Abstract:
AIM:With the development of microelectronics and the microsurgery,it becomes possible to directly extract all kinds of information from the brains of organisms.How to establish a communicative pathway that does not dependent on human brain and human tissues between human brain and computer?Hence,we explored a design project of an implantable system that could be reasonably applied in the extraction,transmission and control of the cranial neural electric signals in brain computer interface(BCI). METHODS:To bring out a design project of an implantable electric system for the extraction,transmission and control of the cranial neural electric signals through the application of the latest microelectronic techniques into the domain of the extraction of brain electric signal and to discuss in detail the key technique,difficulty and possible solutions involved in the projects. CONCLUSION:The proposed project can collect cranial neural electric signals from different depth within 16× 16 with the data precision of 12 bit,which is a closed loop control system.
