Have you already given up on a new year’s resolution? Do you think you could handle an 8-week plan to rebuild your brain?

Mediation and mindfulness training has been proven again and again to not only make people feel better but more recently shown to make actual changes in your brain.

An eight-week mindfulness meditation program appears to make measurable changes in brain regions associated with memory, sense of self, empathy, and stress.

A study conducted by a Harvard affiliated team out of Massachusetts General Hospital (MGH) shows some tangible effects of meditation on human brain structure.

Using MRI scans, they found “massive changes” in brain gray matter. The participants didn’t just “feel better” but  showed changes in brain structure that create the associated sustained boosts in positive and relaxed feelings. On of those changes is a thickening of the cerebral cortex. That is the area responsible for attention and emotional integration.

How long did they meditate? It’s not the 5 or 10 minute break you sometimes read about, but it’s also not hours or a weekend of meditation. An average of 27 minutes of a daily practice of mindfulness exercises stimulated a significant boost in gray matter density.

That density is focused on the hippocampus which is associated with self-awareness, compassion, and introspection. There was also decreased gray matter density in the amygdala. That might sound like a bad thing, unless you know that the amygdala is the area of the brain known to be instrumental in regulating anxiety and stress responses.

The control group of non-meditators did not have any changes occur in either region of the brain, so the simple passage of time was not a factor.

The one story that gets repeated over and over in the past 50 years is that there is far more brain plasticity – the changeable (or “plastic”) ability of the brain to change -into adulthood than was previously believed. You can teach old dogs new tricks.
