The Normalization Model of Attention

Open access
Reynolds, John H., Heeger, David J.·2009·Neuron

Abstract

Attention has been found to have a wide variety of effects on the responses of neurons in visual cortex. We describe a model of attention that exhibits each of these different forms of attentional modulation, depending on the stimulus conditions and the spread (or selectivity) of the attention field in the model. The model helps reconcile proposals that have been taken to represent alternative theories of attention. We argue that the variety and complexity of the results reported in the literature emerge from the variety of empirical protocols that were used, such that the results observed in any one experiment depended on the stimulus conditions and the subject's attentional strategy, a notion that we define precisely in terms of the attention field in the model, but that has not typically been completely under experimental control.

  • Gain modulation (wherein attention multiplicatively scales neural activity) has been found in many neural systems.

    “Similar to self-attention, gain modulation (wherein attention multiplicatively scales neural activity) has been found in many neural systems (Treue & Trujillo 1999, Reynolds & Heeger 2009).”

    The Introduction reports studies in which attention multiplicatively increases neuronal responses, and the section on spatial attention describes scaling in visual cortical areas V4 and MT. The paper reviews visual cortex, however, so it does not establish the broader claim that this effect has been found in many neural systems; it also notes other forms of attentional modulation. (LLM, conf=0.84)

  • Multiplicative amplitude modulations of response tuning functions preserve feature selectivity.

    “Particularly interesting are multiplicative amplitude modulations of the response tuning function since they preserve feature selectivity”

  • Neurons in many cortical and subcortical brain areas exhibit robust gain modulation that may contribute to multiple cognitive functions, including attention, learning, sensory processing and multimodal integration.

    “Neurons in many cortical and subcortical brain areas exhibit robust gain modulation that may contribute to multiple cognitive functions, including attention, learning, sensory processing and multimodal integration1–3,7,8,13–17.”

  • In non-human primate visual system, visual spatial attention within the receptive field of a recorded neuron enhances both contrast gain and response gain.

    “Attentional modulation of neural gain has been particularly well studied in the non-human primate visual system1,42,43, in which visual spatial attention within the receptive field of a recorded neuron enhances both contrast gain (that is, scaling of that neuron’s stimulus-response relationship along the contrast axis)43 and response gain (that is, multiplicative transformation of responses to all”

  • Attention produces widespread effects throughout early and late visual areas, increasing the signal from the attended item and suppressing noise from unattended distractors.

    “These studies have shown that attention produces widespread effects throughout early and late visual areas, which collectively increase the signal from the attended item and suppress noise from unattended distractors (Reynolds and Heeger, 2009).”

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.
