Mindfulness’s attention to the here and now. It’s being fully present in the moment. You are experiencing the present moment and non-judgmental way. The brain model of depression is hypo-connectivity between the neurons in certain parts of the brain that regulate and process your emotions and a hyper connectivity in the default mode network. In this video I discussed what the default mode network is and how it relates to depression. I also discuss how mindfulness changes these connectivity patterns.
Here are the specific structures of that brain that make up the default mode network.
- The posterior cingulate cortex (PCC; areas 23/31),
- Precuneus, and the medial frontal cortex (MFC, including areas 24/10-m/32),
- Bilateral inferior parietal and posterior temporal areas around the temporoparietal junction area.
