WebJan 18, 2001 · In the present study we evaluated the relationships between the P300 event-related potential and event-related desynchronization (ERD) of electroencephalographic alpha activity by simultaneously analyzing P300 as well as 7–10- and 10–14-Hz alpha ERD responses from auditory passive and active oddball conditions. We compared the effects … WebDec 2, 2024 · In the current study, we hypothesized that alpha event-related desynchronization (ERD) would be deficient during reward processing in SZ (i.e., less alpha suppression to wins, relative to losses), and that reward-related ERD deficits would correlate with negative symptoms. Further, as ERD is thought to reflect a …
