Spinal Cord Injury: Let’s Clear the Air(ways)

The spinal cord is the information processing highway in animals (including humans) that have a backbone.

About 17,000 people in the U.S. … Continue reading Spinal Cord Injury: Let’s Clear the Air(ways)

What Animals Can Teach Humans about Muscle Maintenance

We all know the saying “use it or lose it.” Your muscles and nerves are no exception. When people are not active, whether it’s because of bed rest, spinal cord and nerve injury, or other reasons, two big problems arise.

The Brain in Your Gut

Did you know your gut has a brain of its own? It’s called the enteric nervous system. The brain in your gut is embedded in the wall of the digestive tract. Together with your “big brain,” the enteric nervous system helps control gastrointestinal function, including the mixing and grinding of food in the stomach and … Continue reading The Brain in Your Gut

How Your Brain Decides to Keep Your New Year’s Resolutions (or Not)

  The start of a new year can feel like a fresh slate or an unwritten book. It’s a chance for many of us to resolve to do things better (eating, exercising) or to stop doing certain things altogether (smoking). But most people don’t succeed in sticking to their resolutions in the long term, and … Continue reading How Your Brain Decides to Keep Your New Year’s Resolutions (or Not)

Your Immune System Makes You Mentally Tough
