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 functional magnetic resonance imaging study of frontal networks in obsessive-compulsive disorder during cognitive reappraisal
Cambridge University Press (2022-10-03)Background Patients with obsessive-compulsive disorder (OCD) present difficulties in the cognitive regulation of emotions, possibly because of inefficient recruitment of distributed patterns of frontal cortex regions. The ... -
A Semantic Cognition Contribution to Mood and Anxiety Disorder Pathophysiology
MDPI (2023)Over the last two decades, the functional role of the bilateral anterior temporal lobes (bATLs) has been receiving more attention. They have been associated with semantics and social concept processing, and are regarded ... -
Abstinence duration modulates striatal functioning during monetary reward processing in cocaine patients
Wiley (2013)Pre-clinical and clinical studies in cocaine addiction highlight alterations in the striatal dopaminergic reward system that subserve maintenance of cocaine use. Using an instrumental conditioning paradigm with monetary ... -
Altered frontoparietal connectivity in patients with obsessive-compulsive disorder during an fMRI cognitive reappraisal task
Elsevier (2022-10)Patients with obsessive-compulsive disorder (OCD) present increased brain activity in orbitofrontal and limbic regions when experiencing negative emotions, which could be related to deficits in emotion regulation abilities. ... -
Anticipatory cues in emotional processing shift the activation of a combined salience sensorimotor functional network in drug-naïve depressed patients
Elsevier (2022-10-22)Background Major depressive disorder is characterized by a large-scale brain network dysfunction, contributing to impairments in cognitive and affective functioning. Core regions of default mode, limbic and salience ... -
Bilingualism's Effects on Resting-State Functional Connectivity in Mild Cognitive Impairment
Mary Ann Liebert (2021-01-21)Background: Bilingualism is considered a cognitive reserve (CR) factor, due to the delay in the onset of dementia in bilinguals compared with monolinguals. Two neural mechanisms have been suggested to underlie CR: neural ... -
Brain networks alterations in cocaine use and gambling disorders during emotion regulation
Akadémiai Kiadó (2022)Background: Cocaine use disorder (CUD) and gambling disorder (GD) share clinical features and neural alterations, including emotion regulation deficits and dysfunctional activation in related networks. However, they also ... -
Brain networks involved in accented speech processing
Elsevier (2019-07)We investigated the neural correlates of accented speech processing (ASP) with an fMRI study that overcame prior limitations in this line of research: we preserved intelligibility by using two regional accents that differ ... -
Cambios estructurales y funcionales en el Lóbulo Temporal Medial como consecuencia del aprendizaje de palabras: un estudio longitudinal mediante fMRI
Universitat Jaume I (2014-07-21)El córtex rinal desempeña un papel esencial en la codificación inicial y posterior expresión de asociaciones de memoria a largo plazo. Estudios de aprendizaje en animales y humanos han demostrado que la actividad de esta ... -
Comparison of two fMRI tasks for the evaluation of the expressive language function
Springer-Verlag (2010-05)Presurgical evaluation of language is important in patients who are candidates for neurosurgery since language decline is a frequent complication after an operation. Different functional magnetic resonance imaging (fMRI) ... -
Differential dorsolateral prefrontal cortex activation during a verbal n-back task according to sensory modality
Elsevier (2009)Functional neuroimaging studies carried out on healthy volunteers while performing different n-back tasks have shown a common pattern of bilateral frontoparietal activation, especially of the dorsolateral prefrontal cortex ... -
Differential neural control in early bilinguals and monolinguals during response inhibition
Elsevier (2014-05)We tested the hypothesis that early bilinguals and monolinguals use different brain areas when performing nonlinguistic executive control tasks. For this, we explored brain activity of early bilinguals and monolinguals ... -
Dissociating the semantic function of two neighbouring subregions in the left lateral anterior temporal lobe
Elsevier (2015)We used fMRI in 35 healthy participants to investigate how two neighbouring subregions in the lateral anterior temporal lobe (LATL) contribute to semantic matching and object naming. Four different levels of processing ... -
Do bilinguals show neural differences with monolinguals when processing their native language?
Elsevier (2015-03)The present research used fMRI to measure brain activity in passive listening and picture-naming tasks with a group of early high proficient Spanish–Catalan bilinguals, in which Spanish was dominant, and a group of Spanish ... -
Emotion regulation deficits in euthymic bipolar I versus bipolar II disorder: a functional and diffusion-tensor imaging study
John Wiley & Sons Ltd. (2015-03-15)Objectives Emotion regulation deficits are a core feature of bipolar disorder. However, their potential neurobiological underpinnings and existence beyond bipolar I disorder remain unexplored. Our main goal was to investigate ... -
Functional Connectivity Between Superior Parietal Lobule and Primary Visual Cortex “at Rest” Predicts Visual Search Efficiency
Mary Ann Liebert (2015)Spatiotemporal activity that emerges spontaneously “at rest” has been proposed to reflect individual a priori biases in cognitive processing. This research focused on testing neurocognitive models of visual attention by ... -
Gray Matter and Functional Connectivity in Anterior Cingulate Cortexare Associated with the State of Mental Silence During Sahaja YogaMeditation
Elsevier (2018)Abstract—Some meditation techniques teach the practitioner to achieve the state of mental silence. The aim ofthis study was to investigate brain regions that are associated with their volume and functional connectivity(FC) ... -
Inferior frontal cortex activity is modulated by reward sensitivity and performance variability
Elsevier (2016-01)High reward sensitivity has been linked with motivational and cognitive disorders related with prefrontal and striatal brain function during inhibitory control. However, few studies have analyzed the interaction among ... -
