Scopolamine affects short-term memory but not inferior temporal neurons

Miller, Earl K., Desimone, Robert·1993·NeuroReport

Abstract

Effects of scopolamine on performance of a delayed matching-to-sample task and on the properties of neurons in anterior-ventral inferior temporal (IT) cortex were examined in two monkeys. Both monkeys were impaired on the task after systemic administration of scopolamine, suggesting that scopolamine disrupts recency memory. Despite the behavioral deficit, neurons in IT cortex, a region having an important role in visual memory and neuronal properties consistent with that role, were largely unaffected by scopolamine. This dissociation between the behavioral and neuronal effects of scopolamine indicates that the drug either acts at a different site or disrupts unobserved mechanisms at the IT site.

  • Pharmacological blockade of muscarinic cholinergic receptors impairs performance in delayed match to sample tasks in non-human primates and humans.

    “This is consistent with some data showing that pharmacological blockade of muscarinic cholinergic receptors impairs performance in delayed match to sample tasks in non-human primates (Penetar and McDonough, 1983; Miller and Desimone, 1993) and humans (Robbins et al., 1997).”

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.
