Experts use new microscope, AI algorithm, and voltage indicators to image electrical activity deep in the brain

When studying the brain, researchers are just beginning to use a method known as voltage imaging to track neural activity in the living animal. While this approach is a promising way to better understand neuron firing, behavior, and cognition, there are limitations and risk factors. The practice requires putting a lot of light into the brain (which can lead to overheating) and only has the capacity to image ten neurons at a time.
