  • Title: Attentional cueing reverses deficits in spatial working memory task performance in chronic low dose MPTP-treated monkeys.
    Author: Decamp E, Tinker JP, Schneider JS.
    Journal: Behav Brain Res; 2004 Jul 09; 152(2):259-62. PubMed ID: 15196793.
    Abstract:
    Chronic low dose MPTP-treated monkeys develop difficulty in performing spatial working memory tasks. Since these tasks have both attentional and memory components, the extent to which task performance deficits are attentional or memory in nature was examined. Using a modified variable delayed response (VDR) task, employment of an attentional cue prior to stimulus presentation significantly improved task performance, suggesting a strong attentional component to the deficit in spatial working memory task performance. These findings suggest that procedures to enhance attention may be useful in ameliorating some of the "memory" deficits associated with early Parkinson's disease.
