Abstract:
Modern brain imaging methods now afford unprecedented opportunities for the in vivo study of central nervous system function. Positron emission tomography (PET) has been used as a functional imaging technique for more than a decade to study the distribution of cerebral haemodynamic changes associated with auditory stimulation, particularly in auditory cortex, in health and disease, in normal hearing subjects and cochlear implant patients. Although functional magnetic resonance imaging (fMRI) can now be used for many studies for which formerly only PET was suitable, PET possesses unique advantages. As well as its use in basic research, PET has considerable potential as a clinical assessment tool.
