Abstract :
The extracellular potential simultaneous recording permits the investigation of the central nervous activity. The paper presents the design and manufacturing steps of a five electrodes microprobe for recording the electrical activity of neural cells and tissues integrated on the same chip with the electronics. The specific fabrication processes of the integrated microprobe are presented. An implantable neural microprobe is going to be developed to enable the correlation between electrical activity in the human nervous system and externally psychoelectrical stimuli. The electronics accomplish the separation and reduction of the biological noise recording.
