EPFL scientists have developed a non-invasive technique for unraveling the complex dynamics generated by spinal cord circuits to unprecedented detail, a first in functional magnetic resonance imaging that may one day help diagnose spinal cord dysfunction or injury.
The spinal cord roughly looks like a long tube, with a diameter of only 1.5 cm, and yet this crucial part of the nervous system is essential for controlling how our arms and legs move, for giving us our sense of touch as well as a notion of where our bodies are in space.
Any damage to the nervous system can be permanent and devastating. One of the issues is that neurons aren’t really that great at regenerating. The axons and dendrites that actually conducts the majority of the signal are only thin protrusions from the main neuron cell body. In many cases, these neurons link with each other in very complex patterns. It could be argued that efforts to repair spinal cord injuries are almost simple in comparison to other nervous system damage.
