Research

Visual perception and movement control

Dr. David Westwood is exploring the inner workings of the sensory and motor systems. He is particularly interested in how visual attention and eye movements relate to the control of arm and hand movements, how damage to the nervous system affects movement control, and how damaged systems recover with guided interventions. His findings will aid in the development of new treatments and assistive devices for people with movement disorders due to stroke, Parkinson’s disease, and other conditions that affect their ability to control skilled movements.

Dr. Westwood uses sophisticated eye tracking, motion capture and brain imaging technology to explore:

  • how lack of binocular vision affects arm movements
  • mechanisms underlying control of eye and arm movements
  • the nature of motor recovery after stroke

Dr. Westwood collaborates with various other members of AMAP and the Brain Repair Centre, and has been a co-investigator on a five-year, $1.7 million Atlantic Innovation Fund-supported project led by Dr. Gail Eskes to develop and test a cognitive repair kit for people with stroke and other neurological disorders. He's now involved in a new Heart & Stroke Foundation of Canada-funded spin-off project with Dr. Eskes to understand the behavioural and neural mechanisms of prism adaptation treatment for spatial neglect following stroke. Among other projects, Dr. Westwood is also part of a team that holds funding to develop a neurofeedback-based Intervention to reduce tremor in essential tremor.

Academic background

David Westwood completed a B.Sc. in kinesiology at the University of Waterloo, receiving the Governor General’s Silver Medal for highest grade point average. He then broadened his studies to encompass the mind, earning an MA and a PhD in psychology, also at Waterloo. His theses examined connections between visual perception and action, a line of enquiry he pursued through a postdoctoral fellowship at the University of Western Ontario. Dr. Westwood accepted a faculty position in the kinesiology program at Dalhousie University’s School of Health and Human Performance in 2002, followed by various adjunct appointments in the faculties of Science and Medicine and the IWK Health Centre.
