Brain computer interfaces (BCI) aim to reconstruct what human beings perceive or imagine from their brain activities. In this episode, DigiSoc researcher Jingyuan Sun explains how brain activities can be decoded to reconstruct linguistic and visual perception, as well as how language and visual inputs are represented in human brain. He further talks about his experiments with neuro-imaging data recorded by fMRI, EEG and MEG in order to help people, e.g. with brain injuries, to communicate more efficiently with others. In the far future, we might even be able to communicate with each other without talking, just by thinking.
