In the study of human intelligence, the major controversy is over what model applies best to the function of the human mind. Supporters of the computer metaphor have just received extra ammunition – a psychology professor has published research that appears to indicate that the prefrontal cortex and basal ganglia, the parts of the brain most critical to high-order intellectual abilities, do in fact operate in a manner analogous to that of a digital computer. This discovery will hopefully lead to a greater understanding of the way intelligence works, and will doubtless encourage singularitarians in their efforts to simulate the human mind electronically.
