New method visualizes groups of neurons as they compute

Using a fluorescent probe that lights up when brain cells are electrically active, MIT and Boston University researchers have shown that they can image the activity of many neurons at once, in the brains of mice.

Just as rays of sunlight can be focused by a magnifying glass, beams of ultrasound can be focused—not to start a fire, but to converge on a specific target. The pulses of ultrasound are able to pass through obstructions ...
