Visual dysfunction, brain plasticity, and recovery

Research overview

I principally study visual dysfunction in neurological disease, particularly stroke.  My focus is on brain plasticity and the mechanisms underlying recovery of visual function, with the aim of enhancing recovery, for example through neurorehabilitation.

I have also published studies on the role of striatal dopamine in cognition, and cognitive screening (the TYM test, www.tymtest.com).

Publications are available through my ResearcherID: E-5288-2010 (roll over the badge below)


Key words

Neurorehabilitation, dopamine

Key findings

2009.  With colleagues in the Stroke Research Group and Wolfson Brain Imaging Centre in Cambridge University, I developed a new method for tracing the optic radiations in individual subjects and patients, using MRI fibre tracking methods (tractography) and comparing the resulting images with each other and with anatomical reference data.

2008.  At the Behavioural and Clinical Neurosciences Institute in Cambridge University, I found evidence for optimal dopamine levels in subregions of the human striatum, for specific cognitive functions.  This has relevance for cognitive function in attention deficit hyperactivity disorder and Parkinson's disease in particular.

2004.  In the Department of Physiology, Development and Neuroscience, in the University of Cambridge, I used computational modelling to provide evidence in support of the theory that the mammalian visual system is adapted to the statistical properties of everyday natural images.
