Reduced phase locking to slow amplitude modulation in adults with dyslexia: An MEG study

► MEG response to amplitude modulation at 2 and 4 Hz rates shows two cortical sources. ► MEG response to amplitude modulation at 10 and 20 Hz rates has one cortical source. ► Phase locking at 2 Hz shows strong right auditory cortex activation in controls. ► Phase locking at 2 Hz shows bilateral auditory cortex activation in dyslexics.
