Research Bio

Na Ji is a professor in the Department of Physics and the Department of Neuroscience.  Using concepts in physics, her lab develops next-generation optical microscopy methods for understanding the brain at higher resolution, greater depth, and faster time scales. Besides inventing methods that make an immediate impact on neuroscience, they also aim to extend the applications of our technologies to other living (and nonliving) systems.

High-Speed Microscope Captures Fleeting Brain Signals

Electrical and chemical signals flash through our brains constantly as we move through the world, but it would take a high-speed camera and a window into the brain to capture their fleeting paths. University of California, Berkeley, investigators have now built such a camera: a microscope that can image the brain of an alert mouse 1,000 times a second, recording for the first time the passage of millisecond electrical pulses through neurons.
