Improved methods for construction of carbon fibre electrodes for extracellular spike recording.
Microelectrodes using single carbon fibres as the conducting element have been used since 1979 for electrophysiological measurements in vivo and in vitro. However, there is still considerable discussion about the manufacture of these electrodes, and no overall agreement as to the best way to minimise electrode noise. In this article we describe some revised methods for carbon fibre electrode manufacture, which we believe, gives the lowest noise performance for spike recording in vivo.
