Recent evidence suggests:
myelin lipids may act as glial energy reserves when glucose is lacking, a hypothesis yet to be solidly proven.
Hereby, we examined the effects of running a marathon on the myelin content by MRI.
Our findings:
marathon runners undergo widespread robust myelin decrease at completion of the effort.
This reduction involves white & gray matter, it includes
- primary motor & sensory cortical areas & pathways,
- the entire corpus callosum & internal capsule.
Myelin levels partially recover within 2 weeks after the marathon.
These results reveal:
myelin use & replenishment is an unprecedented form of metabolic plasticity, aimed to maintain brain function during extreme conditions.
