Fly Brain Breakthrough 'Huge Leap' To Unlock Human Mind

fjo3 shares a report from the BBC: They can walk, hover and the males can even sing love songs to woo mates -- all this with a brain that's tinier than a pinhead. Now for the first time scientists researching the brain of a fly have identified the position, shape and connections of every single one of its 130,000 cells and 50 million connections. It's the most detailed analysis of the brain of an adult animal ever produced. One leading brain specialist independent of the new research described the breakthrough as a "huge leap" in our understanding of our own brains. One of the research leaders said it would shed new light into aoethe mechanism of thought." [...] The images the scientists have produced, which have been published in the journal Nature, show a tangle of wiring that is as beautiful as it is complex.Its shape and structure holds the key to explaining how such a tiny organ can carry out so many powerful computational tasks. Developing a computer the size of a poppy seed capable of all these tasks is way beyond the ability of modern science. Dr Mala Murthy, another of the projecta(TM)s co-leaders, from Princeton University, said the new wiring diagram, known scientifically as a connectome, would be aoetransformative for neuroscientists." [...] The researchers have been able to identify separate circuits for many individual functions and show how they are connected. The wires involved with movement for example are at the base of the brain, whereas those for processing vision are towards the side. There are many more neurons involved in the latter because seeing requires much more computational power. While scientists already knew about the separate circuits they did not know how they were connected together. Anyone can view and download the fly connectome here.
