Excellent for bipolar stimulation studies where the current injection needs to be confined to a small localized part of the neural tissue.
Stereotrodes have also been used for enhanced isolation of single neural elements by simultaneous recordings of multiple units on two closely spaced microelectrodes. The tip spacing is typically equal to the diameter of the electrode shaft, however, they can be specified to greater separations in most instances.
