Even in the resting state-certain regions of the brain are active. One of the functions of the active state of the default mode network is to maintain vigilance to protect oneself from danger. The activation of the brain is considered in the asleep condition of the brain which can be explained by the sentinel hypothesis.
The involvement of the peripheral vision increases the active task, as the resting state diffusely monitors our broad visual field.
In a resting stage, the area of the visual field is increased compared to a focussed state in which the visual field is on a target. Interoception of the organs such as the beating of the heart, imagination, autobiographical memory that involves collective analysis of the visual information, recollection of episodes in the past, and understanding of one-self. Damage to the default mode network affects the thinking, and interpretation of the person in relation to the above activities.
The medial prefrontal cortex, posterior cingulate cortex, posterior parietal cortex, hippocampus, and lateral temporal cortex are active even during the resting state.
