Researchers at the Icahn School of Medicine at Mount Sinai discovered that meditation affects the amygdala and hippocampus. These brain regions regulate emotions and memory. The study, published in PNAS, highlights how meditation could enhance mental health and memory function.
Meditation trains the mind to focus and increase awareness. Prior research links it to improved mental well-being and relief from psychiatric disorders like anxiety and depression. Yet, the exact brain mechanisms behind these benefits remain unclear.
A UNIQUE APPROACH TO BRAIN RESEARCH
Studying deep brain activity is difficult with standard scalp EEG. Researchers overcame this by using data from epilepsy patients with implanted brain electrodes. “It was amazing to see brain wave changes, even in first-time meditators,” said lead author Christina Maher.
TRACKING IMPACT
The study examined eight epilepsy patients with implanted neurostimulation systems. They were novice meditators and followed a five-minute audio-guided session before practicing ten minutes of “loving-kindness” meditation. This method focuses on directing positive thoughts toward oneself and others.
MEDITATION AND BRAIN WAVES
After meditating, participants reported an average deep meditation score of 7.43 out of 10. Neuroscientist Ignacio Saez noted significant changes in beta and gamma brain waves. These waves are linked to mood regulation and cognitive function. It allow individuals to control these waves, offering potential benefits for mental health.
A REAL-WORLD RESEARCH SETTING
Unlike traditional hospital studies, this research took place in a calming, therapeutic environment. This setting helped ensure that participants experienced meditation in a more natural way. The study used advanced neural recording techniques, providing detailed insights into brain activity.
STUDY LIMITATIONS AND FUTURE RESEARCH
The sample size was small, and researchers only analyzed short-term effects. They did not track long-term changes or repeated practice. “This study is a foundation for future research,” said Dr. Saez. Researchers plan to study meditation’s long-term impact on brain activity and mental well-being.
MEDITATION AS A COMPLEMENTARY THERAPY
Meditation is noninvasive, widely accessible, and does not require medical resources. It can complement traditional therapies for those struggling with emotional regulation and memory. However, it should not replace medical treatment.
THE NEXT STEPS IN RESEARCH
The Mount Sinai team will expand their research to explore how long-term meditation impacts mental health. More data could solidify meditation’s role as a powerful tool for emotional and cognitive well-being.
