  cable properties
With largerneurons, it becomes difficult to maintain conduction times over longer axons andelectrical cable properties over longer dendrites.
      
In order to assess the effects of [KK]o on the passive membrane properties of neostriatal neurons, the cable properties of these cells were determined at two extracellular potassium concentrations (6.25 and 3.0 mM).
      
The effect of tetraethylammonium (TEA) on cable properties was also studied at 6.25 [KK]o.
      
The results suggest that changes in [KK]o, within the physiological range, markedly affect the cable properties of neostriatal neurons, possibly modifying subthreshold, voltage-dependent KK-conductances.

In the analysis of transients in mine electrical power systems, the modeling of system components can be conveniently used for digital simulation of electrical transi ents on mine underground power systems. The Paper deals with the modeling of the raining cable. The result can be used to a cable-oriented study and also to a sys tem—oriented transient study. A cable—oriented model represents all of the conductors and their mutual effects, while a system—oriented model is a simplified version of the first. The cable—oriented model is useful in detennining stray ground currents caused by system unbalance, ground monitor damage caused by large spikes in ground current, and other ground related phenomena. The system—oriented model is used for linking the machinery when the transients being measured are machine transients. 4figs., 3refs.
