Here, we provide evidence for the ignition process in humans by combining a magnetically-induced phosphene perception task with dense-electroencephalography. Functional cortical networks were identified and characterized using graph-theoretical analysis to quantify the impact of conscious perception on local (segregation) and distant (integration, key to ignition) processing. Conscious phosphene perception activated frequency-specific networks, each associated with a spatial scale of information processing: integration increased within an alpha-band functional network, versus a beta-band functional network for segregation. We speculate that such stimulus-induced modulation of the frequency-specific networks characterizing ignition could be exploited to assess non-invasively residual consciousness in minimally conscious patients.}, URL = {https://www.biorxiv.org/content/early/2018/10/22/449769}, eprint = {https://www.biorxiv.org/content/early/2018/10/22/449769.full.pdf}, journal = {bioRxiv} }
