A fully proven multi-wire recording/stimulation electrode, for in vivo chronic or acute implantations: increases the efficiency of recording and cell stimulation, enables long-term chronic implantations and functions as an individual unit or as part of an array. Twenty 8-Trodes in a 4 mm by 5 mm array will deliver 160 channels of single unit recording.

A recent study at Columbia University (Case, G.R. et al, Abstract, for 2002 Society for Neuroscience Annual Meeting) used 8-Trodes for recording and stimulation from rhesus monkey cerebrum. In 100 recording sessions, an average of 2.97 neurons were detected per electrode placement. An increase of 225% in stimulation count, over previous methods, was also observed. Electrodes were re-usable for three to six months. Individual impedances of electrode pads (sites) were stable in the 500-800 kOhms range over six months.
