Rome, November 29 - A group of researchers in Canada have created an artificial brain able to recognize numbers, remember lists and write them with a robotic arm. The model, consisting of just 2.5 million neurons, was designed to resemble the different regions of the brain, according to an article in the Italian magazine 'Scienze'. Researchers at Waterloo University said that despite its capacity to compute information and perform functions, the model is still far from being able to reproduce the complexity of the human brain. The model performs simple operations that do not require any apparent effort to a human being, but that express perception and cognition. The team said that the artificial model can help researchers understand the brain's natural functions.
