Reported in this table are the number of studies (in parenthesis) that showed reduced and increased amplitudes or delayed latency ERD and ERS in the diseases compared to healthy controls with the number of studies supporting the finding in parenthesis.
*PD studies included in this table are only those that compared PD with healthy control groups with EEG and MEG recordings.
**Two articles studied ERD and ERS changes with healthy children (under the age of 18) compared to healthy adults.
