EEG Alpha Rhythm Modulation Using Sham Neurofeedback During Attentional Control in a Virtual Reality Environment
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.
Inclusion: Adults aged between 18 and 60 years; Normal or corrected vision; Ability to provide written informed consent.
Exclusion: Diagnosed with photosensitive epilepsy; Significant hearing loss or diagnosed hearing impairment; Current psychiatric illness or disorder; History of migraines or chronic headaches; History of substance or alcohol abuse; Currently pregnant; Discomfort with using a virtual reality headset, assessed during a pilot session.
