Software engineers as well as neuroscientists at University of Waterloo, Canada claimed that they have developed a closest model of the functioning human brain, known as Spaun which is advanced enough for passing the basic IQ tests. This is the virtual brain which functions on the supercomputer and comprises of a digital eye, which can be used for visual input. It also has the robotic arm which can be used for drawing the response.
The engineers as well as neuroscientists claimed that this was the most complex model of the world of human brain. Spaun or Semantic Pointer Architecture Unified Network comprises of 2.5 million simulated neurons which enables this brain to perform multiple tasks.
The tasks which this artificial brain can perform range from answering the questions to copy drawing as well as fluid reasoning. The tests were conducted in which the engineers and neuroscientists showed various letters as well as numbers, which were read in the memory by Spaun. Later, the other symbol or letter behaved like the command which tells Spaun what needs to be done with the memory.
