Meditation and Yoga Reshape Our Brains

(Last Updated On: August 20, 2016)

Neuroscientist Sara Lazar’s brain scans show that yoga and meditation actually change the size of key regions of our brain, improving  memory and making us more empathetic, compassionate, and resilient under stress.

In the documentary, The Connection, Sara Lazar reports the following findings:

 We found differences in brain volume after eight weeks in five different regions in the brains of the two groups. In the group that learned meditation, we found thickening in four regions:

1. The primary difference, we found in the posterior cingulate, which is involved in mind wandering, and self relevance.

2. The left hippocampus, which assists in learning, cognition, memory and emotional regulation.

3.  The temporo parietal junction, or TPJ, which is associated with perspective taking, empathy and compassion.

4. An area of the brain stem called the Pons, where a lot of regulatory neurotransmitters are produced. The amygdala, the fight or flight part of the brain which is important for anxiety, fear and stress in general. That area got smaller in the group that went through the mindfulness-based stress reduction program. The change in the amygdala was also correlated to a reduction in stress levels.
