Extended Data Fig. 6: Negative correlation between word frequency and evoked power.
From: Plasticity and language in the anaesthetized human hippocampus
Z-scored LFP power features were similarly computed for each trial, frequency band, and channel in the 4 patients that participated in the language task. In all 6 bands, power demonstrated a modest but significantly negative correlation with word frequency (p < 0.0001; Spearman’s correlation, n = 384 channels in each of 4 patients), contrasting the results of single unit analysis.
