A deficit in cognitive flexibility is acknowledged as a cognitive trait for obsessive-compulsive disorder (OCD). However, no investigations to date have used a cognitive activation paradigm to specify the neural correlates of this deficit in OCD. The objective of this study was to clarify how abnormal brain activities relate to cognitive inflexibility in OCD, using a task-switching paradigm. A ...

METHOD Participants were 457 twin pairs from the Colorado Learning Disabilities Research Center (CLDRC) twin study, an ongoing study of the etiology of RD, ADHD, and related disorders. Phenotypi...

Spatial working memory or short-term place memory is impaired in schizophrenia. The efficiency of antipsychotic drugs, particularly of typical antipsychotics, on cognitive deficit in schizophrenia remains disputable. Inhibition of serotonin (5-HT) 2A/2C receptors is important for cognitive improvement in schizophrenic patients treated with antipsychotics. The aim of the present work was to esta...

Caplan et al. (2007) have proposed that the sentence processing deficit in agrammatic aphasia is a consequence of intermittent deficiency (ID) in the capacity to carry out syntactic, semantic, and task-related computations. We operationalize ID as a specific impairment in a cognitive architecture for sentence processing. We also implement a complementary hypothesis of slowed processing (SP), wh...

To examine the effect of biflorin, a component of Syzygium aromaticum, on memory deficit, we introduced a scopolamine-induced cognitive deficit mouse model. A single administration of biflorin increased latency time in the passive avoidance task, ameliorated alternation behavior in the Y-maze, and increased exploration time in the Morris water maze task, indicating the improvement of cognitive ...

Parkinson's disease (PD), is a neurodegenerative illness, producing movement disorders, although it is also associated to cognitive deficit and emotional and behavioral alterations (Fuiza & Mayán, 2005; Vera-Cuesta et al., 2006), being prominent the presence of neuropsychological deficits among the majority of PD patients. The neuropsychological disorders can be observed from the very initial p...
