Summary

Cognitive neuroscience continues to unravel complex perceptional and cognitive processes of the human brain, in part by combining functional and anatomical aspects into network models. For example, the “dual-route” computational model of reading aloud (lexical and nonlexical routes from print to speech) has provided insights into how the process works and where its pathological variants, such as dyslexia (1), may originate. As well, the standard model for how we recognize other people's faces (2) has emerged from behavioral studies and sparse neuropsychological evidence available in the 1980s, and by more recent functional magnetic imaging studies of brain activity (3) and genetic analysis (46). Still, we are only beginning to understand the brain's cognitive function. One limitation is that static functional models of cognition remain a rough approximation of the brain's dynamic processing power. Another challenge is that some cognitive dysfunctions may not be so obvious.
