Meditation-related activations are modulated by the practices needed to obtain it and by the expertise: an ALE meta-analysis study.

Bottom Line: Different ALE meta-analyses were carried out.The network included clusters bilaterally in the medial gyrus, the left superior parietal lobe, the left insula and the right supramarginal gyrus (SMG).We found that frontal activation was present for short-term, as compared with long-term experience meditators, confirming that experts are better enabled to sustain attentional focus, rather recruiting the right SMG and concentrating on aspects involving disembodiment.

ABSTRACT
The brain network governing meditation has been studied using a variety of meditation practices and techniques practices eliciting different cognitive processes (e.g., silence, attention to own body, sense of joy, mantras, etc.). It is very possible that different practices of meditation are subserved by largely, if not entirely, disparate brain networks. This assumption was tested by conducting an activation likelihood estimation (ALE) meta-analysis of meditation neuroimaging studies, which assessed 150 activation foci from 24 experiments. Different ALE meta-analyses were carried out. One involved the subsets of studies involving meditation induced through exercising focused attention (FA). The network included clusters bilaterally in the medial gyrus, the left superior parietal lobe, the left insula and the right supramarginal gyrus (SMG). A second analysis addressed the studies involving meditation states induced by chanting or by repetition of words or phrases, known as "mantra." This type of practice elicited a cluster of activity in the right SMG, the SMA bilaterally and the left postcentral gyrus. Furthermore, the last analyses addressed the effect of meditation experience (i.e., short- vs. long-term meditators). We found that frontal activation was present for short-term, as compared with long-term experience meditators, confirming that experts are better enabled to sustain attentional focus, rather recruiting the right SMG and concentrating on aspects involving disembodiment.

The brain networks supporting long-term (A) and short-term (B) meditation experience are displayed on a rendered template brain provided by spm5 and on axial slices of the MNI single subject template, with long-term (orange) and short-term (blue) meditation experience related activations overlaid on the same template (C). All activations are significant at p < 0.05 corrected for multiple comparisons using the false discovery rate (FDR). Color bas show ALE value.

Figure 2: The brain networks supporting long-term (A) and short-term (B) meditation experience are displayed on a rendered template brain provided by spm5 and on axial slices of the MNI single subject template, with long-term (orange) and short-term (blue) meditation experience related activations overlaid on the same template (C). All activations are significant at p < 0.05 corrected for multiple comparisons using the false discovery rate (FDR). Color bas show ALE value.

Mentions: Lastly, in further sub-analysis we investigated the effects of meditation experience. The brain network supporting long experience meditation included cluster of activity in the right SMG (cluster 1), the SMA and the paracentral lobule bilaterally (clusters 2 and 4), the middle cingulated cortex and the postcentral gyrus (clusters 5 and 6). Short experience included clusters of activity in the superior medial gyrus and the inferior parietal lobule (clusters 1, 2, and 3, Table 2 and Figure 2). By contrast, the superior parietal lobe was found activated independent of meditation experience. By excluding from the analysis performed on the short-term meditation experience data from studies involving participants with less than 1 year meditation experience, we found the same pattern of results.
