'This includes an ambitious project inside tech giant IBM, and today,
Big Blue released a research paper describing the latest fruits of
these labors. With this paper, published in the academic journal
Science, the company unveils what it calls TrueNorth, a custom-made
"brain-like" chip that builds on a simpler experimental system the
company released in 2011.
TrueNorth comes packed with 4,096 processor cores, and it mimics one
million human neurons and 256 million synapses, two of the fundamental
biological building blocks that make up the human brain. IBM calls
these "spiking neurons." What that means, essentially, is that the
chip can encode data as patterns of pulses, which is similar to one
of the many ways neuroscientists think the brain stores information.'
