English term or phrase: electrode contact
Each of the two interleaving programs can specify the active electrode contact(s), pulse width and pulse amplitude. The frequency for each program must be the same and it is limited by the device up to 125 Hz. One or both electrodes can be interleaved, but no more than two programs can be used for each electrode.
... Double monopolar setting at the amplitude and pulse width necessary to control tremor could not be tolerated due to diplopia. Interleaving allowed a dorsal contact to be set to higher amplitude and pulse width, while the contact below was set to a tolerable lower amplitude and pulse width. Together, the two contacts provided complete tremor resolution without side effects.

disagree  Natalie: Наличие активного электрода предполагает наличие также пассивного электрода, а такая система применяется, например, при коагуляции, тогда как к DBS вообще не имеет отношения. "Активный электрод оборачивают тонким слоем ваты" - это гениально (в мозгу-то)

  -> на активный подается напряжение, вот и всё, а подразумевать? лгбт etc для чІВо?

Reference: DBS electrode contacts

Reference information:
Electrodes are now marketed with four contacts (M and S) or eight contacts (B and S). Classical electrodes are equipped with ring contacts (B, M and S). Newer electrodes are also provided with segmented ring contacts (B and S). Electrodes with segmented rings contacts are equipped with ring contacts at most superior and the most inferior contact while the middle contacts are each split into three segments. The contact length (cl) is equal (1.5 mm) for all electrodes. The intercontact spacing (is) is either 0.5 mm (B, M, S) or 1.5 mm (M, S).

The polarity of the contacts is one factor that determines the distribution of the current in the targeted brain region. Both the contacts on the electrode and the case of the IPG can be programmed as cathode (−), anode (+), and off (neutral). In a monopolar configuration, one contact on the electrode is set to cathode and the case of the IPG acts as an anode. Bipolar stimulation is characterized by selecting one electrode contact as anode and another electrode contact as cathode. The case of the IPG is neutral in a bipolar stimulation setting. In a multipolar configuration, one or more electrode contact(s) are used as anode and one or more electrode contact(s) are used as cathode. The current flows between the cathode(s) and anode(s). The polarity configuration has an impact on the current flow, and therefore, on the volume of tissue activated (Butson and McIntyre 2008). Figure 3 shows a schematic representation of systems operated in unipolar, bipolar and multipolar configurations.
