Current Research Interests
Human psychophysics and brain imaging
My main research work has focussed on human vision, both normal and abnormal, using psychophysical methods, MEG and fMRI. Some research interests are:
- MEG investigations of pattern processing, aiming to tease apart the contributions from each region of the brain, from the earliest responses to simple features of objects to the complex interactions needed to perceive whole objects and perform complex tasks such as reading.
- Motion perception has been a long-term interest, and was the area I first worked in as a research student using psychophysical methods. More recently I have used MEG and fMRI to study the brain regions responding to moving patterns and objects.
- Using computer simulations to find out how the signals measured using MEG result from the combined action of millions of brain cells, and how these link to what we see.
- The application of MEG to clinical conditions such as migraine, Amblyopia, and epilepsy, and other patient groups.
