I don’t get this. Why would anyone pay $2K to get a preprint commented by 2-3 experts, if it doesn’t result in a “peer-reviewed publication”? Why not just post it on bioRxiv and leave it to any of the free review servers? Or post it on one’s own website and open a comment thread?

In bistable perception triggered by ambiguous images, often one of the two perceptual interpretations is more prevalent, reflecting an individual-specific long-term prior that is stable over time. E.g., people tend to perceive the Necker cube as viewed from the top more often.

In sum, while hippocampus/MTL is central to one-shot learning in episodic memory ('where did I park my car this morning?'), it is not needed for one-shot perceptual learning. One-shot perceptual learning does not depend on conscious remembering or the MTL.

These results suggest that long-range corticocortical feedback can underlie long-term priors' influence on perception, and inform future theories about the role of priors in perception.

@hakwanlau @thandrillon @ADemertzi @theASSC @ASSC27tokyo @kanair Whether you like the theory or not, and the people or not, IIT has inspired beautiful experiments such as those of Massimini’s. The core of the theory might not be empirically testable yet, but how do you test the “pointer” idea in your theory, Hakwan?

Our findings strongly support the 'informational bottleneck' hypothesis. Moreover, the length of neural integration of sensory history correlates with an individual subject's predictive performance. This provides an individual-based neural marker of naturalistic prediction. 5/6

A computational model incorporating hierarchical-predictive-coding and attractor-network elements reproduced both behavioral and neural findings. In this model, a bias at the top level propagates down the hierarchy, and a prediction error signal propagates up.

3) When a phase-scrambled image was presented, participants sometimes experienced false perceptions, accompanied by enhanced ACC/IFJ activation & DMN deactivation, all with decodable information. These regions may subserve top-down inference under increased sensory uncertainty.

Using resting-state activity and pre-stimulus baseline during task, we found that spontaneous pupil size fluctuations co-varied with cortical activity power in most frequency bands across multiple large-scale resting-state networks.

Together, these results reveal rich and heterogeneous representational dynamics across large-scale brain networks during conscious visual object recognition when sensory input has a relatively high level of uncertainty. We thank the support by @NIHFunding and @NYULH_Neuro .

We presented visual images at a participant’s perceptual threshold, such that the same image, when repeatedly presented, is sometimes consciously recognized and at other times not. We used 7T fMRI to record brain activity and probe the underlying neural mechanisms. Key findings:

Dynamical stimuli in natural environments contain temporal correlations over a range of time scales, manifesting as 1/f-type power spectra. How humans exploit such natural statistical regularities to make predictions remains unknown. 2/6

Another point I should have highlighted: We used a novel state space analysis approach to simultaneously extract multivariate neural patterns supporting different behavioral metrics in the same task. This method can be easily adapted to other tasks. Read our paper to learn more!

The above findings were obtained with relatively slow fluctuations of pupil size. Fast, momentary pupil constriction/dilation also correlated with MEG activity, with time courses similar to single-unit findings in animal models, although without significant effects on behavior.

Recognition outcome could be reliably decoded from MEG signals starting at 200 ms after image onset, long before significant decoding of stimulus category at 470 ms. Such late emergency of category information is very different from that observed during "core object recognition".

Pre-stimulus cortical power unrelated to pupil size fluctuations also significantly predicted perceptual behavior, suggesting that pupil/arousal-independent spontaneous cortical activity influences perception.

1) Visual images, whether consciously recognized or not, (de)activate similar large-scale (cortical and subcortical) brain networks, with almost the same spatial extent. This suggests that the key neural mechanism for conscious recognition is not recruitment of additional areas.

2) Information about recognition content could be decoded from activity patterns in ~all of the activated and deactivated cortical regions, but not subcortical regions. In unrecognized trials, neither the stimulus nor the reported category was decodable in the same brain regions.
