Conductivity cable theory

It should be mentioned, that the incorporation of the intercalated discs in the model completely changes classical relationships obtained from continuous ( Hodgkin-Huxley ) cable theory. For example, the inverse square root relationship between velocity and axial resistance does not hold, and an increase in accompanies slow conduction caused by high disc resistance. These deviations from classical continuous cable theory are further discussed elsewhere (Diaz et al., 1983 Rudy et al., 1983). 

Reeling devices work by dropping a sensor down on a cable and sensing the bed level by optical or conductivity sensors. In theory they are nonfouling and get out of the way of the rakes, but in...
