Mindfulness meditation is known to improve attention, and neuroscience appears to be a field that can elucidate how mindfulness meditation achieves such an outcome. However, studies on mindfulness meditation have been criticized for a low methodological quality. Thus the current paper aimed to provide a literature review on the neural basis of the effects of mindfulness meditation on attention. Additionally, there was a critical examination of this research to evaluate factors that might compromise the validity of the research. The scope of the thesis was limited to studies on healthy adults using fMRI and on studies that incorporate the generally accepted elements of mindfulness meditation. A total of 17 cross-sectional and two longitudinal studies were reviewed with 510 participants in all. The main result of this literature review were that changes were observed in the mPFC. Furthermore, activation was seen in the insula, prefrontal areas and the ACC. Some of the interpretations of the selected studies were in conflict with each other. This can perhaps be explained by differences in neural activation depending on how experienced the subjects are in mindfulness meditation practices. Some prevalent methodological issues with the studies were small sample sizes, cross-sectional design, and poor or unclear instructions (e.g., not describing the instructions or the mantra employed). There were also more general problems regarding functional neuroimaging. These included movement artefacts and cardiovascular effects. However, based on the 19 studies reviewed in this paper there is tentative evidence for the beneficial effects of mindfulness meditation on attention.
