Modulation of Cortical Brain Activity During Attentional Control
Sponsor: National Council of Scientific and Technical Research, Argentina
Summary
The goal of this study is to determine whether an open-loop sham neurofeedback system can effectively modulate EEG alpha rhythms, which are associated with attentional control. The main questions it aims to answer are: Does positive sham neurofeedback lead to a decrease in relative EEG alpha power compared to a control condition without feedback? Researchers will compare the effects of positive and negative sham-neurofeedback conditions to a control condition without feedback to assess the system's impact on alpha rhythm modulation. Participants will: Experience three conditions (positive sham-neurofeedback, negative sham-neurofeedback, and no feedback) within a virtual reality environment. Undergo EEG recordings to measure changes in alpha power as a marker of attentional resource allocation. Provide written informed consent and complete the study following ethical guidelines. This study seeks to explore the potential of open-loop feedback systems to enhance attentional control by modulating alpha rhythm.

Conditions
Interventions
Positive sham neurofeedback
Participants receive simulated positive reinforcement feedback designed to mimic successful modulation of EEG alpha rhythms, despite the feedback not being directly based on their actual neural activity. This condition aims to create the perception of improved attentional control.
Negative sham neurofeedback
Participants receive simulated negative reinforcement feedback that mimics unsuccessful modulation of EEG alpha rhythms, regardless of their actual neural activity. This condition is intended to simulate reduced attentional control.
Control
Participants perform the same attentional task but without receiving any feedback. This condition serves as a baseline to evaluate the effects of the sham neurofeedback interventions on EEG alpha rhythm modulation.
