Selective D2 receptor actions on the functional circuitry of working memory

Wang, Min, Vijayraghavan, Susheel, Goldman-Rakic, Patricia S.·2004·Science

Abstract

Prefrontal neurons engaged by working memory tasks express a sequence of phasic and tonic activations linked to a train of sensory, mnemonic, and response-related events. Here, we report that the dopamine D2 receptor selectively modulates the neural activities associated with memory-guided saccades in oculomotor delayed-response tasks yet has little or no effect on the persistent mnemonic-related activity, which is instead modulated by D1 receptors. This associates the D2 receptor with a specific component of working memory circuitry and fractionates the modulatory effects of D1 and D2 receptors on the neural machinery of a cognitive process.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • D2-receptors in the PFC are concentrated in layer V neurons where they increase response-related firing.

    “D2-receptors in the PFC are concentrated in layer V neurons where they also increase response-related firing (Wang et al., 2004).”
  • Excessive D2 receptor stimulation impairs prefrontal cortex working memory function in animals and humans and is associated with increased response-related firing in monkeys and increased response-related blood oxygen level-dependent signals in human imaging studies.

    “excessive D2 receptor stimulation impairs PFC working memory function in animals69 and humans70 and is associated with increased response-related firing in monkeys71 and increased response-related blood oxygen level-dependent signals in human imaging studies70.”
  • Iontophoresis of D2 drugs onto PFC neurons has no effect on delay cell firing during the delay period in a working memory task but has marked effects on response cell firing in relationship to the eye movement response.

    “Iontophoresis of D2 drugs onto PFC neurons has no effect on delay cell firing during the delay period in a working memory task but has marked effects on response cell firing in relationship to the eye movement response (124).”
  • In contrast to delay cells, layer V sensory-motor response cells in dlPFC show increased firing with high levels of dopamine D2 receptor stimulation.

    “In contrast to delay cells, which reduce firing with high levels of dopamine D1R stimulation, layer V sensory-motor response cells in dlPFC show increased firing with high levels of dopamine D2 receptor stimulation63.”

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.
