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.
New research suggests that training to do a new task causes groups of brain cells to “learn” how to work together more efficiently.
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.
Researchers have identified a chemical messenger that helps different sites on individual neurons coordinate with one another.
Even short bursts of activity in a few neurons can influence learning and decision making.
Genetically installing light-sensitive proteins in the brains of mice enables researchers to map functional brain wiring over long distances at unprecendeted levels of detail.
Neurons in the brains of mice sprout robust new connections when the animals adjust to new experiences.
