In the project “Tip of the tongue: a BCI for speaking”, which is a part of the BrainGain research programme, we are working towards creating a Brain Computer Interface (BCI) system for speaking. According to the current linguistics theories, speech production consists of multiples stages: first a lexical item is selected, then its form is encoded for articulation. This means that the patterns of neuronal activity that underline lexical selection can be used as an input for a BCI system. The basis for the proposed BCI system is the online decoding of neural signatures of concept representation. Currently, we are working on an offline prototype for the decoding from EEG signals and fMRI brain images.
