The neuroscience of emotions and thoughts during meditation
This scientific paper has just come out studying the effects of meditation on the brain. The interesting thing is that when the meditators performed a non-focussed meditation, where they allowed their mind to wander, their emotional brain areas got activated. In other words, when they stopped attempting to direct thought, emotions were more likely to flow. This fits with how if we stop being so mind dominant, we will become more emotional and our soul will be more fully expressed: http://journal.frontiersin.org/article/10.3389/fnhum.2014.00086/full
Here is the abstract of the paper:
Nondirective meditation techniques are practiced with a relaxed focus of attention that permits spontaneously occurring thoughts, images, sensations, memories, and emotions to emerge and pass freely, without any expectation that mind wandering should abate. These techniques are thought to facilitate mental processing of emotional experiences, thereby contributing to wellness and stress management.
The present study assessed brain activity by functional magnetic resonance imaging (fMRI) in 14 experienced practitioners of Acem meditation in two experimental conditions.
In the first, nondirective meditation was compared to rest. Significantly increased activity was detected in areas associated with attention, mind wandering, retrieval of episodic memories, and emotional processing.
In the second condition, participants carried out concentrative practicing of the same meditation technique, actively trying to avoid mind wandering. The contrast nondirective meditation > concentrative practicing was characterized by higher activity in the right medial temporal lobe (parahippocampal gyrus and amygdala).
In conclusion, the present results support the notion that nondirective meditation, which permits mind wandering, involves more extensive activation of brain areas associated with episodic memories and emotional processing, than during concentrative practicing or regular rest.
