IBM’s Blue Gene Supercomputer Models a Cat’s Entire Brain
Using 144 terabytes of RAM, scientists simulate a cat’s cerebral cortex based on 1 billion neurons and 10 trillion synapses
Cats may retain an aura of mystery about their smug selves, but that could change with scientists using a supercomputer to simulate the the feline brain. That translates into 144 terabytes of working memory for the digital kitty mind.
IBM and Stanford University researchers modeled a cat’s cerebral cortex using the Blue Gene/IP supercomputer, which currently ranks as the fourth most powerful supercomputer in the world. They had simulated a full rat brain in 2007, and 1 percent of the human cerebral cortex this year.
The simulated cat brain still runs about 100 times slower than the real thing. But PhysOrg reports that a new algorithm called BlueMatter allows IBM researchers to diagram the connections among cortical and sub-cortical places within the human brain. The team then built the cat cortex simulation consisting of 1 billion brain cells and 10 trillion learning synapses, the communication connections among neurons. more>>>
