Grand mean surface Laplacian (CSD) event-related spectral perturbation (ERSP) plots (−10 to 800 ms; 1 to 30 Hz) at all 49 recording sites for 22 patients (top) and 20 controls (bottom) for each condition (nontarget, target, novel). Distinct event-related synchronization (ERS) for target and novel stimuli between 100 and 400 ms is evident for both groups at anterior sites. In contrast, event-related desynchronization (ERD) is most prominent for target stimuli between 400 and 800 ms over posterior sites, and appears to be reduced for patients compared to controls.
