Representation of natural sounds in the human brain: Transforming acoustics into the semantics of sound sources in the environment – SoundBrainSem

Submission summary

Recognizing sound sources in the environment is a key function of the auditory system, and is fundamental to our well-being. Our brain achieves this feat by transforming what we hear into representations of the semantics of the sound source. The computational nature of this transformation is poorly understood. In this project, we will characterize it by measuring how three key properties of cerebral sound representations (spatio-temporal dynamics -- MEG; transfer between brain areas -- iEEG; differences across cortical layers -- high-field fMRI) are explained by a wide range of computational models ranging from acoustics to semantics to deep neural networks. By doing so, we will push forward our knowledge of how our brain transforms natural sounds into semantic representations of sound sources in our environment.
