Abstract

Various embodiments concern sensing bioelectrical signals using electrodes along a lead, the electrodes having a spatial configuration along the lead, generating signal data sets, one signal data set being generated for each bioelectrical signal, and graphically representing the electrodes and data representations of the signal data sets on a display. In various embodiments, each data representation indicates a parameter of a respective one of the data sets, the electrodes are graphically represented on the display in a spatial configuration representative of the spatial configuration of the electrodes along the lead, and each data representation is graphically represented on the display in spatial association with at least one electrode through which the bioelectrical signal on which the signal data set is based was sensed. The parameter can be indicative of the relative presence of a biomarker in the bioelectrical signals.
