Have you ever felt so tired and unable to think after a long day of work or study? That feeling and wanting to go home for a good nap isn’t just in your head. A study published last Thursday (11/8) in the scientific journal Current Biology concluded that mental fatigue generates significant changes in brain metabolism. Member fatigue is characterized by greater difficulty completing tasks or maintaining focus on activities.
The survey included 40 participants, 24 of whom underwent a six-hour work routine with only two ten-minute periods. The other 16 were exposed to a simpler task for the same amount of time. Scientists noticed an increase in glutamate levels in the brains of those who worked harder.
Glutamate is an excitatory neurotransmitter that controls the strength of brain signals and regulates their distribution to neurons. The substance has also been linked to nerve cell death. Despite being a key ingredient in fighting diseases like Alzheimer’s, glutamate can disrupt brain function when it’s in excess.
The more mentally fatigued volunteers were more likely to choose tasks that required less effort and less financial reward. Participants who put in less effort chose jobs that generated more financial recognition in the long run.
Scientists believe that the brain is trying to protect itself from an overload of the neurotransmitter by making cognitive tasks difficult. According to the researchers, a moment of rest may be enough to balance the levels of the molecule in the brain, as well as a good night’s sleep – one of the moments known to clean the brain is known to sleep.
The study is important because it establishes the relationship between mental fatigue and changes in brain metabolism. To arrive at the results, the scientists used a technique called magnetic resonance spectroscopy to measure glutamate levels in the lateral prefrontal cortex, a part of the organ directly associated with working memory.
Now, researchers plan to develop studies aimed at healing people suffering from mental fatigue. It’s already known that rest helps balance glutamate levels, but they also want to understand exactly how the process happens and how much rest will help the brain clear it.
