First complete map of every neuron in the brain revealed

Mapping every neuron in an adult fruit fly brain is a key step in understanding how brains function, including our own.

Fruit flies have about 140,000 neurons, which is a tiny number compared to the 86 billion in the human brain, making them much easier to study.

Mapping a whole fly brain, which measures less than a millimeter wide, into 7,000 thin slices was meticulously scanned using high-resolution electron microscopy.

The task of analyzing this enormous amount of data was made possible using machine learning, demonstrating the potential for AI technology to revolutionize neuroscience.

“The comprehensiveness of our wiring diagram has significant benefits for brain research and enables many kinds of studies that were not previously possible using wiring diagrams of portions of the fly brain,” noted the researchers. The study is published in the journal Nature . — Like what you read? Subscribe to our newsletter for engaging articles, exclusive content, and the latest updates. —.
