Such expression is significantly increased following sciatic nerve injury or dorsal root injury, particularly in astrocytes surrounding dorsal funiculus containing the central processes of the injured primary sensory neurons. The mobile device may also include a transceiver that receives information from the server relating to the network connection. A regression analysis may also be performed in order to extrapolate new data from previously received known-good signal segments. The apparatus includes a server component, system client, a mobile client, and multiple application programming interface modules configured to manage information flow and correspond with external systems as needed.
