Frontiers (2013)Brain tumors can have different shapes or locations, making their identification very challenging. In functional MRI, it is not unusual that patients have only one anatomical image due to time and financial constraints. ... -

Bilinguals use language-control brain areas more than monolinguals to perform non-linguistic switching tasks
Rodríguez Pujadas, Aina; Sanjuán Tomás, Ana; Ventura Campos, Mercedes; Martín, Clara; Barceló, Francisco; Costa, Albert; Román Fernández, Patricia; Avila, Cesar Public Library of Science (2013)We tested the hypothesis that early bilinguals use language-control brain areas more than monolinguals when performing non-linguistic executive control tasks. We do so by exploring the brain activity of early bilinguals ... -
Bridging language and attention: Brain basis of the impact of bilingualism on cognitive control
Garbin, Gabrielle; Sanjuán Tomás, Ana; Forn, Cristina; Bustamante, Juan Carlos; Rodríguez Pujadas, Aina; Belloch, Vicente; Hernández, Mireia; Costa, Albert; Avila, Cesar 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 ... -
Comparison of two fMRI tasks for the evaluation of the expressive language function
Sanjuán Tomás, Ana; Bustamante, Juan Carlos; Forn, Cristina; Ventura Campos, Mercedes; Barrós-Loscertales, Alfonso; Martínez, Juan Carlos; Villanueva, Vicente 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 neural control in early bilinguals and monolinguals during response inhibition
Rodríguez Pujadas, Aina; Sanjuán Tomás, Ana; Fuentes-Claramonte, Paola; Ventura Campos, Mercedes; Barrós-Loscertales, Alfonso; Avila, Cesar 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
Sanjuán Tomás, Ana; Hope, Thomas M.H.; Parker Jones, 'Ōiwi; Prejawa, Susan; Oberhuber, Marion; Guerin, Julie; Seghier, Mohamed L.; Green, David W.; Price, Cathy J. 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?
Palomar-García, María-Ángeles; Bueichekú, Elisenda; Avila, Cesar; Sanjuán Tomás, Ana; Strijkers, Kristof; Ventura Campos, Mercedes; Costa, Albert 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 ... -
