I am interested in exploring what types of information about speech sounds are represented in the brain and how they are represented and operated on in speech perception, production, and the perception-production interface.
To investigate these questions, both in feedforward and feedback stages, I am currently using the electrical neuroimaging method. I analyse source-localized brainwave data for effective connectivity, and also analyse voice data for behavioural outcomes. By analysing these two types of neurobiological time-series data, I can model the dynamic cortical processes of speech perception and speech-motor control.
In clinical applications, the findings from my studies may help provide the temporal and spatial information necessary to optimise the pulse parameters to realize accurate preoperative language mapping by navigated transcranial magnetic stimulation.
