The importance of electrode location in cochlear implantation [PDF]
Laryngoscope Investigative Otolaryngology, 2016 ObjectivesAs indications for cochlear implantation have expanded to include patients with more residual hearing, increasing emphasis has been placed on minimally traumatic electrode insertion. Histopathologic evaluation remains the gold standard for evaluation of cochlear trauma, but advances in imaging techniques have allowed clinicians to determine ...

Scaling of Electrode-Electrolyte Interface Model Parameters In Phosphate Buffered Saline
, 2014 We report how the impedance presented by a platinum electrode scales with the concentration of phosphate buffered saline (PBS). We find that the constant phase element of the model scales with approximately the log of concentration, whereas the ...

Automatic Extraction of Implanted Electrode Grids [PDF]
, 1999 It is common in epilepsy surgery to implant grids and strips of electrodes between the skull and brain or inside the brain, in order to localize functional areas. MR scans are currently used for a variety of image-guided surgical planning tasks, including the localization of the electrode grids.

Cerebral Tissue Response to Electrode Implantation [PDF]
Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 1978 SUMMARY:Tissue response to platinum electrodes was assessed after an eight-day implantation period. The regions of study included the cortical areas at the opercular gyri and at the sulcus parielo-occipitalis externus, as well as the sub-cortical white matter in these areas.Perivascular and intraparenchymal hemorrhagic lesions as well as edematous ...
