Paralyzed Man Walks Again After “Nose” Cells Repair Spinal Cord

The spinal cord is responsible for communication between the brain and the central nervous system, which is the command center for our body’s actions. It’s what allows us to pick up a toothbrush and apply some toothpaste when we think, “time to brush our teeth”.

It’s what allows us to roll our eyes when a patient (or doctor) says something idiotic.

The attack left him with a seven millimeter gap in his spinal cord.

There are certain neurotransmitters, primarily serotonin, which tend to be deregulated for people who have clinical depression, also known as Major Depressive Disorder (MDD), but there aren’t many answers as to why these areas of the brain differ in depressed people.

Dr. Turhan Canli, an integrative neuroscience associate professor at Stony Brook University, has stirred up a bit of controversy in the science community after making claims that depression may have less to do with brain chemistry, and more to do with a viral or bacterial infection, the Huffington Post report
