Neurophysiological Correlates of Meditative States: A Comprehensive Analysis of Brainwave Modulation, Neuroplasticity, and the Efficacy of Simplified Kundalini Yoga (SKY)

Abstract

The scientific investigation into the nature of human consciousness has increasingly pivoted from purely philosophical inquiry toward measurable neurophysiological paradigms. Central to this transition is the study of meditation, a diverse array of mental training practices that significantly alter brain architecture and electrical activity. This research report provides an exhaustive analysis of the relationship between meditative practices and brainwave modulation, with a specific focus on the Simplified Kundalini Yoga (SKY) system developed by Vethathiri Maharishi. By synthesizing data from electroencephalography (EEG), structural Magnetic Resonance Imaging (MRI), and biochemical markers such as serum cortisol, this analysis maps the transition of the meditative mind across a spectrum of neural oscillations—from the alertness of Beta to the profound stillness of Delta and the integrative coherence of Gamma. The study explores the systemic methodology of SKY Yoga, including Kaya Kalpa and Nine Centre Meditation, and evaluates their clinical efficacy in managing stress, ADHD, and hormonal imbalances. Furthermore, the report examines the mechanisms of neuroplasticity, particularly within the prefrontal cortex, hippocampus, and default mode network, illustrating how sustained practice facilitates long-term structural changes. Finally, the report integrates these findings into the Global Workspace Theory of consciousness, proposing that meditation serves as a systematic method for navigating the layers of human awareness and optimizing the brain’s integrative functions for both individual and global well-being.
