Background: Although the posterior oral cavity and oropharynx play a major role in swallowing, their central representation is poorly understood.
Methods: High-field functional magnetic resonance imaging of the brain was […]
The following oral presentation, given at the Dysphagia Research Society 2008 in Charleston, SC, USA, presents a study on somatosensory processing of brief air-pulse stimuli. A more detailed description of this study can be found here.

Background. To characterise the neural correlates of intact vibrotactile working memory and attention, we conducted functional MRI in 12 healthy young adults. Participants […]
This is a presentation I gave at the Ontario Aphasia Interest Group Teleconference in December 2006. It summarizes the findings of my fMRI study on speech production in healthy younger adults (Neuroimage 2006;32(1):376-387). The presentation is available as Flash web presentation or as a pdf (6 MB).

Abstract
A combination of magnetoencephalography and proton magnetic resonance spectroscopy was used to correlate the electrophysiology of rapid auditory processing and the neurochemistry of […]
This study in Neurology asks if a complete infarction of the auditory cortex affects the magnetoencephalographic correlates of auditory processing in the contralateral, unaffected hemisphere. We found no evidence for changes in contralateral auditory processing, suggesting that the auditory system does not reorganize after a large unilateral infarction.

Clustered fMRI of speech production.
This poster depicts the neural network involved in speech production as found in 9 young adults, based on my paper in Neuroimage.

This fMRI study in Neuroimage investigates brain activation during the production of a vowel and consonant-vowel syllables in the magnet. For the reduction of speech-related artefacts, clustered image acquisition was performed. The study revealed the widespread neural circuitry involved in speech production.
