      abstract     = {One problem of interpreting research on subconscious
                      processing is the possibility that participants are weakly
                      conscious of the stimuli. Here, we compared the fMRI BOLD
                      response in healthy adults to clearly visible single letters
                      (supraliminal presentation) with the response to letters
                      presented in the absence of any behavioural evidence of
                      visibility (subliminal presentation). No letter catch trials
                      served as a control condition. Forced-choice responses did
                      not differ from chance when letter-to-background contrast
                      was low, whereas they were almost $100\%$ correct when
                      contrast was high. A comparison of fMRI BOLD signals for
                      supraliminal and subliminal letters with the control trials
                      revealed a signal increase in left BA 37 (fusiform gyrus).
                      Comparison of supraliminal with subliminal letters showed a
                      significant increase in the right inferior frontal gyrus (BA
                      44, partly extending to BA 9 and BA 45, as well as BA 46).
                      Finally, a comparison of subliminal with supraliminal
                      letters showed increases in the left middle temporal gyrus
                      (BA 21) and the right extrastriate cortex (BA 19).},
