Functional split brain in a driving/listening paradigm
Open accessAbstract
Significance: When one drives on an easy route and listens to a radio, it is at times as if one’s brain splits into two separate entities: one that drives and one that listens. When, instead, one drives while listening to a global positioning system, there is only one functional stream. Here, using measures of information integration, we show that a brain may functionally split into two separate “driving” and “listening” systems when the listening task is unrelated to concurrent driving, but not when the two systems are related. This finding raises the possibility that under certain conditions of daily life, a single brain may support two independent functional streams, a “functional split brain” similar to what is observed in patients with an anatomical split.

IIT makes experimental predictions that have been validated in humans.
“IIT also makes several experimental predictions that have been validated in humans”
From Dissociating Artificial Intelligence from Artificial Consciousness (2024) · cites this paper as [30]
The Integrated Information section reports that the authors hypothesized higher integrated information during the integrated task and found that pattern in human participants. But the Discussion says the theory-related prediction about a transition to two streams of consciousness remains for future work. This study therefore supports a narrower experimental finding, not the claim that several IIT predictions have been validated in humans. (LLM, conf=0.86)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
