Synchrony ignite1/8/2023 Two magnetoencephalography experiments were conducted in which healthy human participants viewed masked words (Experiment I: active task, Dutch words Experiment II: passive task, Hebrew words) while high-frequency (broadband gamma) brain activity was measured. To address the unexplored neural mechanisms of piecemeal ignition of conscious perception, hierarchical script sensitivity of the putative visual word form area (VWFA) was exploited to signal null (i.e., sensory), partial (i.e., letter-level), and full (i.e., word-level) conscious perception. However, this neural evidence is not utterly congruent with rich behavioral data which rather point to piecemeal (i.e., graded) perceptual processing. The emergence of conscious visual perception is assumed to ignite late ( approximately 250 ms) gamma-band oscillations shortly after an initial ( approximately 100 ms) forward sweep of neural sensory (nonconscious) information.
