Abstract

Working memory (WM) activity is not as stationary or sustained as previously thought. There are brief bursts of gamma (~50–120 Hz) and beta (~20–35 Hz) oscillations, the former linked to stimulus information in spiking. We examined these dynamics in relation to readout and control mechanisms of WM. Monkeys held sequences of two objects in WM to match to subsequent sequences. Changes in beta and gamma bursting suggested their distinct roles. In anticipation of having to use an object for the match decision, there was an increase in gamma and spiking information about that object and reduced beta bursting. This readout signal was only seen before relevant test objects, and was related to premotor activity. When the objects were no longer needed, beta increased and gamma decreased together with object spiking information. Deviations from these dynamics predicted behavioral errors. Thus, beta could regulate gamma and the information in WM.

  • The balance between alpha/beta and gamma reflects the encoding, maintenance, and read-out of working memory.

    “The balance between alpha/beta and gamma reflect the encoding, maintenance, and read-out of working memory (56).”

    From Layer and rhythm specificity for predictive routing (2020) · cites this paper as [56]

    The Introduction and Discussion link the balance of beta and gamma bursting to working-memory encoding, maintenance, and readout. The paper discusses alpha as a possible analogous inhibitory rhythm, but does not establish an alpha/gamma balance across those stages. Page numbers are not available in the supplied passages.

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.
