Zzibm has developed a mathematical model and simulation method that can simulate the operation of the cat brain.

A group fromIBM's crazy scientists recently claim that they have made "significant progress" in anthropomorphic computer chip technology"But their ultimate goal is to develop a computer system that Perfectly simulates the interaction between the human brain and the real world. Recently, this research groupThe Blue Gene supercomputer in the Lawrence litmus National Laboratory was used to successfully simulate cerebral cortex activity at the brain size level of the cat.Cerebral cortex is the main brain organ used by humans and animals for memory and thinking.

The project to simulate the cat's cerebral cortex activity was completed with the assistance of the National Laboratory of lithing moberkeley. The experiment simulated the working conditions of 1 billion neurons and 10 trillion nerve endings. In terms of speed, the simulated thinking process is about-times slower than the actual thinking process.
The size of the simulated cerebral cortex is only 4.5% of that of the human cerebral cortex, and the "thinking" speed is only 1/83 of the actual thinking speed on average. The supercomputer used to simulate a total of TB of memory, the computing speed can reach 0.5 pflop/s.
To simulate the activity of the human brain cortex, a memory system with a capacity of 4 PB may be required, to simulate the operation of the human brain in real time, a super computer with a computing capacity of 1 eflop/s (10 billion million floating point operations per second) needs to develop at the speed of its computing capability, it is expected that in the near future, people will be able to achieve the goal of simulating the human brain by computers.
The brain mathematical model used in this simulation was developed by IBM and Stanford University, during the establishment of the mathematical model, the Blue Gene of IBM was used to analyze the MRI image of the human brain, and the activity of the human brain cortex was measured and recorded.
IBM claims that the algorithms and simulation they developed opened the door for people to study how the human brain works and helped them develop cognitive chips with the ability to think ".
