Extended Data Fig. 3: Evolution of oddball encoding within the LFP.

a. Decoding accuracy as a function of trial position for both patients. Each point represents SVM accuracy within a set of 50 trials starting at the index location. Decoding accuracy for tone identity is shown in purple, and for oddball identity in green. Dashed line at 0.5 is chance. b. Euclidean distance between standard and oddball population response vectors comprising all channels across both patients (n = 756 channels), computed for each oddball trial, separately for responses within distinct frequency bands. Each datapoint (in grey) indicates Euclidean distance per trial, and lines show a linear fit with 95% confidence intervals. Analysis of cosine angle (not shown) demonstrated a highly similar trend.
