Focal electroporation of the adult SVZ with needle electrodes.
(a) Schematic representation of focal electroporation. (b,c) The electrodes for focal electroporation. 33G Hamilton syringe and a needle type electrode (CUY-200S) are connected to the electric stimulator or electroporator. The metal needle of the syringe is insulated except for the tip and bottom. The anode clip is touched to the bottom of the gauge when electric pulses are applied to the animal.
