Extended Data Figure 4. Timing of the selectivity to hierarchical orthographic stimuli in the passive viewing task.

Extended Data Figure 4.

(a) Temporal representations of the two archetypal components generated from NNMF of the z-scores of words against each non-word condition. (b) Spatial map of the NNMF decompositions of the z-score word selectivity (207 electrodes, 20 patients). (c) Spatiotemporal representation of word vs non-word selectivity (non-word normalized to word activity) for each of the letter-form conditions. Electrode selectivity profiles were grouped every 20 mm along the antero-posterior axis in Talairach space. Each condition shows an anterior-to-posterior spread of word selectivity (red). FF: False Font, IL: Infrequent Letters, FL: Frequent Letters, BG: Frequent Bigrams, QG: Frequent Quadrigrams.
