Norepinephrine sends signals widely throughout the brain that move us into a task motivated stated. A brain regain called the locus coeruleus located in the brain stem is involved in the release of norepinephrine. As we shift to a more passive state, another type of brain cell called astrocytes take over (they get their name from their star shape). Astrocytes cells support neurons in the brain, and are the most abundant glial cells in the brain. A study by Yu Mu et al, 2019 (link below) with Zebra fish shows that Norepinephrine was released when they are moved to actively swim. Meanwhile, astrocyte activity increased when the fish moved to a passive state. When workers get tired, just like the Zebra fish who felt they were not getting anywhere with their swimming, a passive state sets in the brain. To overcome this passive state and increase Norepinephrine release into the brain, take a break or change up work pattern to increase productivity again. Other ways to increase task-engaged brain activity include getting early light exposure and exercising. Stay safe and healthy out there!
