Normalization of cell responses in cat striate cortex

Heeger, David J.·1992·Visual Neuroscience

Abstract

Simple cells in the striate cortex have been depicted as half-wave-rectified linear operators. Complex cells have been depicted as energy mechanisms, constructed from the squared sum of the outputs of quadrature pairs of linear operators. However, the linear/energy model falls short of a complete explanation of striate cell responses. In this paper, a modified version of the linear/energy model is presented in which striate cells mutually inhibit one another, effectively normalizing their responses with respect to stimulus contrast. This paper reviews experimental measurements of striate cell responses, and shows that the new model explains a significantly larger body of physiological data.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • The spatial quality in (3) is closely related to contrast gain control models that use divisive normalization to model the response properties of neurons in the primary visual cortex.

    “The spatial quality in (3) is closely related to contrast gain control models that use divisive normalization to model the response properties of neurons in the primary visual cortex [65], [67], [66].”
  • The constants C1, C2, C3 serve to stabilize the computation in regions of low signal energy and are included in most divisive normalization models.

    “The constants serve to stabilize the computation in these regions and are included in most divisive normalization models [65], [67], [24], [64], [68].”

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.
