Enduring questions over which part of the brain helps produce that feeling of being 'awake' have been answered, thanks to stunningly detailed new brain imagery.
The images were then used to map a neural network of previously unseen pathways in the brain, called the 'default ascending arousal network' or dAAN, which they now theorize is the core region that helps humans sustain wakeful consciousness.
'Our goal was to map a human brain network that is critical to consciousness,' lead author Dr. Brian Edlow said, 'to provide clinicians with better tools to detect, predict, and promote recovery of consciousness in patients with severe brain injuries.'
