What is the Default Mode Network?

The Default Mode Network (DMN) is a set of brain regions that are typically active when a person is not focused on the external world but engaged in introspective activities such as daydreaming, recalling memories, envisioning the future, or thinking about others' perspectives. The DMN is particularly active during rest or when someone is not engaged in a specific task.

Dr. Andrew Huberman explains that the DMN comprises several brain areas that generate a state of mind wandering, allowing thoughts to drift from the past to the future. This network becomes less active when attention shifts to specific tasks or external stimuli, such as during focused conversations or activities that require direct attention[1].

In the context of creativity, the DMN is engaged during spontaneous imagination, such as when you close your eyes and let thoughts and images come to mind without any external sensory input. It is crucial for generating new ideas and connections internally[2]. Additionally, the DMN plays a significant role in self-referential thoughts and processes, forming a critical part of how individuals construct a sense of self and navigate social interactions[3].
