In January 2008, Cornell University researchers succeeded in creating the moth cyborg. From LiveScience:
Cornell University researchers have succeeded in implanting electronic circuit probes into tobacco hornworms as early pupae.
The hornworms pass through the chrysalis stage to mature into long-lived moths whose muscles can be controlled with the implanted electronics. The research was showcased at MEMS 2008, an international academic conference on Micro-Electrico-Mechanical Systems that took place from January 13-17 in Tucson, AZ.
Man has mastered the moth brain! Well, mastered may be too strong a phrase. But we can, evidently, cause tobacco hornworm blade muscles to move via a "driving voltage of 5 volts."
