Wiring diagram lays out connections between nearly 140,000 neurons and reveals new types of nerve cell.

"… Researchers are hoping to do that now that they have a new map — the most complete for any organism so far — of the brain of a single fruit fly (Drosophila melanogaster). The wiring diagram, or ‘connectome’, includes nearly 140,000 neurons and captures more than 54.5 million synapses, which are the connections between nerve cells.

… The map is described in a package of nine papers about the data published in Nature today. Its creators are part of a consortium known as FlyWire, co-led by neuroscientists Mala Murthy and Sebastian Seung at Princeton University in New Jersey."

See the associated Nature collection: The FlyWire connectome: neuronal wiring diagram of a complete fly brain, which also has links to the nine papers

All nine papers are open access!

    Well there is a phenomenon where your brain will make sound and sight “match up” even when it shouldn’t. Like if you hear and see a basketball bouncing 75 meters away, the sound should have about a 0.25 second delay. But your brain will make you perceive the sound as happening simultaneously with the ball hitting the ground, despite the fact that you could not perceive the visual and auditory sensations simultaneously. If you go further away with the ball, eventually there is a threshold where your start perceiving the delay. The auditory and visual sense would need to be somehow linked for this phenomenon to happen I’d say.

    I guess it’s the brains way of matching visual and auditory cues to try to make a better picture of the world. The brain is basically saying “that sound came from the ball” and you don’t even need to think consciously to know that.

      There’s also really tight coordination between sight and proprioception, as our visual processing seamlessly stitches together visual information into a three dimensional model of reality, even if we’re moving while taking in that visual information, through stereoscopic signals from two eyes.
