This line of research, carried out in close collaboration with the group of Prof. Stephanie Clarke (Neuropsychology and Neurorehabilitation Service, CHUV-UNIL), identifies the spatio-temporal brain dynamics by whcih sounds are recognized as objects. This includes, but is not limited to, categorical discrimination, priming/learning, vocalization discrimination, action-related associations, as well as the interplay between sound identity and sound localization on object processing.
The neural mechanisms that allow conscious access to incoming sensory stimuli has been mainly investigated in the visual and somatosensory modalities. In the auditory domain, this research has been based almost exclusively on linguistic materials. This project identifies the neural mechanisms that link the sensory evidence to the perceptual decision using various types of auditory stimuli. In particular I seek to understand how auditory stimuli are represented as a function of subjects' conscious access, experimental task and context, and how these representations relate to the perceptual decision.
This line of research investigates how the spatial position of sounds is encoded and how these representations can be made plastic via training/learning. This is of particular relevance in clinical populations in whom spatial representations are impaired and disrupt not only spatial analysis of auditory scenes, but also functions linked to object recognition. This work is carried in close collaboration with Prof. Stephanie Clarke (Neuropsychology and Neurorehabilitation Service, CHUV-UNIL) and Dr. Lucas Spierer (Neurology Department, University of Fribourg).
