An accuracy system configured to determine the accuracy of a stereotactic system The accuracy system is configured to determine a displacement between a pointer tip positioned by the stereotactic system and a target point defined by a phantom base. The accuracy system is configured to mechanically engage the phantom base when the phantom base mechanically engages the stereotactic system to determine the displacement. In examples, a gauge support mechanically engages a pin of the phantom base and determines the displacement using one or more visible indicia. In examples, a gauge frame supports one or more cameras and determines the displacement using a first image and a second image obtained by the one or more cameras. The accuracy system provides an output viewable by a practitioner to indicate the determined displacement.

Devices, systems, and techniques are described for adjusting therapy parameters defining electrical stimulation therapy. An example system includes a stimulation generator comprising a voltage stack configured to provide a stack voltage based on a multiplier of a battery voltage and processing circuitry. The processing circuitry receives a first set of parameter values that use a first stack voltage of the voltage stack to provide a first electrical stimulation defining a first therapy. The processing circuitry also determines, based on a second stack voltage lower than the first stack voltage, a second set of parameter values that define a second electrical stimulation, the second set of parameters defining a lower amplitude of electrical stimulation. Additionally, the processing circuitry controls the stimulation generator to deliver the second electrical stimulation according to the second set of parameter values using the second stack voltage of the voltage stack.

A method for determining an efficacy of medication treatment for a patient includes determining, by one or more processors, based on a local field potential (LFP) activity of the patient, when the patient takes medication and/or a duration of when the medication is effective. The method further includes outputting, by the one or more processors, an indication of when the patient takes the medication and/or the duration of when the medication is effective to facilitate a treatment for the patient.
