There has been a recent break-through in brain computer interface research with the successful trial of BrainGate; an implantable chip that records electric activity directly from cortex. Although BrainGate is an invasive tool and subjects need to get surgery to get started, there are many volunteers. It is like a beginnings of new era where science fictions meets reality.

There's also some progress in non-invasive brain-computer interface technologies. A team of cognitive neuroscientists including John Kounios of Drexel University used EEG to identify Aha signal. A recent study use this technique to enable humans to sort/find images much faster. A computer monitors the human subject while he is looking at a series of images and computer captures much before then the subject himself if he has found what he is looking for.

All these tell me one thing, we are certainly in the "stone age" of cognitive sciences and the way we live will change (big time) after we understand more about how brain works and invent tools to intervene....
