Figure 5. Antero-posterior differences in the timing of frequency and lexicality effects.

Figure 5.

Temporal (a,b,c) and spatial (d,e,f) representations of the two archetypal components generated from the NNMF for the contrasts of words vs non-words in the passive viewing task (a,d; 207 electrodes, 20 patients), words vs pseudowords (b,e) and high (HF) vs low (LF) frequency words (c,f) during sentence reading (196 electrodes, 20 patients). Vertical dashed lines denote word offset time. Spatial representations (d,e,f) are coloured based on the weighting of their membership to either component. Size is based on the magnitude of the contrast between experimental conditions.
