Is there an EEG brain signal that has specific features resulting from imagination? For example, if a subject sees a car and imagines that the car is moving left. Could we capture this signal and decrypt what was the person imagining?

    $\begingroup$ The first thing you need to do is find in the literature, or construct and validate, a sound definition of "imagination". $\endgroup$ – Krysta Oct 26 '14 at 19:29

    $\begingroup$ In experimentation, everything needs a validated operational definition. $\endgroup$ – Krysta Oct 26 '14 at 19:51
  • $\begingroup$ @Krysta , I'm sorry , you question seems hard to explain abstract thing like imagination , at least for a person who is specialist little far a way from cognitive science or neuroscience , but if you looking to the following paper , at page 8 the authors used the word imagination without definition , and what they did(which is explained in the same page ) are so close to what i want to do , thanks in advance. $\endgroup$ – Learner Oct 26 '14 at 20:21

Yes of course. Most work with eeg and imagination focuses on the inner voice and what people are telling themselves and thinking to themselves. Imagine (pun intended) if we could reach into the mind of a terrorist and as they think about plots. Its not really all that hard but its not at all covert at the moment (all the schizoiod type personalities can relax). With a bunch of electrodes connected to the brain we are able to transfer what one person's imagined actions into another persons head for execution. Its really crude at the moment but at some point it will revolutionize the way we think about communication, art, education and intimacy. Connecting to imagined visualizations would be simular only instead of involving the motor cortex it would work with the visual centers.

  • $\begingroup$ Thanks for your answer! , but i have a few questions , Is this signal has known characteristics/features that we can use it in the Brain computer interface , for example The P300 (or ERP signals in general ) signal could be extracted by the computers(Through signals processing and Artificial intelligence Techniques) , and there is a wide BCI research based on it. but I'm does not see a researches in BCI that use the imagination or inner voice signals , is there a kind of hardness in dealing with those Signals in BCI ? $\endgroup$ – Learner Oct 27 '14 at 16:11
  • $\begingroup$ @Learner thank you for the additional questions i will respond as soon as possible but briefly: Motivational mechanisms (BAS) and prefrontal cortical activation contribute to recognition memory for emotional words. rTMS effect on performance and EEG (alpha band) measures, Self-Organizing Maps Based Thought Recognition via EEG Brain Activity Monitoring $\endgroup$ – user6939 Oct 27 '14 at 21:43
  • $\begingroup$ thought recognition is the keyword i didn't include in the paragraph which you can plug into google scholar. $\endgroup$ – user6939 Oct 27 '14 at 21:44
  • $\begingroup$ @Learner was that one paper and keyword enough or would you like more? $\endgroup$ – user6939 Oct 28 '14 at 2:53
