Neurology – Spinal Cord Introduction
American football has a proud place in professional and collegiate sports, not to mention in hometown culture. Lately, the focus in football has been on concussions and chronic traumatic encephalopathy, a degenerative brain disease linked to damage caused by repetitive hits to the head. Spinal cord injuries are also a serious problem, as one of us (R.L.) learned the hard way with an injury that ended his career with the Seattle Seahawks.
That’s why we have teamed up to help create a comprehensive three-dimensional atlas of the human spinal cord, a missing piece of the puzzle that will help improve the understanding and treatment of these difficult injuries. Football, of course, isn’t the only cause of spinal cord injuries.
Snakes owe their long and slithery bodies to “junk DNA,” large chunks of the reptile’s genome that scientists once thought to be useless. The gene called Oct4 may eventually help treat people with spinal injuries.
Oct4 is responsible for regulating stem cells and affects the growth of the trunk in the middle part of a vertebrate’s body.
Study researcher Rita Aires, from Portugal’s Instituto Gulbenkian de Ciencia (IGC), explained that genes involved in the formation of the trunk have to stop their activities so that the genes that are involved in tail formation can begin their work.
London: Humans and monkeys exhibit greater motor recovery than rats after similar spinal cord injury, new research shows.Spontaneous improvement occurs during the first six months after a spinal cord injury, allowing a hemiplegic patient to recover partial motor control.
The neuronal mechanisms underlying this extensive recovery in primates are nearly absent in laboratory rats, researchers said. “Research on rats is essential for developing regenerative therapies, but rodents show fundamental differences from primates in terms of neuronal reorganisation and functional recovery,” say researchers.

Newswise — A study led by researchers in the Department of Neurosciences at the University of California, San Diego School of Medicine shows unexpected and extensive natural recovery after spinal cord injury in primates. The findings, to be published November 14 in the advance online edition of Nature Neuroscience, may one day lead to the development of new treatments for patients with spinal cord injuries.
While regeneration after severe brain and spinal cord injury is limited, milder injuries are often followed by good functional recovery.
