摘要
Objective: To find out whether 14 16 year old reading and writing impaired pu pils have atypical EEG activation patterns during reading. Methods: EEG correlat ion indices (EEGCIs), based on the waveform characteristics of twoEEG signals, w ere used as measurers of slow joint activation of cortical regions during readin g in pupils with reading and writing impairment. Results: Reading was associated with high EEGCIs within the right hemisphere in reading and writing impaired pu pils. The finding is analogous to the results of an earlier study [Byring, Elec t roencephalogr. Clin. Neurophysiol. 63 (1986) 1] in boys with spelling disabilit i es. The activation in the right hemisphere might represent a compensation for a left hemisphere dysfunction in pupils with reading and writing impairment during reading, as suggested by a number of functional neuroimaging studies. T his interpretation was corroborated by high EEGCIs especially in those impaired pupils who had a good occupational outcome. Conclusions: EEGCIs during reading a re high within the right hemisphere in pupils with reading and writing impairmen t. Significance: High EEGCIs within the right hemisphere during reading might be considered neurophysiological markers for reading and writing impairment.
