The temporal profile of multisensory enhancement. Left: Impulse rasters illustrating the responses of a multisensory SC neuron to visual (V), auditory (A), or combined visual-auditory (VA) stimulation. Right: Two different measures of the response show the same basic principle of initial response enhancement: multisensory responses appear enhanced from their very onset (i.e., as soon as inputs arrive). On top the measure is the mean stimulus-driven cumulative impulse count (qsum), on the bottom it is an instantaneous measure of response efficacy referred to as the event estimate.
