Figure 4. Endogenous EEG oscillations can improve prediction of hit rate irrespective of cue.

Figure 4

Offline-analysis of average EEG power across subjects revealed significant increases in power in the 1 s interval prior to ‘hit’ trials vs. ‘miss’ trials, for both attend-left and attend-right conditions (60–100 Hz band; less consistent results were observed in other bands, data not shown). This oscillatory activity may reflect generalized states of concentration or arousal, and could be used in combination with ear-specific neural bias states in future. Data were normalized by mean power across conditions for each subject prior to group averages. White numbers indicate total number of trials per condition, summed across twenty-one subjects. Error bars indicate standard error.
