Abstract: Understanding brain function requires monitoring local and global brain dynamics. Two-photon imaging of the brain across mesoscopic scales has presented trade-offs between imaging area and acquisition speed. We describe a flexible cellular resolution two-photon microscope capable of simultaneous video rate acquisition of four independently targetable brain regions spanning an approximate five-millimeter field of view. With this system, we demonstrate the ability to measure calcium activity across mouse sensorimotor cortex at behaviorally relevant timescales.

The team utilized an ultrashort-pulsed 31.25 MHz, 2 W, 920nm fiber laser (Alcor, Spark Lasers) and a 7.8 W, 1040 nm fiber laser (Altair, Spark Lasers) as the illumination sources.

See all the great work being done by the research team at Chen Lab @ Boston University!
