Understanding the impact of human actions on the environment
We’ve often thought about muscle as a thing that exists separately from intellect—and perhaps that is even oppositional to it, one taking resources from the other. The truth is, our brains and muscles are in constant conversation with each other, sending electrochemical signals back and forth. In a very tangible way, our lifelong brain health depends on keeping our muscles moving.

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 ...

Myokines are released into the bloodstream when our muscles contract, create new cells, or perform other metabolic activities. When they arrive at the brain, they regulate physiological and metabolic responses there, too. As a result, myokines have the ability to affect cognition, mood, a...

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...
