Aberrant Brain Plasticity in Autism Spectrum Disorders
Oberman, Lindsay M.; Rotenberg, Alexander; Pascual-Leone, Alvaro (Oxford University Press, 2014)Plasticity enables the human brain to adapt to developmental challenges and rapidly changing environmental demands, acquire new skills, and cope with injury. However, aberrant or mistimed brain plasticity can lead to ... -

Oliveri, Massimiliano; Finocchiaro, Chiara; Shapiro, Kevin Alfred; Gangitano, Massimo; Caramazza, Alfonso; Pascual-Leone, Alvaro (Massachusetts Institute of Technology Press, 2004)A number of researchers have proposed that the premotor and motor areas are critical for the representation of words that refer to actions, but not objects. Recent evidence against this hypothesis indicates that the left ... -
APOE Status Modulates the Changes in Network Connectivity Induced by Brain Stimulation in Non-Demented Elders
Peña-Gomez, Cleofé; Solé-Padullés, Cristina; Clemente, Imma C.; Junqué, Carme; Bargalló, Núria; Bosch, Beatriz; Molinuevo, José Luis; Valls-Solé, Josep; Pascual-Leone, Alvaro; Bartrés-Faz, David (Public Library of Science, 2012)Behavioral consequences of a brain insult represent an interaction between the injury and the capacity of the rest of the brain to adapt to it.

Assessing brain plasticity across the lifespan with transcranial magnetic stimulation: why, how, and what is the ultimate goal?
Freitas, Catarina; Farzan, Faranak; Pascual-Leone, Alvaro (Frontiers Media S.A., 2013)Sustaining brain and cognitive function across the lifespan must be one of the main biomedical goals of the twenty-first century.

During functional magnetic resonance imaging (fMRI), volunteers saw emotional and neutral expectancy cues signaling the ... -
Brain Plasticity in Blind Subjects Centralizes Beyond the Modal Cortices
Ortiz-Terán, Laura; Ortiz, Tomás; Perez, David L.; Aragón, Jose Ignacio; Diez, Ibai; Pascual-Leone, Alvaro; Sepulcre, Jorge (Frontiers Media S.A., 2016)It is well established that the human brain reorganizes following sensory deprivations. In blind individuals, visual processing regions including the lateral occipital cortex (LOC) are activated by auditory and tactile ... -

Farzan, Faranak; Vernet, Marine; Shafi, Mouhsin M. D.; Rotenberg, Alexander; Daskalakis, Zafiris J.; Pascual-Leone, Alvaro (Frontiers Media S.A., 2016)The concurrent combination of transcranial magnetic stimulation (TMS) with electroencephalography (TMS-EEG) is a powerful technology for characterizing and modulating brain networks across developmental, behavioral, and ... -

The compensatory dynamic of inter-hemispheric interactions in visuospatial attention revealed using rTMS and fMRI
Plow, Ela B.; Cattaneo, Zaira; Carlson, Thomas A.; Alvarez, George A.; Pascual-Leone, Alvaro; Battelli, Lorella (Frontiers Media S.A., 2014)A balance of mutual tonic inhibition between bi-hemispheric posterior parietal cortices is believed to play an important role in bilateral visual attention. However, experimental support for this notion has been mainly ... -
Complex mechanisms linking neurocognitive dysfunction to insulin resistance and other metabolic dysfunction
Stoeckel, Luke E.; Arvanitakis, Zoe; Gandy, Sam; Small, Dana; Kahn, C. Ronald; Pascual-Leone, Alvaro; Pawlyk, Aaron; Sherwin, Robert; Smith, Philip (F1000Research, 2016)Scientific evidence has established several links between metabolic and neurocognitive dysfunction, and epidemiologic evidence has revealed an increased risk of Alzheimer’s disease and vascular dementia in patients with ... -
