Hearing Research Seminar: Neuroimaging and neuromodulation: Complementary approaches for identifying the neural correlates of tinnitus Event as iCalendar

5 - 6:30pm

Venue: Function Room 730-220, Building 730, Tāmaki Innovation Campus

The Section of Audiology and the Oticon Foundation Hearing Education Centre present "Neuroimaging and neuromodulation: Complementary approaches for identifying the neural correlates of tinnitus".

Functional imaging reveals that tinnitus is related to alterations in neuronal activity of central auditory pathways. Modulation of neuronal activity in auditory cortical areas can reduce tinnitus loudness and, if applied repeatedly, exerts therapeutic effects, confirming the relevance of auditory cortex activation for tinnitus generation and persistence. Imaging also indicates involvement of non-auditory brain areas, such as the fronto-parietal "awareness" network and the non-tinnitus-specific distress network consisting of the anterior cingulate cortex, anterior insula, and amygdala. Involvement of the hippocampus and the parahippocampal region suggests the relevance of memory mechanisms in the persistence of the phantom percept. Preliminary studies targeting the dorsolateral prefrontal cortex, the dorsal anterior cingulate cortex, and the parietal cortex with rTMS and tDCS confirm the relevance of non-auditory networks. These indicate the importance of brain stimulation as a complementary approach to neuroimaging for identifying neuronal correlates of clinical aspects of tinnitus.

Presented by: Professor Sven Vanneste , Department of Translational Neuroscience at the University of Antwerp

Professor Sven Vanneste is a neuroscientist whose research focuses on how an auditory conscious percept is generated. He makes use of different neuroimaging methods and techniques to visualize how the auditory brain functions and makes use of different non-invasive (eg transcranial magnetic stimulation, transcranial direct current stimulation) and invasive neuromodulation (cortical and deep brain stimulation) to modulate auditory phantom percepts.
