Largest brain mimicking supercomputer switched on

Why in News?

The world’s largest supercomputer designed to work in the same way as the human brain has been switched on for the first time.

Highlights:

*The world’s largest supercomputer designed to work in the same way as the human brain has been switched on for the first time.
*The newly formed million-processor-core Spiking Neural Network Architecture (SpiNNaker) machine is capable of completing more than 200 million actions per second.
*The SpiNNaker machine, designed and built in The University of Manchester in the UK.
*It can model more biological neurons in real time than any other machine on the planet.
*SpiNNaker is unique because, unlike traditional computers, it does not communicate by sending large amounts of information from point A to B via a standard network.
*SpiNNaker has been used to simulate high-level real-time processing in a range of isolated brain networks.
*This includes an 80,000 neuron model of a segment of the cortex, the outer layer of the brain that receives and processes information from the senses.
*It also has simulated a region of the brain called the Basal Ganglia – an area affected in Parkinson’s disease, meaning it has massive potential for neurological breakthroughs in science such as pharmaceutical testing.
*The power of SpiNNaker has even recently been harnessed to control a robot, the SpOmnibot.
*This robot uses the SpiNNaker system to interpret real-time visual information and navigate certain objects while ignoring others.
*Neuroscientists can now use SpiNNaker to help unlock some of the secrets of how the human brain works by running unprecedentedly large-scale simulations.
*It also works as a real-time neural simulator that allows roboticists to design large-scale neural networks into mobile robots so they can walk, talk and move with flexibility and low power.
*Biological neurons are basic brain cells present in the nervous system that communicate primarily by emitting ‘spikes’ of pure electro-chemical energy.
*Neuromorphic computing uses large-scale computer systems containing electronic circuits to mimic these spikes in a machine.
