Fig. 1From: Neural synchronization deficits linked to cortical hyper-excitability and auditory hypersensitivity in fragile X syndromeExample averaged virtual channel created by weighting the grand average epoched EEG data by the spatial PCA component, with inset PCA spatial component topography. Chirp stimulus amplitude modulation and timing is presented below. Note the increase in oscillation frequency in the PCA component waveform that matches the increase in chirp modulation frequency in the stimulus belowBack to article page
