Title: Neural correlates of attentional expertise in long-term meditation practitioners

Summary: With the use of fMRI it was found that people with an average of 19.000 hours of meditation experience had greater activation of brain regions associated with sustained attention than novice meditators. However it appears that experienced meditators with an average of 44,000 hours meditation had less activation of the same regions (inverted u-shaped curve distribution). When compared to novices, experienced meditators appear to have less brain activation in regions related to discursive thoughts but greater activation in response inhibition regions.

Title: Effects of Mindful-attention and Compassion Meditation Training on Amygdala Response to Emotional Stimuli in an Ordinary, Non-meditative State

Summary: There is a long standing association between the amygdala and emotional processing. Previous research has indicated that in a meditative state amygdala response to emotional stimuli could be reduced. However this investigation points to the possibility that the effect of meditation training on emotional processing may exert an influence beyond the meditative-state. Participants were given training in either Mindful Attention Training (MAT) or Cognitively-Based Compassion Training (CBCT).

Title: Regulation of the Neural Circuitry of Emotion by Compassion Meditation: Effects of Meditative Expertise

Summary: Functional magnetic resonance imaging (fMRI) investigation of the insula and anterior cingulate cortices in empathic response during loving-kindness, compassionate meditation. The contrast between rest and meditation states indicated increased activation in amygdala, right temporo-parietal junction (TPJ), and right posterior superior temporal sulcus (pSTS). The findings when taken in their entirety suggests the cultivation of positive emotional states through meditation creates changes to the activation of circuitries  linked to empathy and theory of mind in response to emotional stimuli.

Title: Open Hearts Build Lives: Positive Emotions, Induced Through Loving-Kindness Meditation, Build Consequential Personal Resources

Summary: Does meditation practice produce a cumulative effect? Is there a relationship between meditation and positive emotions, which, in turn produce increased personal resources connected to life satisfaction and reduced depressive symptoms.

Title: Loving-Kindness Meditation for Chronic Low Back Pain

Summary: A pilot study on the effects of an eight week loving-kindness meditation program for patients suffering with chronic low back pain. Participants measured for pain, anger, and psychological distress. Analyses of data suggested a relationship between loving-kindness meditation and  lower pain on the day of meditation and a lower experience of anger the following day.

Title: Loving-kindness meditation increases social connectedness

Summary: This research examines the relationship between social connectedness and meditation. It discusses whether social connectedness could be created toward strangers in a controlled laboratory context. The findings imply that even brief exposure to loving kindness meditation (LKM) may offer some relief from the experience from social isolation.
