BRAIN STIMULATION AND SENSING

Devices, systems, and techniques are disclosed for managing electrical stimulation therapy and/or sensing of physiological signals such as brain signals. For example, a system may assist a clinician in identifying one or more electrode combinations for sensing a brain signal. In another example, a user interface may display brain signal information and values of a stimulation parameter at least partially defining electrical stimulation delivered to a patient when the brain signal information was sensed. Described herein is a method comprising: obtaining, by processing circuitry, brain signal information for at least one electrode combination of a plurality of electrode combinations of one or more electrical leads; determining, by the processing circuitry and based on the brain signal information, a respective frequency for the at least one electrode combination; outputting, for display, a plurality of selectable lead icons, wherein each selectable lead icon of the plurality of selectable lead icons represents a different electrode combination of the plurality of electrode combinations; outputting, for display, the respective frequency determined for the at least one electrode combination in association with the respective selectable lead icon associated with the at least one electrode combination; receiving user input selecting one selectable lead icon of the plurality of selectable lead icons; and responsive to receiving the user input, selecting, by the processing circuitry and for subsequent brain signal sensing, a sense electrode combination associated with the one selectable lead icon selected by the user input. Also described is an external programmer configured to perform the method. L'invention concerne des dispositifs, des systèmes et des techniques permettant de gérer la thérapie par stimulation électrique et/ou la détection de signaux physiologiques tels que les signaux cérébraux. Par exemple, un système peut aider un clinicien à identifier une ou plusieurs combinaisons d'électrodes pour détecter un signal cérébral. Dans un autre exemple, une interface utilisateur peut afficher les informations du signal cérébral et les valeurs d'un paramètre de stimulation définissant au moins partiellement la stimulation électrique délivrée à un patient lorsque les informations du signal cérébral ont été détectées. L'invention concerne un procédé comprenant : l'obtention, par des circuits de traitement, d'informations de signal cérébral pour au moins une combi
