The study suggests that consciousness is a state in which the brain is at optimal level of 'neural network connectedness.' The reason it is so difficult to study conscious experiences is that they are entirely internal and cannot be accessed by others. When we are conscious, brain regions communicate with a rich temperament, showing both positive and negative connections. These patterns are shown aboveAnother possibility is that they show evidence only of a very minimal awareness – referred to as a minimally conscious state. One represented very complex brain-wide dynamic interactions across a set of 42 brain regions that belong to six brain networks with important roles in cognition (see image above).
