An intracranial EEG dataset was collected from 38 epilepsy patients across three research centers as part of an adversarial collaboration testing Global Neuronal Workspace Theory and Integrated Information Theory. Participants viewed visual stimuli—faces, objects, letters, and false fonts—in three orientations and for three durations, performing a Go/No-Go target detection task. The dataset includes demographics, clinical information, electrode reconstructions, behavioral performance, and eye-tracking data, all converted to BIDS format. It is intended for reuse in consciousness science and vision neuroscience to investigate stimulus processing, target detection, and task-relevance.
A 75-year-old man with epilepsy experienced a progressive decline in cognition and behavior after a religious conversion 15 years earlier. He later developed severe religious delusions and Capgras syndrome. Brain imaging showed bilateral posterior cortical atrophy, chronic right parieto-occipital encephalomalacia, and right mesial temporal sclerosis. Electroencephalograms and neuropsychological testing indicated initial right temporal lobe abnormalities, followed by progressive frontal and bilateral dysfunction. The case suggests that a history of seizures, combined with sensory deprivation and progressive impairment of right posterior and bilateral anterior brain function, may have contributed to the religious conversion, which was followed by dementia and delusions with religious content.
