IBM Unveils a %u2018Brain-Like%u2019 Chip With 4,000 Processor Cores | Enterprise | WIRED. Will future doctors and scientists be able to transfer the contents of our brains to a computer chip? IBM has created a 4,000 core chip that effectively imitates a brain with one million neurons and 256 million synapses. It is just a first step, and we won't live to see the completion of the research; but, it will come. I would settle for one of these chips to enhance brain function. What are the possibilities to replace dying brain cells due to disease and old age? Brave new world.
