Artifact-free and high-temporal-resolution in vivo opto-electrophysiology with microLED optoelectrodes

The combination of in vivo extracellular recording and genetic-engineering-assisted optical stimulation is a powerful tool for the study of neuronal circuits. Precise analysis of complex neural circuits requires high-density integration of multiple cellular-size light sources and recording electrodes. However, high-density integration inevitably introduces stimulation artifact. We present minimal-stimulation-artifact (miniSTAR) μLED optoelectrodes that enable effective elimination of stimulation artifact. A multi-metal-layer structure with a shielding layer effectively suppresses capacitive coupling of stimulation signals. A heavily boron-doped silicon substrate silences the photovoltaic effect induced from LED illumination.

BrainSTEM (Brain STructured Experimental Metadata) is a collaborative electronic lab notebook for FAIR experimental neuroscience. It has a customizable web interface and a standardized yet flexible data model and is designed to capture a range of electrophysiology, imaging, and behavioral data. Granular permissions, including one-click public sharing, promote collaborations and open science. BrainSTEM is designed with ease of adoption and use as a primary consideration and facilitates compliance with NIH and other data-sharing requirements.

BrainSTEM can accelerate your science, promote collaboration, extend the lifetime of your data, and make FAIR data sharing easy. Please see the dedicated documentation website at below link.
