ELECTRODE FOR EXTRACELLULAR RECORDING

摘要

PROBLEM TO BE SOLVED: To provide an integrated multiple electrode of high strength for extracellular recording capable of stably recording the electric activities of neurons, etc., for a long period and can be easily reused. SOLUTION: The integrated multiple electrode for extracellular recording is provided with a plurality of micro-electrodes arranged on a substrate and a wiring part capable of providing electric signals for the micro-electrodes or leading out electric signals from the micro-electrodes. The micro-electrodes each comprise a porous conductive material in their surfaces, and their impedance is equal to 50 kΩor less.
