Patterns of phase reset across brain locations. (a) Phase-locking spectrogram illustrating degree of phase locking across frequency and time. The color scale represents the log₁₀ (P) value associated with the null hypothesis that the phase values (across trials) are uniformly distributed. Activity recorded from an electrode in right inferior temporal lobe in participant 9 [Talairach coordinates: (L–R, A–P, I–S) = (+14, -54, -3) mm]. Green bars denote the onset of the orienting stimulus, blue bars denote the onset of the list items, and red bars denote the onset of the probe stimulus. (b) Phase-locking spectrogram from an electrode in right subcallosal gyrus of participant 1 [Talairach coordinates: (L–R, A–P, I–S) = (+19, +1, -13) mm]. (c) Phase-locking spectrogram from a depth electrode in the right hippocampus of subject 4 [Talairach coordinates: (L-R, A-P, I-S) = (+25, -27, -19) mm]. (d) Phase-locking spectrogram from a depth electrode in the right occipital cortex of subject 7 [Talairach coordinates: (L–R, A–P, I–S) = (+39, -74, 3) mm]. (e) Phase-locking spectrogram from an electrode in the right inferior temporal lobe of subject 2 [Talairach coordinates: (L–R, A–P, I–S) = (+35, -39, -16) mm].
