Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Measurement of the therapeutic window's boundaries when stimulating in specific angular directions, and comparison to those obtained when stimulating in all directions.
Tidsramme: up to one hour during surgery
|
A therapeutic window is defined as the difference between the electrical current threshold at which a desired therapeutic effect is obtained and the current threshold at which side effects appear.
