The systematic turn in cognitive neuroscience

The modes of interaction within a system are important in understanding many artificial and natural entities. It sounds like a cliche to point out the importance of seeing the brain as a system. Even so, today we do not understand the essential systems level features that make it possible for the brain to realize its remarkable functionality, including dynamical adaptability, sensori-motor coordination, conceptualization, and context dependent learning. Here I discuss some essential systems level features of the brain based on neurophysiological evidences. Data from binocular rivalry experiments are presented as a specific instance. Finally, some basic constraints that a systems level brain model should satisfy are proposed.
