The Beginning
The process of neurosignaling and its parent technology, brain-computer interfaces, find their roots as far back as the 1970's. Studies on algorithms that determine impulses from motor cortex neurons have become more and more prominent. The goal of these studies is to understand and possibly emulate these movement signals on an "extension" of the human body (Georgopoulos, 1989).

Research and Development

Within work groups led by Schmidt, Fetz, and Baker, discoveries in the brains of monkeys, and their response to closed-loop operant conditioning, led way to the first successful BCIs (Alpert, 2008).This technology is just now receiving more widespread popularity, and with the evolution of computers, the functions to "read" thoughts are becoming more efficient (Stoever, 2009).Scientists like Adam Wilson demonstrated the progress of this technology. During an experiment, he successfully connected a BCI to the simple interface of the popular internet phenomenon Twitter in just one day. Of course, Twitter is a lot less invasive than giving back the sense of sight to someone, but it nonetheless proves the versatility of this technology(Stoever, 2009).
It must be noted that even though the technology is quickly progressing, it is still too sophisticated to be kept in a home environment (Stoever, 2009).
