"Cognitive computer": a machine that can think

Psychiatrist Giulio Tononi from the University of Wisconsin (University of Wisconsin-Madison), who is involved in creating the “cognitive computer”, argues that the very idea of ​​creating a device that completely repeats the brain of a mammal is not as unreal as it may seem at first glance.

Giulio Tononi, scientists from Columbia University (Columbia University) and IBM specialists develop computer software, and nanotechnologists from Cornell University, Stanford University and the University of California at Merced ) must create a "hard disk".

As a result, experts plan to get a system comparable to the brain of a cat or a monkey. "Cognitive computer" will, by the way, be no more powerful than a 100-watt light bulb.

It is important to note that such experiments have become possible quite recently. In 2007, American experts have already tried to simulate the mouse brain. It took 55 million artificial neurons and half a trillion synapses (a specialized contact zone between the processes of nerve cells and other excitable and non-excitable cells, providing the transmission of the information signal).

The perfect "computer brain", according to Tononi, must be plastic, have the property of variability and receive knowledge from experience. The main difficulty is to teach a computer to analyze data (and not just perform a programmed set of functions), which is equivalent to the ability to think. This is the essence of "cognitive technology" - to recreate the structure, functions, principle of the brain in the technical apparatus.
