From: Voluntary control of semantic neural representations by imagery with conflicting visual stimulation
a Locations of subdural electrodes are color-coded for each subject who participated in this study (n = 21). b ECoGs were acquired in real time to infer a semantic vector of 1000 dimensions in the visual semantic space from power in the high-γ band. An image that had the nearest semantic vector to the inferred semantic vector was presented to the subject as a feedback image. Because of copyright restrictions, the actual images used in the tasks have been replaced with illustrations throughout this paper. Details of the creation of the illustrations are presented in “Methods”.
