Abstract

One of the most fundamental functions of the brain is to predict upcoming events on the basis of the recent past. A closely related function is to signal when a prediction has been violated. The identity of the brain regions that mediate these functions is not known. We set out to determine whether they are implemented at the level of single neurons in the visual system. We gave monkeys prolonged exposure to pairs of images presented in fixed sequence so that each leading image became a strong predictor for the corresponding trailing image. We then monitored the responses of neurons in the inferotemporal cortex to image sequences that obeyed or violated the transitional rules imposed during training. Inferotemporal neurons exhibited a transitional surprise effect, responding much more strongly to unpredicted transitions than to predicted transitions. Thus, neurons even in the visual system make experience-based predictions and react when they fail.

  • Overall, stimuli that are expected evoke a reduced neural response.

    “Overall, stimuli that are expected evoke a reduced neural response.This pattern has been observed when stimuli are validly predicted by a preceding, arbitrarily paired, stimulus [65][66][67][68][69], when stimuli comply with a higher-order pattern such as a shape or scene [33,34], or when stimuli are the predictable result of an animal's own actions [70].”

    From How Do Expectations Shape Perception? (2018) · cites this paper as [67]

    The Results (page unavailable in our copy) show that predicted trailing images evoked weaker responses than unpredicted ones in monkey inferotemporal cortex. The claim generalizes this comparison to expected stimuli overall. The Discussion also says the study cannot determine whether the difference reflects suppression of predicted images or enhancement of unpredicted images. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Expectation suppression is observed in non-invasive fMRI BOLD and EEG/MEG signals, and in spike rates in non-human primates and rodents.

    “Moreover, expectation suppression is observed not only in non-invasive fMRI blood oxygen level-dependent (BOLD) [65,72,73] and electroencephalography (EEG)/magnetoencephalography (MEG) signals [68,69,77], but also in spike rates in non-human primates [66,67,74,76] and rodents [70,75,78].”

    From How Do Expectations Shape Perception? (2018) · cites this paper as [67]

    The Results report lower firing rates for predicted than unpredicted images in monkeys, supporting the non-human-primate spike-rate portion of the cited sentence. The Discussion says the study cannot determine whether this difference reflects suppression of predicted responses or enhancement of unpredicted responses, so it does not establish suppression specifically. This citation is attached to the primate portion, not the fMRI, EEG/MEG, or rodent claims. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • ES effects in macaque IT neurons emerge at early latencies (~150 ms).

    “These effects were sensitive to transitional statistics (e.g., the transition from Stimulus A to Stimulus B being more probable than from B to A), 90 , 91 persisted after controlling for RS, 88 , 89 and emerged at early latencies (∼150 ms). 88 , 90 , 91 , 92”

    From Evaluating the neurophysiological evidence for predictive processing as a model of perception (2020) · cites this paper as [90]

    The Results report that the transitional surprise signal in macaque IT neurons developed at a time statistically indistinguishable from the response to the unpredicted image; the Discussion says it was present from the outset of the visual response. Our copy does not give an onset latency of approximately 150 ms for that effect. The 150–250 ms window in the methods measures an LFP trough, not the effect’s onset. (LLM, conf=0.82)

  • Some studies have reported that expected stimulus representations are dampened.

    “some studies have reported that expected stimulus representations are dampened”

    From Evaluating the neurophysiological evidence for predictive processing as a model of perception (2020) · cites this paper as [90]

    The Results report weaker neuronal responses and less information about image identity for predicted than for unpredicted images. But the Discussion says the study cannot distinguish suppression of predicted-image responses from enhancement of unpredicted-image responses. It therefore supports a relative difference, not established dampening of expected representations. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Another possibility is that expectations have an anticipatory effect and sensitize representations even before stimulus onset.

    “Another possibility is that expectations have an anticipatory effect and sensitize representations even before stimulus onset.Empirical support for such forward-looking perceptual predictions comes from electrophysiological reports of stimulus-specific baseline shifts before stimulus onset [67,97], from time-locked responses to unexpectedly omitted stimuli [69,98], and from predictive preactiv”

    From How Do Expectations Shape Perception? (2018) · cites this paper as [67]

    The Fig. 3 caption reports prediction-related, image-pair-selective firing that persisted until the trailing image’s response began, supporting an anticipatory effect. But the Results describe changes in responses after image onset, not sensitization of the predicted image’s representation before onset; the Discussion leaves open whether prediction suppresses or enhances responses. Page numbers are unavailable in our copy. (LLM, conf=0.82)

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.
