A method for preparation of a metal microelectrode for recording neural signals

摘要

PURPOSE: A method is provided to be capable of making a metal micro electrode by using a glass micro pipet as a mask and removing an insulation film of a tip part of an electrode using oxygen and acetylene torch. CONSTITUTION: A method comprises forming one end of a metal rod(10) so as to have a sharp shape, forming an insulation film(20) on a surface of the metal rod, forming a glass tube(30) by extending and cutting a glass micro pipet, inserting in the glass tube the metal rod on the surface of which the insulation film is formed, heating a tip part of the metal rod which is exposed at an outside of the glass tube, and removing the glass tube.
