MIT Microscope Captures Millisecond-Scale Voltage Activity Across Zebrafish Brains
MIT researchers adapted a light-sheet microscope to image electrical activity across the brains of larval zebrafish at up to 200 scans per second. The method captured individual voltage spikes and brain-wide responses to ultraviolet light, although usable signals appeared in about one-quarter of neurons and the system remains an experimental research tool.
