Functional Connectivity of Prefrontal Cortex in Various Meditation Techniques - A Mini-Review.

Area of Science:

• Neuroscience
• Cognitive Psychology
• Psychiatry

Background:

• Meditation is a practice involving concentration and relaxation, aiming for self-consciousness.
• Diverse meditation types exist, including Mindfulness, compassion, transcendental, and focused attention.
• Meditation is increasingly recognized for its potential to modulate brain function and structure.

Purpose of the Study:

• To review neuroimaging studies on the functional connectivity of the prefrontal cortex (PFC) across various meditation practices.
• To elucidate the relationship between meditation and PFC functional connectivity in healthy individuals.
• To explore the implications of altered PFC connectivity in neurological and psychosocial disorders.

Main Methods:

• Systematic review of neuroimaging interventions, primarily fMRI studies.
• Comparison of functional connectivity in meditators versus non-meditators.
• Analysis of studies focusing on the prefrontal cortex and its connections during meditation.

Main Results:

• Meditation is associated with increased neural function, default mode network activity, gray matter volume, and functional coupling in PFC regions.
• Enhanced PFC functional connectivity correlates with improved attention, memory, cognitive control, and emotion regulation.
• Meditation practice leads to reduced symptoms of anxiety, depression, stress, and hyperarousal.

Conclusions:

• Meditation positively influences the functional connectivity of the prefrontal cortex.
• Altered PFC connectivity is implicated in various neurological and psychosocial disorders.
• Meditation may hold therapeutic potential for treating disorders characterized by aberrant prefrontal connectivity.
