Fig 5. Pre-stimulus SME for words pooled across both modalities.

(A) Time-frequency illustration of the pre-stimulus SME pooled across modalities. Plotted is the percentage change between successful and failed retrieval averaged across all frontal, temporal, and central electrodes. (B) Depicted is the topographical distribution of the significant clusters in the low beta frequency band over time with significant data points being marked by a white * (p = .041, one-sided).
