Multiple Mechanisms for Contrast Adaptation in the Retina

Open access
Demb, Jonathan B.·2002·Neuron

Abstract

The retina adapts to average light intensity but also to the range of light intensities (contrast). A study by Baccus and Meister, in this issue of Neuron, identifies three ways that ganglion cells and interneurons adapt to high contrast: shorten integration time, reduce gain, and depolarize. Only the depolarization decays, over tens of seconds.

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

Claims the paper makes

We couldn’t retrieve this paper’s full text, 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?

  • Adaptation enables high sensitivity to small changes in stimulus features over a large range of intensities and is found across sensory systems.

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.
