The Muscle-Brain Cross-Talk

Studies have shown that even in people with existing brain disease or damage, increased physical activity and motor skills are associated with better cognitive function. People with sarcopenia, or age-related muscle atrophy, are more likely to suffer cognitive decline. Mounti...

Skeletal muscle is the type of muscle that allows us to move our body around; it is one of the biggest organs in the human body. It is also an endocrine tissue, which means it releases signaling molecules that travel to other parts of your body to tell them to do things. The protein mole...

Further, there is substantial evidence that certain myokines have sex-differentiated neuroprotective properties. For example, the myokine irisin is influenced by estrogen levels, and postmenopausal women are more susceptible to neurological diseases, which suggests that ...

Even moderate exercise can increase metabolism in brain regions important for learning and memory in older adults. And the brain itself has been found to respond to exercise in strikingly physical ways. The hippocampus, a brain structure that plays a major role ...

In young muscle, a small amount of exercise triggers molecular processes that tell the muscle to grow. Muscle fibers sustain damage through strain and stress, and then repair themselves by fusing together and increasing in size and mass. Muscles get stronger by surviving...
