Glass pipette-carbon fiber microelectrodes for evoked potential recordings.
Current methods for recording field potentials with tungsten electrodes make it virtually impossible to use the same recording electrode also as a lesioning electrode, for example for histological confirmation of the recorded site, because the lesioning procedure usually wears off the tungsten tip. Therefore, the electrode would have to be replaced after each lesioning procedure, which is a ver...
متن کاملCarbon Fiber-based Microelectrodes and Microbiosensors
The chemically relatively inert carbon fiber (CF) has outstanding mechanical and electrical properties and provides an excellent base electrode for electrophysiological, electrochemical and biosensor applications on a micrometer or perhaps even on a submicrometer scale. CF microelectrodes have been used to record neuronal action potentials (spikes) since 1979 (Armstrong-James & Millar, 1979). T...
متن کاملCarbon fiber on polyimide ultra-microelectrodes.
OBJECTIVE Most preparations for making neural recordings degrade over time and eventually fail due to insertion trauma and reactive tissue response. The magnitudes of these responses are thought to be related to the electrode size (specifically, the cross-sectional area), the relative stiffness of the electrode, and the degree of tissue tolerance for the material. Flexible carbon fiber ultra-mi...
متن کاملFabricating and Evaluating Carbon Fiber Bundle Microelectrodes for Intramuscular Stimulation
INTRODUCTION Many neural processes, such as memory formation and learning, occur over a relatively long time frame. Conventional neural electrodes lose much of their accuracy over these time periods, due to multiple factors including glial cell encapsulation, micromovement in the brain, and neuron cell death. To address this problem, electrodes for long-term neural stimulation or recording must...
متن کاملPedot/go Carbon Fiber Microelectrodes for Dopamine Sensing
INTRODUCTION Dopamine (DA) sensing has become an important emerging technology due to the regulatory role of DA signaling in neurological diseases such as schizophrenia, addiction and Parkinson’s. However, due to its low concentration in the CNS relative to coexisting species such as ascorbic acid (AA), DA can be difficult to detect accurately. When using traditional electrodes, the recorded ox...
