As a woman's levels of progesterone and oestrogen vary, so does the connectivity between two brain networks: the default mode network
and the salience network.
These interconnected parts formed a system referred to as the 'default mode network
(10) demonstrated that abnormality existed in the default mode network
of aMCI patients.
One function of the salience network, he said, is to regulate switching between the default mode network
(DMN)--an interoceptive network --and the central executive network, usually active in exteroceptive tasks.
Celebrity psychologist and contributing expert Jo Hemmings says: "During auto-pilot activities like being in the shower, the pre-frontal cortex in the brain -- which controls decision making and focused goals -- is relaxed and the brain's default mode network
comes into play, giving us clarity and creativity."
The most commonly used is the default mode network
which involves the medial prefrontal cortex and the posterior cingulate cortex and lateral parietal cortex.
Huang et al . reported that increased global functional connectivity density (gFCD) within the default mode network
might be an important neural mechanism of mECT in schizophrenia.
People who had lower levels of mindfulness displayed greater activation of this important region, which is part of the brain's default mode network
. The default mode network
disengages when you're engaged in a task such as reading or writing.
The participants had a mean FMness score of 13.2 (range, 1 to 29) and, using whole-brain analyses, the researchers found a single significant positive correlation between default mode network
connectivity to the left mid/posterior insula and FMness.
The results indicated that the gFCD of the dorsomedial prefrontal cortex, the ventromedial prefrontal cortex, and the left anterior precuneus increased only in the antipsychotics +MECT treatment group, suggesting MECT might play a therapeutic role by enhancing the functional connectivity strength in the default mode network
Default mode network
located on anatomical regions including anterior and posterior midline structures, and parietal and medial temporal areas shows alterations in the presymptomatic period before the structural changes in AD (5).
