Today's catch for the implant technology section.
Rossi et al (2007) An electronic device for artefact suppression in human local field potential recordings during deep brain stimulation. Journal of Neural Engineering 4, p96-106. This paper describes 'FilterDBS' - an algorithm for filtering out the DBS stimulus artefact so that LFP recordings can be made during DBS.
Motta & Judy (2005) Multielectrode microprobes for deep-brain stimulation fabricated with a customizable 3-D electroplating process. IEEE Transactions on Biomedical Engineering 52(5), p923-933. To facilitate long-term DBS of the small and inaccessible rat STN the authors describe a novel DBS implant. This is particularly relevant to iPlant research since monoamine nuclei are also very small and inaccessible, even in humans.
Gross et al (2006) Electrophysiological mapping for the implantation of deep brain stimulators for Parkinson's disease and tremor. Movement Disorders Suppl 14, p259-283. A review of the various electrophysiological techniques used to finalize target selection during DBS surgery.

Journal of Clinical Neuroscience 14/7), p643-649.Rodriguez-Oroz et al (2005) Bilateral deep brain stimulation in Parkinson's disease: a multicentre study with 4 years follow-up. Brain 128(pt10), p2240-2249. Follow-up study of 69 DBS patients at four years.
Nielsen et al (2007) Chronic subthalamic high-frequency deep brain stimulation in Parkinson's disease--a histopathological study. European Journal of Neuroscience 14(2), p132-138. Limited histopathological changes in the vincinity of DBS electrodes appear to be related to the electrode itself rather than electrical stimulation.
