Can eeg's detect words?


Hello everyone !

I’m a computer science student and fascinated about neuroscience. I would like my bachelors final project to revolve around the topic. I would like to apply machine learning / data analysis on eeg raw data to read information from my brain.

Specifically, what I would like to do is think of concepts or words and detect that with my code. For example, I could think of an apple or a car, and the program would be able to detect what my thoughts were (obviously within a restricted domain).

I saw examples of eeg gadgets that detect simple concepts like up, down left and right, so I’m guessing it is at least somewhat feasible. What I wonder is up to which extent? What do you think?

Thank you in advance!


Maybe the question is a bit stupid, but I would still appreciate an answer since I am a complete beginner in this field and I need to know if the investment is worth it or not. :smile:



This is interesting.
Do you think it will work to detect whole words at once, instead of letter by letter? Say, from a pool of around 100 words? I guess the answer depends on the amount of precision the EEG provides.

So, my next important question would be: which EEG should I get to work on this? Are some of the popular options like Emotiv or Bitbrain, or should I contact Cognionics instead?


Some type of speller is the way to go. Here are some other links. Cognionics is very expensive. g.tec has a nice speller, but it is also way expensive. OpenBCI has good experience in this area,
