A new tool developed at HHMI's Janelia Research Campus lets scientists permanently mark neurons that are active at a particular time.
A new protein engineered by scientists at the Janelia Farm Research Campus fluoresces brightly each time it senses calcium, giving the scientists a way to visualize neuronal activity. The new protein is the most sensitive calcium sensor ever developed and the first to allow the detection of every neural impulse.
Designer ion channels that can turn neurons on or off will help researchers understand the connection between behavior and neural circuitry.
A new imaging tool lets researchers watch individual neurons in the brains of living animals light up as they work together to control the animal’s behavior.
