    • Effects of age and working memory load on syntactic processing: An event-related potential study 

      Alatorre-Cruz, Graciela C; Silva-Pereyra, Juan; Fernandez, Thalia; Rodriguez-Camacho, Mario A; Castro Chavira, Susana Angelica; Sanchez-Lopez, Javier (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-04)
      Cognitive changes in aging include working memory (WM) decline, which may hamper language comprehension. An increase in WM demands in older adults would probably provoke a poorer sentence processing performance in this age group. A way to increase the WM load is to separate two lexical units in an agreement relation (i.e., adjective and noun), in a given sentence. To test this hypothesis, event-related ...

    • High levels of incidental physical activity are positively associated with cognition and EEG activity in aging 

      Sanchez-Lopez, Javier; Silva-Pereyra, Juan; Fernandez, Thalia; Alatorre-Cruz, Graciela C; Castro Chavira, Susana Angelica; Gonzalez-Lopez, Mauricio; Sanchez-Moguel, Sergio M (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-25)
      High levels of physical activity seem to positively influence health and cognition across the lifespan. Several studies have found that aerobic exercise enhances cognition and likely prevents cognitive decline in the elderly. Nevertheless, the association of incidental physical activity (IPA) with health and cognition during aging has not been studied. Thus, the aim of this study was to evaluate the ...

    • Higher cognitive reserve is associated with better working memory performance and working-memory-related p300 modulation 

      Gutiérrez-Zamora Velasco, Gabriela; Fernández, Thalía; Silva-Pereyra, Juan; Reynoso-Alcántara, Vicenta; Castro Chavira, Susana Angelica (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-01)
      This study aims to examine how two levels of cognitive reserve, as evidenced by reading syntactic skill, modify performance and neural activity in a two-load-level (high vs. low) working memory (WM) task. Two groups of participants with different reading skills, high and low, were obtained from clustering analysis. We collected the P300 event-related potential component during the performance ...

    • One-Year Follow-Up of Healthy Older Adults with Electroencephalographic Risk for Neurocognitive Disorder after Neurofeedback Training 

      Alatorre-Cruz, Graciela C.; Fernández, Thaliá; Castro Chavira, Susana Angelica; González-López, Mauricio; Sánchez-Moguel, Sergio M.; Silva-Pereyra, Juan (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-15)
      Background: In healthy older adults, excess theta activity is an electroencephalographic (EEG) predictor of cognitive impairment. In a previous study, neurofeedback (NFB) treatment reinforcing reductions theta activity resulted in EEG reorganization and cognitive improvement.<p> <p>Objective: To explore the clinical applicability of this NFB treatment, the present study performed a 1-year follow-up ...
