Response to comment on "Wandering Minds: The Default Network and Stimulus-Independent Thought"
S. J. Gilbert, I. Dumontheil, J. S. Simons, C. D. Frith, P. W. Burgess suggest that activity in the default network may be due to the emergence of stimulus-oriented rather than stimulus-independent thought. Although both kinds of thought likely emerge during familiar tasks, we argue—and report data suggesting—that stimulus-independent thought dominates unconstrained cognitive periods.
