Map of Fruit Fly's Neuron Clusters Offers Glimpse Into Our Own Minds' Layout
The brain is a difficult place to wander around without a map. But while the human brain, with its billions of neurons, is far too vast a frontier for us to map using current means, researchers have been building a cell-by-cell detailed map of the neural pathways in the brains of fruit flys, shedding light on how the neurons in our own brains connect and function. The computer-based method of mind mapping relies upon the brains of flies that were modified to make certain neurons glow in the presence of laser light. Using a laser, an imaging system and computer mapping software, the team is laying image over image to create a detail of how different neuron populations behave and interact. The results thus far have already been surprising, and the map isn't even close to completion yet. From one fly's brain to the next, the neural pathways are more or less...
