Insulation for daydreams: a role for tonic norepinephrine in the facilitation of internally guided thought.

Although consciousness can be brought to bear on both perceptual and internally generated information, little is known about how these different cognitive modes are coordinated. Here we show that between-participant variance in thoughts unrelated to the task being performed (known as task unrelated...
