claimIntegrated Information Theory (IIT) predicts that including prefrontal regions alongside posterior regions in decoding models will not significantly affect decoding accuracy.

measurementBayesian testing for iEEG yielded Bayes factor (BF)01 values of 5.11–8.65, supporting the null hypothesis of no face orientation decoding in prefrontal regions.

measurementBayesian testing across prefrontal regions of interest showed that 62–94% of voxels provided substantial evidence for the null hypothesis of no interareal connectivity, with Bayes factors (BF01) ranging from 3 to 7.75.

measurementDecoding of face orientation was robust from MEG cortical time series in posterior regions of interest (approximately 75% with pseudotrial aggregation), but was weaker (35%) in prefrontal regions of interest.

claimThe study tested the prediction from Integrated Information Theory (IIT) that prefrontal regions do not contribute further information beyond that specified by posterior areas, or may even degrade performance by introducing noise.

claimIn the study 'Adversarial testing of global neuronal workspace and integrated information theory', cross-task generalization of face–object decoding was significant in both posterior and prefrontal regions of interest (ROIs) within theory-predicted time windows.

measurementDecoding of face orientation (left, right, or front views) was achieved in posterior but not in prefrontal regions of interest using iEEG (approximately 95% with pseudotrial aggregation) and fMRI searchlight approach (approximately 45%).

measurementIn the Bayesian testing across prefrontal regions of interest, support for the alternative hypothesis of interareal connectivity was observed in only 0–4% of voxels.

claimAcross all modalities, orientation decoding was observed for letters and false fonts—but not objects—in posterior, but not prefrontal, regions of interest.

claimAcross modalities, face–object decoding occurred in both posterior and prefrontal regions of interest, which is consistent with predictions from both Integrated Information Theory (IIT) and Global Neuronal Workspace Theory (GNWT).

measurementObstructive sleep apnea syndrome (OSAS) affects 15–30% of older adults and causes chronic intermittent hypoxemia, which promotes neuroinflammation and damages hippocampal and prefrontal cortical regions.
