Deep brain stimulation (DBS) is a surgical therapy refers to a brain surgery that is meant to implant electrodes that send electric signals to areas in the brain responsible for body movements (Weerasinghe et al., 2019). Although DBS is considered safe, it has a lot of negative effects. The negative effects associated with DBS surgery include heart problems, breathing difficulties, bleeding in the brain, Seizure, and misplacement of lead (Weerasinghe et al., 2019).  Studies reveal that DBS increases the prevalence of conditions, such as dementia and cognitive decline.

Deep brain stimulation electrode implantation is a legally established practice for treating movement disorders and psychiatric conditions. However, the treatment is strictly reserved for patients whose symptoms are not cured by medications (Li et al., 2016). DBS entails creating small perforations in the skull to implant the electrodes (Li et al., 2016). The surgery is done under the skin in the chest and is done to implant the device that contains the batteries (Li et al., 2016). The device is turned on a few weeks after the surgery to help identify the best settings.

Measurement of neural activities during DBS employs methods such as local field potentials (LFPs) and electronically evoked compounds action potentials (ECAP). However, the ECAP is the commonly used method. When recording deep brain simulation data, stimulus artifacts are seen to cause prolonged saturation of the recording amplifier (James, 2019). This is a major challenge in the process of data recording as it has an effect of interrupting the main neural activities. Depending on aspects such as electrode property, amplifier, and stimulus parameters, the stimulus artifact may last for hundreds of milliseconds (James, 2019). It is worth noting that amplifier without saturation reduced the level of distortion relating to the ECAP signals, increasing fidelity (James, 2019). Therefore, when recording DBS data, it is important to minimize such contaminants.
