Extended Data Fig. 7: Electrode contributions to decoding performance.
From: A high-performance neuroprosthesis for speech decoding and avatar control
a, MRI reconstruction of the participant’s brain overlaid with the locations of implanted electrodes. Cortical regions and electrodes are colored according to anatomical region (PoCG: postcentral gyrus, PrCG: precentral gyrus, SMC: sensorimotor cortex). b–d, Electrode contributions to text decoding (b), speech synthesis (c), and avatar direct decoding (d). Black lines denote the central sulcus (CS) and sylvian fissure (SF). e–g, Each plot shows each electrode’s contributions to two modalities as well as the Pearson correlation across electrodes and associated p-value.
