Scientists have a map of the wiring of a fruit fly's brain in a research project called FlyWire. The map of the neurons and connections the most detailed ever for a creature. This groundbreaking feat could revolutionize the field of neuroscience and secrets about our own brain. Brain specialist Dr Gregory Jefferis the BBC: "The mapping of the fly brain is really remarkable and will us get a real grasp of how our own brains ." He said it could insights into "the mechanism of thought". It took scientists years to the fly's pinhead-sized brain. They a detailed diagram of 139,255 neurons and 50 million connections.

The diagram of the fly's brain's neural pathways like a scientific work of art. It is a stunning, colourful web of neurons. The diagram is as a connectome. To it, the scientists the fruit fly brain into 7,000 microscopic slivers. Each of these was using an electron microscope that cells that were four-millionths of a millimetre wide. The researchers more than 8,400 different cell types. If the neural pathways were , they would stretch for 150 metres. The human brain has 86 billion neurons and trillions of connections. Current technology could not a connectome of our brain. That map still decades away.
