Abstract

Significance: When a visual stimulus repeats multiple times, visual cortical neurons show decreasing firing rate responses, yet neither perception nor stimulus-related behavior is compromised. We show that stimulus repetition leads to increased neuronal gamma-band (∼40–90 Hz) synchronization within and between early and higher visual areas. The enhanced gamma-band synchronization likely maintains effective stimulus signaling in the face of dwindling firing rates. We also show that synchronization to the gamma rhythm increases for spikes in general and for those of putative interneurons, whereas it decreases for spikes of putative excitatory neurons if they are not strongly stimulus-driven. Thus, inhibitory interneurons might create increasingly precise gamma-band synchronization, and thereby prune the stimulus representation by pyramidal cells to be sparser and more efficient.

  • In previous studies where stimulus repetition was not behaviorally relevant, gamma-band power and synchronization in visual cortex increased with repetition.

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.
