This study examined verbal and nonverbal aspects of explicit and implicit memory in a sample of 19 Parkinson's disease (PD) patients and 21 control subjects. For implicit memory evaluation, we used a Mirror Reading (MR) task employing verbal material as well as a nonverbal Serial Reaction Time (SRT) task. For explicit memory measurement we applied a word(More)
Local and regulated expression of exogenous genes in the central nervous system is one of the major challenges of modern neuroscience. We have approached this issue by applying the inducible tetracycline system to regulate the expression of EGFP reporter gene in double transgenic rats. We have obtained a strong induction of EGFP only in male testes, which(More)
Several functional neuroimaging studies in patients with Parkinson's disease (PD) have suggested that changes in the fronto-parietal-striatal networks are associated with deficits in executive functioning. However, executive functions (EF) are multifaceted and include three dissociable components: working memory, response inhibition, and task-switching.(More)
Deficits in facial emotion recognition in Parkinson's disease (PD) patients has been well documented. Nevertheless, it is still not clear whether facial emotion recognition deficits are secondary to other cognitive impairments. The aim of this study was to answer the question of whether deficits in facial emotion recognition in PD result from impaired(More)
Mild cognitive impairment (MCI) is present in on average one-fourth of Parkinson's disease (PD) patients with no dementia diagnosis. Only recently has PD-MCI been treated as a new diagnostic entity. In 2012, unified criteria were adopted which allow both diagnosing MCI in Parkinson's disease (PD-MCI) and further classification taking into account the(More)
