Multisensory integration of musical emotion perception in singing.

We investigated how visual and auditory information contributes to emotion communication during singing. Classically trained singers applied two different facial expressions (expressive/suppressed) to pieces from their song and opera repertoire. Recordings of the singers were evaluated by laypersons or experts, presented to them in three different modes: auditory, visual, and audio-visual.

Mental imagery of speech implicates two mechanisms of perceptual reactivation.

Sensory cortices can be activated without any external stimuli. Yet, it is still unclear how this perceptual reactivation occurs and which neural structures mediate this reconstruction process. In this study, we employed fMRI with mental imagery paradigms to investigate the neural networks involved in perceptual reactivation.
