Eeg right hemispheric slowing
WebCross-hemisphere effects were anticipated consistent with the principle of the left hemisphere activation having an inhibitory effect on the right and vice versa. Thus, more rapid changes in power on the left were hypothesized to downregulate changes in the right hemisphere power values, slowing growth. WebThe present study confirmed this for the EEG delta band (1-4 Hz): Activity in the waking state was pronounced over the hemisphere of the lesion in 11 stroke patients suffering from aphasia, but not in 10 healthy controls. Changes of abnormal slow waves patterns were tracked from 1-3 months to 2 years poststroke by recording the EEG five times ...
