BACKGROUND Intracortical electrode arrays that can record extracellular action potentials from small, targeted groups of neurons are critical for basic neuroscience research and emerging clinical applications. In general, these electrode devices suffer from reliability and variability issues, which have led to comparative studies of existing and emerging electrode designs to optimize performanc...

We studied the involvement of the electrophysiological localization of the subthalamic nucleus (NST) using a multi-unit recording technique by means of semi-microelectrode in a set of thirty Parkinson's patients who benefited from a bilateral stimulation of the NST and who were operated on under local or general anesthesia. The multi-unit recording technique by means of semi-microelectrodes app...

The drive-recorder records automobile accidents and/or near-misses data. To realize the practical use of drive-recorders in automobiles, a fleet test was conducted on 202 cars and trucks that were in regular use on roads. Some of the tested drive-recorders were video drive-recorders (VDR) equipped with a video recording unit to obtain visual data on accidents and near-misses from the driver's v...

Jackson A, Fetz EE. Compact movable microwire array for longterm chronic unit recording in cerebral cortex of primates. J Neurophysiol 98: 3109–3118, 2007. First published September 12, 2007; doi:10.1152/jn.00569.2007. We describe a small, chronically implantable microwire array for obtaining long-term unit recordings from the cortex of unrestrained nonhuman primates. After implantation, the de...

The tetrode, a bundle of four electrodes, has proven to be a valuable tool for the simultaneous recording of multiple neurons in-vivo. The differential amplitude of action potential signatures over the channels of a tetrode allows for the isolation of single-unit activity from multi-unit signals. The ability to precisely control the stereotaxic location and depth of the tetrode is critical for ...

OBJECTIVE Drug resistant focal epilepsy can be treated by resecting the epileptic focus requiring a precise focus localisation using stereoelectroencephalography (SEEG) probes. As commercial SEEG probes offer only a limited spatial resolution, probes of higher channel count and design freedom enabling the incorporation of macro and microelectrodes would help increasing spatial resolution and th...

Aims and Methods. Conducting a survey study of a large number of patients and gastroenterologists aimed at identifying relevant predictors of interest in digital recording and documentation (DRD) of endoscopic procedures. Outpatients presenting to the endoscopy unit at our institution for an endoscopy examination were anonymously surveyed, regarding their views and opinions of a possible record...

The inferior colliculus, the primary nucleus in the mammalian auditory midbrain, occupies a central position in the ascending auditory pathway. Nearly all ascending neural pathways converge and synapse in the central nucleus of the inferior colliculus (ICC). Further, the anatomical arrangement of axons and neurons in the ICC suggests the existence of functional regions which may play a role in ...
