The brain’s default network: Anatomy, function, and relevance to disease. Plus three other important networks in your brain.

This is a very good and easy to understand article about the Default Mode Network (DMN) in our brain.

It is in the DMN the process of scene construction takes place, a kind of mental simulation of reality rather similar to what William James used to call the “stream of consciousness”.

Also read this article: . About how creativity is implemented in the brain.

In that article you can read about another default network in your brain: the Default Imagination Network (DIN).

The DIN is involved in constructing dynamic mental simulations based primarily on personal past experiences. It provides us with alternative perspectives and scenarios to the present “view”. The DIN is, in turn, dependent on how we are primed (i.e. what we are taught/conditioned to believe and/or how we interpret what we see, hear, experience and so on).

The DIN cooperates with two other neural networks: 1) the Executive Attention Network (EAN), and 2) the Salience Network (SN).

The EAN is all about attention vs. inattention. It helps us to focus and concentrate – or stop focusing/concentrating.

The SN tags the events (both external and/or internal) that we experience (become aware of), either consciously or unconsciously, and tells us how relevant (= salient) any information is with regard to solving the task at hand.

All three networks can, of course, be influenced by how our brains are primed. That’s why a believer in demons or angels interprets his experience as evidence of existence of spiritual other-worldly religious beings, whereas the UFO believer is convinced he has had an encounter with aliens.

  1. Two more articles that are relevant here and therefore deserve mentioning are:
