A comparison of brain activation patterns during covert and overt paced auditory serial addition test tasks
Wiley (2008-06)The Paced Auditory Serial Addition test (PASAT) is a sensitive task for evaluating cognitive impairment in patients with diffuse brain disorders, such as multiple sclerosis patients. Brain areas involved in this task have ... -
A cross-sectional and longitudinal study on the protective effect of bilingualism against dementia using brain atrophy and cognitive measures.
Springer (2020-01-10)Background: Evidence from previous studies suggests that bilingualism contributes to cognitive reserve because bilinguals manifest the first symptoms of Alzheimer’s disease (AD) up to 5 years later than monolinguals. ... -
A Symbol Digit Modalities Test version suitable for functional MRI studies
Elsevier (2009)The Symbol Digit Modalities Test is an easy test used to assess cognitive impairment in a wide range of neurological diseases, like multiple sclerosis. We adapted the oral version of this cognitive task making it suitable ...

Anatomical and functional differences between the Paced Auditory Serial Addition Test and the Symbol Digit Modalities Test
Psychology Press (2010)The Paced Auditory Serial Addition Test (PASAT) and the Symbol Digit Modalities Test (SDMT) are generally used to detect cognitive impairments in multiple sclerosis patients. Although both seem to be sensitive to the slow ...

Bridging language and attention: Brain basis of the impact of bilingualism on cognitive control
Elsevier (2010)Using two languages on an everyday basis appears to have a positive effect on general-purpose executive control in bilinguals. However, the neural correlates of this effect remain poorly understood. To investigate the brain ...

Un caso de síndrome de mano ajena fronto-calloso
Universitat Jaume I (2001)Diferentes estudios teóricos (Feinberg, y cols., 1992; Baynes y cols. 1997; Doody y Jankovic 1992) han mostrado que el síndrome de la mano ajena (Brion y Jedynak 1972) puede tener dos manifestaciones que son: mano ajena ...

Complexity Analysis of Cortical Surface Detects Changes in Future Alzheimer’s Disease Converters
Wiley (2017-12)Alzheimer’s disease (AD) is a neurological disorder that creates neurodegenerative changes at several structural and functional levels in human brain tissue. The fractal dimension (FD) is a quantitative parameter that ...
-
Distance disintegration delineates the brain connectivity failure of Alzheimer's disease
Elsevier (2019-12-14)Alzheimer's disease (AD) is associated with brain network dysfunction. Network-based investigations of brain connectivity have mainly focused on alterations in the strength of connectivity; however, the network breakdown ...

Effects of bilingualism on white matter atrophy in mild cognitive impairment: a diffusion tensor imaging study
Wiley (2019-12-05)Background and purpose:Previous investigations show that bilinguals exhibitthe first symptoms of dementia 4–5 years later than monolinguals. Therefore,bilingualism has been proposed as a cognitive reserve mechanism. Recent ...

Frontostriatal response to set switching is moderated by reward sensitivity
Oxford University Press (2011)The reinforcement sensitivity theory (RST) relates individual differences in reward sensitivity to the activation of the behavioral approach system (BAS). Dopamine-related brain structures have been repeatedly associated ...

Learning and Memory Impairments in Patients with Minimal Hepatic Encephalopathy are Associated with Structural and Functional Connectivity Alterations in Hippocampus
Nature (2018)Patients with minimal hepatic encephalopathy (MHE) show mild cognitive impairment associated with alterations in attentional and executive networks. There are no studies evaluating the relationship between memory in MHE ...
-
Morphological and functional evaluation of visual disturbances in a bilateral hand allograft recipient
Elsevier (2010)Allograft recipients are exposed to risks owing to immunosuppression, and there is always the possibility that psychological issues interfere with the procedure's outcomes. An episode of blindness was suspected in a bilateral ...
-
Neural bases of language switching in high and early proficient bilinguals
Elsevier (2011-12)The left inferior frontal cortex, the caudate and the anterior cingulate have been proposed as the neural origin of language switching, but most of the studies were conducted in low proficient bilinguals. In the present ...

Neuroimagen y neurobiología de la adicción:un estudio sobre los cambios funcionales cerebrales en personas adictas a las cocaína
Universitat Jaume I (2004)El consumo crónica de cocaína produce una reducción de la dopamina en ciertas áreas cerebrales, provocando una alteración en este sistema. (Volkow y cols., 1999; Wu y cols., 1997). El objetivo de este trabajo es estudiar ...

Reduced resting state connectivity and gray matter volume correlate with cognitive impairment in minimal hepatic encephalopathy
Public Library of Science (2017)Background and aims Minimal hepatic encephalopathy (MHE) is associated with cognitive alterations and changes in connectivity. We assessed the relationship of the abnormalities of resting-state functional connectivity ...
-
Reduced striatal volume in cocaine-dependent patients
Elsevier (2011)Long-term cocaine consumption is associated with brain structural and functional changes. While the animal literature on cocaine use and dependence has traditionally focused on the striatum, previous human studies using ...
