IEEE-1214707 (pdf) Silicon-substrate intracortical microelectrode arrays for long-term recording of neuronal spike activity in cerebral cortex.
- 4 of the 6 implants (66%) remaining functional for more than 28 weeks (7 mo)
- Recording sites separated by 100um; at this site separation, adjacent sites may sometimes record the same unit.
- It is notable that in each case in this series was terminated due to reasons other than the microelectrode not recording unit activity. (SC LIn agrees, pc).
- around 80% of sites recorded neural activity.
