Propofol Anesthesia Precludes LFP-Based Functional Mapping of Pallidum during DBS Implantation
Conclusion: GPi and GPe are distinguishable using LFP spectral profiles in the awake condition. Propofol obliterates this spectral differentiation. Therefore, LFP spectra cannot be relied upon in the propofol-anesthetized state for functional mapping during DBS implantation.Stereotact Funct Neurosurg (Source: Stereotactic and Functional Neurosurgery)

Electrode Penetration of the Caudate Nucleus in Deep Brain Stimulation Surgery for Parkinson ’s Disease
Conclusion: Cognitive outcome was not influenced by DBS electrode tracks penetrating the CN. It is both feasible and sensible to avoid electrode tracks through the CN when possible, considering its function and anatomical position. However, penetration of the CN can be considered without major concerns regarding cognitive decline when this facilitates optimal trajectory planning due to specific individual anatomical variations.Stereotact Funct Neurosurg (Source: Stereotactic and Functional Neurosurgery)
