Abstract

Here we propose a model of how the visual brain segregates textured scenes into figures and background. During texture segregation, locations where the properties of texture elements change abruptly are assigned to boundaries, whereas image regions that are relatively homogeneous are grouped together. Boundary detection and grouping of image regions require different connection schemes, which are accommodated in a single network architecture by implementing them in different layers. As a result, all units carry signals related to boundary detection as well as grouping of image regions, in accordance with cortical physiology. Boundaries yield an early enhancement of network responses, but at a later point, an entire figural region is grouped together, because units that respond to it are labeled with enhanced activity. The model predicts which image regions are preferentially perceived as figure or as background and reproduces the spatio-temporal profile of neuronal activity in the visual cortex during texture segregation in intact animals, as well as in animals with cortical lesions.

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

  • Animal and human studies of vision support the hypothesis that predictive signals are sent from higher hierarchical levels predominantly via NMDA receptor signaling and prediction errors via AMPA receptors.

    “Animal and human studies of vision support this hypothesis (16–19).”

    From The Predictive Coding Account of Psychosis (2018) · cites this paper as [18]

    The Feedback Pathway describes signals fed back from higher to lower visual levels, and the Discussion says physiological findings support aspects of that feedback model. Neither passage addresses predictive signals or prediction errors, or assigns them to NMDA and AMPA receptors; searches for those terms found no relevant passage in our copy. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • Back projections may be important for visual awareness and beyond tasks such as visual categorization for perceptual organization and figure-ground segmentation or curve tracing.

    “In addition, back projections may be important for visual awareness and beyond tasks such as visual categorization for perceptual organization and figure-ground segmentation (48-50) or curve tracing (51).”

    From A feedforward architecture accounts for rapid categorization (2007) · cites this paper as [48]

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.
