1. A method for preferentially stimulating neural somas with respect to neural axons located near the somas but not integral with the neural somas, in a region of neural tissue comprising: positioning a stimulating electrode in the vicinity of the region of neural tissue and, applying a positive electrical pulse to the region of neural tissue including one or more neural somas to be stimulated and neural axons to lower a stimulation thresholds of the neural somas with respect to thresholds of the non-integral neural axons, whereby the neural somas of the neural tissue are preferentially stimulated by the positive electrical pulse over the neural axons not integral with the neural somas to be stimulated.
