Age-related changes in brain activity are specific for high order cognitive processes during successful encoding of information in working memory
(Frontiers Media, 2015)Memory capacity suffers an age-related decline, which is supposed to be due to a generalized slowing of processing speed and to a reduced availability of processing resources. Information encoding in memory has been ... -
Age-related effects on event-related brain potentials in a congruence/incongruence judgment color-word Stroop task
(Frontiers Media, 2014)We examined the event-related brain potentials elicited by color-word stimuli in a Stroop task in which healthy participants (young and old) had to judge whether the meaning and the color of the stimulus were congruent or ... -
An Event Related Potentials Study of the Effects of Age, Load and Maintenance Duration on Working Memory Recognition
(PLOS, 2015-11-16)Age-related decline in cognitive capacities has been attributed to a generalized slowing of processing speed and a reduction in working memory (WM) capacity. Nevertheless, it is unclear how age affects visuospatial WM ... -
Assessing mild behavioral impairment with the mild behavioral impairment checklist in people with subjective cognitive decline
(Cambridge University Press, 2018-04-04)Objectives: To estimate the prevalence of Mild Behavioral Impairment (MBI) in people with Subjective Cognitive Decline (SCD), and validate the Mild Behavioral Impairment Checklist (MBI-C) with respect to score distribution, ... -
Assessing Mild Behavioral Impairment with the Mild Behavioral Impairment-Checklist in People with Mild Cognitive Impairment
(IOS Press, 2018-08-01)Background: Neuropsychiatric symptoms (NPS) are non-cognitive, behavioral, or psychiatric symptoms, common in mild cognitive impairment (MCI) and associated with a higher risk of dementia. Mild behavioral impairment (MBI) ... -
Brain dinamics associated with face-naming and the tip-of-the-tongue state
(Colegio Oficial de Psicólogos del Principado, 2011)Active brain areas and their temporal sequence of activation during the successful retrieval and naming of famous faces (KNOW) and during the tip-of-the-tongue (TOT) state were studied by means of low resolution ... -
Cognitive control activity is modulated by the magnitude of interference and pre-activation of monitoring mechanisms
(Nature Publishing Group, 2016-12-20)The Simon task is used to study interference from irrelevant spatial information. Interference is manifested by longer reaction times when the required response –based on non-spatial features- is spatially incompatible ... -
Design of optimal nonlinear network controllers for Alzheimer's disease
(PLOS, 2018-05-24)Brain stimulation can modulate the activity of neural circuits impaired by Alzheimer's disease (AD), having promising clinical benefit. However, all individuals with the same condition currently receive identical brain ... -
Effects of aging and involuntary capture of attention on event-related potentials associated with the processing of and the response to a target stimulus
(Frontiers Media, 2014)The main aim of the present study was to assess whether aging modulates the effects of involuntary capture of attention by novel stimuli on performance, and on event-related potentials (ERPs) associated with target ... -
Effects of load and maintenance duration on the time course of information encoding and retrieval in working memory: from perceptual analysis to post-categorization processes
(Frontiers Media, 2014)Working memory (WM) involves three cognitive events: information encoding, maintenance, and retrieval; these are supported by brain activity in a network of frontal, parietal and temporal regions. Manipulation of WM load ... -
El nivel de vocabulario como indicador de reserva cognitiva en la evaluación del deterioro cognitivo ligero
(Universidad de Murcia, 2014)El presente trabajo estudia el papel del vocabulario, como indicador de reserva cognitiva,en la evaluación del Deterioro Cognitivo Ligero (DCL). Participaron 326 adultos mayores de 50 años, clasificados en dos ... -
Electrophysiological Correlates of Amnestic Mild Cognitive Impairment in a Simon Task
(PLoS, 2013-12-05)Amnestic mild cognitive impairment (aMCI) represents a prodromal stage of Alzheimer`s disease (AD), especially when additional cognitive domains are affected (Petersen et al., 2009). Thus, single-domain amnestic MCI (sdaMCI) ... -
Event-related brain potential indexes provide evidence for some decline in healthy people with subjective memory complaints during target evaluation and response inhibition processing
(Elsevier, 2021)In the preclinical stage of the Alzheimer’s disease (AD) continuum, subjects report subjective memory complaints (SMCs), although with the absence of any objective decline, and have a higher risk of progressing to dementia ... -
Factores de estado de ánimo precompetitivo en adolescentes de deportes colectivos y satisfacción con el rendimiento
(Universitat de les Illes BalearsUniversitat Autònoma de Barcelona, 2016)Esta investigación estuvo guiada por el modelo teórico de Lane y Terry (2000) y se realizó con el objetivo de estudiar el perfil de estado de ánimo en deportistas adolescentes, así como su vínculo con el rendimiento posterior ... -
First-time admissions for opioid treatment: crosssectional and descriptive study of new opioid users seeking treatment
(Dove Medical Press, 2015)Background: The purpose of this study was to gain an understanding of the profiles of the new treatment demands posed by opioid addicts between 2005 and 2010 at the addictive disorders assistance units in Galicia, ... -
Functional Equivalence of Imagined vs. Real Performance of an Inhibitory Task: An EEG/ERP Study
(Frontiers Media, 2016-09-16)Early neuroimaging and electrophysiological studies suggested that motor imagery recruited a different network than motor execution. However, several studies have provided evidence for the involvement of the same circuits ... -
Increased neural noise and impaired brain synchronization in fibromyalgia patients during cognitive interference
(Springer Nature, 2017)Fibromyalgia (FM) and other chronic pain syndromes are associated with cognitive dysfunction and attentional deficits, but the neural basis of such alterations is poorly understood. Dyscognition may be related to high ... -
Inhibition deficit in the spatial tendency of the response in multiple-domain amnestic mild cognitive impairment. An event-related potential study
(Frontiers Media, 2015)Longitudinal studies have shown that a high percentage of people with amnestic mild cognitive impairment (MCI) develop Alzheimer’s disease (AD). Prodromal AD is known to involve deficits in executive control processes. In ... -
Involuntary capture and voluntary reorienting of attention decline in middle-aged and old participants
(Frontiers Media, 2016-03-30)The main aim of this study was to examine the effects of aging on event-related brain potentials (ERPs) associated with the automatic detection of unattended infrequent deviant and novel auditory stimuli (Mismatch ... -
