly flexible yet low(ish) cost spatial stimulator capable of simultaneously delivering 6 arbitrary spectrum channels. We demonstrate the capability of the system during 2-photon imaging of visual neurons in the mouse and zebrafish.
