Time-frequency analysis of electroencephalogram series in the four experimental conditions.

<p>A: Event-related spectral perturbation (ERSP) from electrode P3. Black square frames indicate the time window and frequency for which there are significant differences between the agent and patient conditions; dotted black square frames indicate the time window and frequency for which there are significant differences between the high_relatedness and low_relatedness conditions. B: Topographies of the thematic relation effect of beta power (15–30 Hz) and the semantic relatedness effect of theta power (4–7 Hz).
