[IMPACT OF INDIVIDUAL PERSONALITY FEATURES ON ABILITY TO VOLUNTARY REGULATION OF EXPRESSION EEG ALPHA AND BETA...

Area of Science:

• Neuroscience
• Cognitive Psychology
• Psychophysiology

Context:

• Investigating voluntary control of brainwave frequencies.
• Utilizing biofeedback for neuroregulation.
• Examining electroencephalography (EEG) patterns in specific brain regions.

Purpose:

• To assess the feasibility of voluntary control over alpha and beta-2 frequency bands.
• To determine the influence of personality traits on the effectiveness of brainwave control.
• To compare the ease of controlling different frequency bands in distinct cortical areas.

Summary:

• Seventeen volunteers underwent biofeedback training to modulate alpha and beta-2 brainwave frequencies in parietal and frontal cortical areas.
• Results indicated that decreasing beta-2 frequency expression in the frontal cortex was easier than reducing alpha frequency power in the parietal cortex.
• Individual personality features, including extraversion, psychoticism, neuroticism, and anxiety levels, significantly impacted the effectiveness of voluntary brain activity control.

Impact:

• Provides insights into the neural mechanisms of voluntary brainwave regulation.
• Highlights the role of personality in cognitive control and neurofeedback efficacy.
• Suggests potential applications for targeted neurofeedback interventions based on personality profiles.
