Here are a few interesting facts about how meditation impacts the brain:

1. When we meditate, it decreases the beta waves in our brain which means that the brain stops processing information actively. This helps improve concentration and reduces anxiety and stress.

2. Neuroplasticity is the ability of the brain to strengthen itself. Meditation has been shown to improve neuroplasticity considerably.

3. Studies have shown that meditation can increase the grey matter in the brain's frontal parts and hippocampus. It is this grey matter that is responsible for increasing emotional stability and positive thinking.
