Consciousness is an emergent property of the brain, resulting from the communication of information across all its regions and cannot be reduced to something residing in specific areas that control for qualities like attention, hearing, or memory.
These are the results of a new experiment out of Vanderbilt University, published in the Proceedings of the National Academy of Sciences, in which researchers observed “whole-brain awareness” when individuals were asked to observe an image flashed briefly on a screen.
Researchers measured brain function using fMRI imaging technology and categorized participant responses into “high confidence” and “low confidence” categories, according to how sure each person was that they had seen the image.
Past experiments have demonstrated that different regions modulate different characteristics of consciousness such as attention, language, and self-control, but none of these qualities is sufficient on its own to create what we experience as consciousness.
