Researchers identify brain regions linked to mental exhaustion

New research published in the Journal of Neuroscience has identified two specific brain regions that work together to signal mental exhaustion. Using functional magnetic resonance imaging (fMRI), scientists observed increased activity in these areas during experiments where healthy volunteers performed memory tasks.

The study, funded by the U.S. National Institutes of Health (NIH), suggests that these brain regions may play a role in regulating the decision to either continue exerting mental effort or to give up. Dr. Vikram Chib of Johns Hopkins University noted that while the biology of physical tasks is well understood, more research is needed regarding how mental fatigue develops and manifests in the brain.

Clinical implications of this discovery include the potential for doctors to more accurately assess and treat individuals suffering from severe mental exhaustion, including those with depression and post-traumatic stress disorder (PTSD).
