Do you ever catch yourself lost in thought or stuck in endless scrolling? That is your brain’s Default Mode Network (DMN) at work. As its name suggests, this neural network is often referred to as our “default” mode, and is closely associated with mind wandering and introspection. The DMN also plays a crucial role in maintaining the “resting state” of the brain, allowing for memory consolidation and recharging.
However, it is very easy to slip into the DMN, especially with the constant barrage of notifications bombarding our senses. Its pervasiveness makes it very challenging for us to stay focused on tasks at hand. Over time, this can lead to procrastination and reduced productivity.
On the other hand, we have another functional neural network known as the Task Positive Network (TPN). Think of the TPN as the driver that keeps your mental energy on track towards productivity. Unlike the DMN, which is focused on internal reflection, the TPN is associated with task execution, goal-directed behaviors, external attention, and active engagement.
The next time you feel yourself slipping into the wandering state of the DMN, remember to activate your TPN. Achieving a balance between the DMN and TPN is essential to optimizing cognitive function. The TPN keeps us grounded, and helps us to effectively tackle necessary tasks. If we can find a way to activate the TPN when necessary, we can achieve a harmonious balance between internal reflection and external engagement.
