Christopher Ross WRA 110 Sec 742 Abstract 2 Polished Word Count: 200 Raichle, Marcus. “The Brain’s Dark Energy.” Scientific American. (2010): Web. 9 Oct. 2011 Neuroscientists have recently found that as the brain is at rest, it is actually encountering a wide expanse of intricate activity responsible for preparing itself for conscious activity. Neuroscientists previously thought of the background noise as irrelevant but recent research has found that this background noise is the interactions between a collaborating group of brain regions known as the brain's default mode network (DMN). Raichle explains, "The DMN may play a critical role in synchronizing all parts of the brain". Raichle supports his claim with the research of Hans Berger who used his

These ceaseless interactions are recorded through fluctuations within these blood oxygen level dependent or (BOLD) tests. The downtime is often referred to as the brain's "Dark Energy" and is also displayed in the slow cortical potentials ("SCP's ensure that the right computations occur in a coordinated fashion at exactly the correct moment."). The recent research of the DMN has shown that it is the master organizer of the brain and "Brain-imaging studies have found connections among brain cells in the DMN regions of patients with Alzheimer's, depression, autism, and even schizophrenia....
