Abstract
Alterations of existing neural networks during healthy aging, resulting in behavioral deficits and changes in brain activity, have been described for cognitive, motor, and sensory functions. To investigate [...]

The findings of the present MEG study do not provide evidence for the hypothesis that auditory temporal processing, as measured by the decrement (short-term habituation) of the major auditory evoked component, the N1m [...]

This paper presents the first quantitative voxel-wise meta-analysis of swallowing-related brain function. Data analysis was performed with the activation likelihood estimation (ALE) approach, using the freely available software GingerALE.
Abstract
A quantitative, voxel-wise meta-analysis was [...]

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 [...]
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.

Aim: We tested the hypothesis that reduced nutritional status or the degree of tissue catabolism are associated with the presence of hepatic [...]

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.

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.
