Abstract

A local field potential (LFP) response can be measured throughout the visual cortex in response to the abrupt appearance of a visual stimulus. Averaging LFP responses to many stimulus presentations isolates transient, phase-locked components of the response that are consistent from trial to trial. However, stimulus responses are also composed of sustained components, which differ in their phase from trial to trial and therefore must be evaluated using other methods, such as computing the power of the response of each trial before averaging. Here, we investigate the basis of phase-locked and non-phase-locked LFP responses in the primary visual cortex of the macaque monkey using a novel variant of current source density (CSD) analysis. We applied a linear array of electrode contacts spanning the thickness of the cortex to measure the LFP and compute band-limited CSD power to identify the laminar sites of persistent current exchange that may be the basis of sustained visual LFP responses. In agreement with previous studies, we found a short-latency phase-locked current sink, thought to correspond to thalamocortical input to layer 4C. In addition, we found a prominent non-phase-locked component of the CSD that persisted as long as the stimulus was physically present. The latter was relatively broadband, lasted throughout the stimulus presentation, and was centered ∼500 μm deeper than the initial current sink. These findings demonstrate a fundamental difference in the neural mechanisms underlying the initial and sustained processing of simple visual stimuli in the V1 microcircuit.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Prediction error signals should rapidly decay as inference is formed.

    “prediction error signals should rapidly decay as inference is formed”

    From How Do Expectations Shape Perception? (2018) · cites this paper as [129]

    The Introduction says phase-locked visual responses typically decay after a few hundred milliseconds, supporting the rapid-decay aspect. It does not identify those responses as prediction error signals or link their decay to inference being formed. (LLM, conf=0.79)

    Experimental — accuracy not yet measured
  • Confirmed prediction signals should remain stable.

    “while confirmed prediction signals should remain stable [129]”

    From How Do Expectations Shape Perception? (2018) · cites this paper as [129]

    The Results section on electrode positioning describes stable recordings and electrode placement, while the Results on sustained CSD responses describe visual-stimulus activity. Searches for confirmed predictions, prediction-error signals, and expected stimuli found no passage addressing whether confirmed prediction signals should remain stable. No page numbers were provided for these passages. (LLM, conf=0.74)

    Experimental — accuracy not yet measured

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.
