Semantic-association theta power. (A) theta-Power change from baseline for one bipolar contact per patient at the context-defining word (i.e., highest semantic association, high), the preceding word (pre), and the following word (post). The LSA strength for each word with the target picture name is shown below. (B) Participants’ t-values for the comparison between theta power at the context-defining word (“high” in A) and the previous word (“pre” in A) for one bipolar contact per patient. Positive values indicate that theta power increases at the context-defining word. An asterisk indicates that the power changes were significant at P = 0.005.
