Abstract

Magnetoencephalography will be used to non-invasively measure the regional changes in band-passed oscillatory power within human visual cortex, using a variety of parametrically modulated visual stimuli. An analysis technique known as Synthetic Aperture Magnetometry (SAM) will be used to investigate how the location, magnitude and frequency of stimulus-related power changes vary as a function of fundamental stimulus attributes such as retinotopic location, stimulus size, spatial/temporal frequency, velocity, contrast and stimulus duration. The results will be interpreted in the context of previous studies in several neuroscience domains i.e. single-cell recordings, other functional imaging modalities (fMRI/PET) and visual psychophysics.
