Mesoscope Image of Neurons (IMAGE) University of California - Berkeley Caption Using a wide-field 'mesoscope,' UC Berkeley researchers were able to image neurons (green) in a large chunk of the cortex of the brain of a living mouse. The area shows neurites in a volume 4.2 mm × 4.2 mm × 100 microns. The dark branches are blood vessels.
