    • Alpha-Band Hypersynchronization in Progressive Mild Cognitive Impairment: A Magnetoencephalography Study 

      López, María Eugenia; Bruna, Ricardo; Aurtenetxe, Sara; Pineda-Pardo, José Ángel; Marcos, Alberto; Arrazola, Juan; Reinoso, Ana Isabel; Montejo, Pedro; Bajo, Ricardo ; Maestú, Fernando (Journal of Neuroscience, 10/2014)
      People with mild cognitive impairment (MCI) show a high risk to develop Alzheimer's disease (AD; Petersen et al., 2001). Nonetheless, there is a lack of studies about how functional connectivity patterns may distinguish ...

    • Cognitive reserve is associated with the functional organization of the brain in healthy aging: a MEG study 

      López, María Eugenia; Aurtenetxe, Sara; Pereda, Ernesto; Cuesta, Pablo; Castellanos, Nazareth; Bruna, Ricardo; Niso, Guiomar; Maestú, Fernando; Bajo, Ricardo (Frontiers in Aging Neuroscience, 06/2014)
      The proportion of elderly people in the population has increased rapidly in the last century and consequently "healthy aging" is expected to become a critical area of research in neuroscience. Evidence reveals how healthy ...

    • Differential Patterns of Connectivity in Progressive Mild Cognitive Impairment 

      Bajo, Ricardo ; Castellanos, Nazareth; Cuesta, Pablo; Aurtenetxe, Sara; Garcia-Prieto, Juan; Gil-Gregorio, Pedro; del pozo, Francisco; Maestú, Fernando (Brain Connectivity, 05/2012)
      It is now widely accepted that Alzheimer's disease is characterized by a functional disconnection between brain regions. The disease appears to begin up to decades prior to clinical diagnosis. Therefore, in the present ...

    • Drug polyconsumption is associated with increased synchronization of brain electrical-activity at rest and in a counting task 

      Coullaut-Valera, R; Arbaiza, I; Bajo, Ricardo ; Arrue, R; López, ME; Collaut-Valera, J; Correas, A; López-Sanz, D; Maestú, Fernando; Papo, D (International Journal of Neural Systems, 02/2014)
      Drug abusers typically consume not just one but several types of drugs, starting from alcohol and marijuana consumption, and then dramatically lapsing into addiction to harder drugs, such as cocaine, heroin, or amphetamine. ...

    • Synchronization during an internally directed cognitive state in healthy aging and mild cognitive impairment: a MEG study 

      López, María Eugenia; Garcés, Pilar; Cuesta, Pablo; Castellanos, Nazareth; Aurtenetxe, Sara; Bajo, Ricardo ; Marcos, Alberto; Montenegro, Mercedes; Yubero, Raquel; del pozo, Francisco; Sancho, Miguel; Maestú, Fernando (AGE, 06/2014)
      Mild cognitive impairment (MCI) is a stage between healthy aging and dementia. It is known that in this condition the connectivity patterns are altered in the resting state and during cognitive tasks, where an extra effort ...
