Paper Abstract

Optogenetics is a valuable tool set for the investigation of neuronal connections. Data on the connectome of human neurons is indispensable e.g. for the understanding of human neurodegenerative diseases. Providing this data for in vitro human stem-cell derived neuronal networks is the aim of our research. We use a holographic illumination setup with up to 1.7 kHz frame rate, 8 µm spatial resolution and 31 mm working distance for the stimulation of neurons expressing Channelrhodopsin2. In this work, we will present the measured functional connectivity of single neurons we retrieve using spatially resolved stimulation and simultaneous extracellular multi electrode recording.
