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 [...]

Functional imaging of speech production

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).

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.

Neural correlates of speech production

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.
