Abstract

Brain activity was measured by magnetoencephalography to investigate the spatiotemporal stage of visual processing at which predictive and sensory integration begins. We examined the consequences of a visual mismatch between preliminary prediction and incoming stimulus. Following auditory cues (1000- and 1250-Hz tones) for prediction, congruent and incongruent images, pictures of two musical keys, were presented to volunteers. When they predicted visual inputs on the basis of preceding auditory cues, we detected a mismatch signal for predictive-sensory incongruities in the striate and extrastriate areas for 100-200 ms after image presentation. As this signal reflects a compatibility analysis, we propose that the integration process begins in these areas approximately 100 ms after image presentation.
