Fig. 1 Neural decoding and patient control of imagined image presentation (IMAGE)
Caption
Electrocorticogram (ECoG) recordings were taken from 17 patients with epilepsy who had implanted subdural cortical electrodes related to visual perception. A decoder was trained to estimate the semantic meaning of the images that the patients were viewing from the intracranial ECoG recording using visual-semantic space. Based on the real-time inferred semantic information with the decoder, an image was displayed on a monitor placed in front of the patient. The patient then tried to display an image with instructed meaning by imagining it.
