How Meditation Changes the Brain. The Brain (Before and After) Meditation

Can Neuroscience Tell Us How Many Hours of Meditation It Takes to Change the Brain?

How meditation changes the brain is a novel topic of interest for neuroscientists, researchers, health providers, and meditators globally. Neuroimaging shows us the brain before and after meditation. It also shows the areas of the brain that activate and change during and after meditation. Research can even tell us how many hours of meditation are needed to change the brain.

Discover what neuroscience studies have revealed about meditation and how it can benefit the mind and body.

As we know, meditation has been practised worldwide throughout human history. The current number of meditators is ever-increasing. Current estimates sit between 200 and 500 million people meditating worldwide(*1).

Thanks to recent technological advances, science is starting to find ways to explain how and why meditation works for stress, blood pressure, the immune system, mental health, pain, concentration, emotional regulation and resilience and fatigue management, to name a few.

For 15 years, Dr David Vago has been a leader in neuroscience and mind-body research(*2). In a recent article, Vago provides findings from neuroimaging research on meditation. We provide a snapshot of some of the most exciting discoveries from the article below.

It is interesting to note that even Vago, after having done such extensive research, acknowledges that neuroscience does not yet have all the required tools to comprehensively measure the scope of the impact of meditation(*3).

In saying that, what Vago and other researchers have been able to quantify is eye-opening and affirms what we know, through our lived experience as meditators.

Read on to discover what neuroscience can tell us about meditation and how it changes the brain.

EEG – Electrophysiology and Meditation

There are approximately 60 years of electrophysiology (EEG) (study of electrical activity in the brain) research on meditation(*3). Meditators of varying disciplines have participated in studies to help us all better understand the science behind meditation. While the strongest results were seen in experienced meditators, even new practitioners showed positive results. Common findings in EEG studies of meditators include:

• Power/amplitude (40–70 µv)(*3).
• Increased slow alpha (8-9Hz) (*3).
• Occasional theta trains (5–7 Hz) in brain areas including the medial frontal gyrus and anterior cingulate(*3).
• Lower delta waves (2–4 Hz)(*3).
• Lower beta waves (12–14 Hz)(*3).
• Clear gamma-band activity(*3).

For those who are not neuroscientists, what does this all mean?

A specific set of changes in brain activity of meditators that correlate to physiological changes in the body were found(*3). Notably, these included the combination of alertness and a hypometabolic state (similar to a bear hibernating in winter). Those who enter hypometabolic states have a greater tolerance and thus survive longer when exposed to stressors(*5). Some studies have also demonstrated that the hypometabolic state can reduce the number of hours of sleep required because it naturally allows the body to complete some of the restorative functions that only happen during sleep(*3,6).

Achieving a hypometabolic state (or deep rest state) is achievable for everyone through guided meditation. Many of our students feel refreshed, lighter and significantly more relaxed after just one meditation class.

Vago(*3) also reviewed 20 years of fMRI meditation research, multiple findings were discovered. Of note, it was found that the brain not only changed in a range of areas during meditation but, for many practitioners, these changes became long-term whether they were in a meditative state or not. This finding confirms that structural changes in the brain as a direct result of meditation can happen.

What Parts of the Brain Have Been Proven to Benefit From Meditation?

In the fMRI meditation studies Vago(*3) reviewed, multiple brain regions and networks related to emotion and cognition were commonly positively impacted. These areas regulate the ability to evaluate and express oneself, self-regulation, self-awareness, self-integration, and self-transcendence(*3).

Structural changes such as cortical thinning (connected to Alzheimer’s Disease) were also observed to be different between meditators and non-meditators. Cortical thickness naturally thins with age however, not so much in meditators(*3).

In one study, the cortical thickness of meditators and non-meditators aged 40 to 50 years showed that meditators had thicker cortical linings – thus greater neuroprotective qualities(*3). Further investigation saw that the 40 to 50-year-old meditators had a similar cortical thickness to their 20 to 30-year-old meditation peers(*3).

Meditation is a Gold Class Mind-Body-Interaction

Thanks to the culmination of decades of research, meditation is now recognised as a ‘gold class’ mind-body interaction(*3). Gold class mind-body interactions positively impact well-being and health (such as relaxation, nutrition and group-based psycho-education)(*3).

While there is still much more research to be done to fully understand all of the science behind meditation, we are thrilled that science is advancing enough to complete such important research.

Across all studies, changes were seen in the brain of novices and highly experienced meditation practitioners.
