Abstract:

Functional imaging techniques, such as Positron Emission Tomography (PET) and functional Magnetic Resonance Imaging (fMRI), have enabled neuroscientists to elaborate how the human brain solves the formidable problem of decoding the speech signal. In this paper I will outline the properties of primate auditory cortex, and use this as an anatomical framework to address the data from functional imaging studies of auditory processing and speech perception. I will outline how at least two different streams of processing can be seen in primary auditory cortex, and that this apparently maps onto two different ways in which the human brain processes speech. I will also address data suggesting that there are considerable hemispheric asymmetries in speech perception.

Presenter:

Sophie K Scott is a Chair in Cognitive neuroscience at UCL, and is the group leader of the Speech Communication group at the Institute of Cognitive Neuroscience. She has worked in speech perception and production for over seventeen years. Following a PhD in speech rhythm at UCL, she worked at the MRC APU in Cambridge, getting involved in the neuroimaging of speech perception, as well as work on the expression of emotion in the voice. Her research covers the neural basis of speech perception, with specific projects including the nature of acoustic-phonetic representations in auditory cortex, the roles of streams of processing in the processing of speech, speech perception and production links, the nature of hemispheric asymmetries in speech perception, and the roles of learning and top-down modulation in auditory cortex. She is also starting projects working with auditory implant patients. Her work is funded by the Wellcome Trust, as well as Marie Curie and the ESRC. WebSite: http://www.icn.ucl.ac.uk/
