Neurons deep in the fly’s brain tune in to some of the same basic visual features that neurons in bigger animals such as humans pick out in their surroundings. The new research is an important milestone toward understanding how the fly brain extracts relevant information about a visual scene to guide behavior.
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.
Janelia Farm researchers show it takes steady hands to measure the brain activity of a fruit fly while it is walking.
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.
HHMI has recruited 10 additional scientists to head research laboratories at its Janelia Farm Research Campus.
