Default mode network functional connectivity as a transdiagnostic biomarker of cognitive function.
Biol Psychiatry Cogn Neurosci Neuroimaging
January 2025
The default mode network (DMN) is intricately linked with processes such as self-referential thinking, episodic memory recall, goal-directed cognition, self-projection, and theory of mind. Over recent years, there has been a surge in examining its functional connectivity, particularly its relationship with frontoparietal networks (FPN) involved in top-down attention, executive function, and cognitive control. The fluidity in switching between these internal and external modes of processing-highlighted by anti-correlated functional connectivity-has been proposed as an indicator of cognitive health.

- Involuntary thinking happens when thoughts pop into your head without you wanting them to, like random memories or worries.
- The study looked at different types of these unexpected thoughts to understand how they feel different from other involuntary thoughts.
- Researchers found that unexpected thoughts are usually surprising and give new ideas, while other types of involuntary thoughts are often more connected to what you're already thinking about.
Prefrontal contributions to the stability and variability of thought and conscious experience.

Article Synopsis
- The prefrontal cortex is an important part of the brain that helps with many activities like thinking about goals and daydreaming.
- Different parts of the prefrontal cortex work with other brain networks in special ways.
- Two ideas about how our thoughts work, called DFT and REBUS, can help us understand how different parts of the prefrontal cortex affect how stable or changing our thoughts and experiences can be.
Out of the blue: understanding abrupt and wayward transitions in thought using probability and predictive processing.
Philos Trans R Soc Lond B Biol Sci
February 2021
Thoughts that appear to come to us 'out of the blue' or 'out of nowhere' are a familiar aspect of mental experience. Such thoughts tend to elicit feelings of surprise and spontaneity. Although we are beginning to understand the neural processes that underlie the arising of such thoughts, little is known about what accounts for their peculiar phenomenology.
