Introduction to the Default Mode Network

Default Mode Network Screencap

Hans Berger, inventor of the electroencephalogram was one of the first people to theorize that the brain remains perpetually active, even across a wide variety of mental states. Whether we are awake, sleeping, focused or daydreaming our brain is always hard at work. Obviously there are key differences between these states both physically and subjectively. But how do these differences translate into brain activity? Recent fMRI investigations have shown consistent patterns of activations in people’s brains when they are awake (but resting) and this has been deemed the “Default Mode” or “Resting State” network. This animation explores some relevant theories theories its activations and potential applications of the research. It was submitted to the Society for Neuroscience video contest in May 2011.
