Effects of excitotoxic lesions in the ventral striatopallidal-thalamocortical pathway on odor reversal learning: inability to extinguish an incorrect response

Ferry, Amon T., Lu, Xi-Chun M., Price, Joseph L.·2000·Experimental Brain Research

Abstract

The role of the ventral striatopallidal pathway and related cortical areas in stimulus-reward association reversal behavior was studied by inducing bilateral lesions with the excitotoxin, N-methyl-D-aspartate (NMDA) at restricted sites in the system. The areas lesioned were the ventral pallidum (VP), the ventral striatum (VS), the medial prefrontal cortex (mPFC) [i.e., the prelimbic (PL) and infralimbic (IL) cortexes], and the orbital cortex [i.e., the dorsolateral orbital (DLO), ventral lateral orbital (VLO), and lateral orbital (LO) cortexes]. Rats with lesions of the dorsal caudate nucleus and putamen (CPu) served as a positive control in this study. Water-deprived rats were trained on a go, no-go two-odor olfactory discrimination task to respond to one odor (S+) with water as a reward and to suppress responding to the other odor (S-). The rats were then tested for their ability to reverse the associated stimuli. The number of errors made before successfully learning the stimulus-reward association were measured in relation to a sham lesion control group which did not receive injections of NMDA. In experimental rats, the lesions did not affect their ability to learn stimulus-reward associations for novel odors, but did result in an increase in the number of false alarms after the significance of the associated stimuli were reversed. That is, the lesioned animals persisted in responding to the formerly rewarded but now unrewarded stimulus. Rats with damage to the CPu did no…

  • Lesions of the ventral striatum and pallidum, MD, or the OMPFC cause perseverative deficits in stimulus-reward reversal tasks in rats and monkeys.

    “In support of this hypothesis, lesions of the ventral striatum and pallidum, MD, or the OMPFC have been shown to cause perseverative deficits in stimulus-reward reversal tasks in rats and monkeys, such that the animals have difficulty switching away from previously rewarded, but now unrewarded stimuli (Roberts et al, 1990;McBride and Slotnick, 1997;Ferry et al, 2000a;Kazama and Bachevalier, 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.
