I would recommend to take a look at the website of [Meditation and Mindfulness Research Group][1] at Liverpool John Moores University. They not only present the results of various studies but also explain those in simpler, not-too-scientific terms. In their research blog they discuss [neuroplasticity and meditation][2], [neural mechanisms of attentional control in mindfulness meditation][3] or [Cognition and Emotion in Meditation][4], to name a few.

[This article][5] also seems to nicely sum up the effects of meditation with links to the peer-reviewed articles. The author groups the effects of meditation in the following categories:

- It boosts your health
- It boosts your happiness
- It boosts your social life
- It boosts your self-control
- It changes your brain (for better)
- It improves your productivity
- It makes you wiser
