Research Interests

In broad strokes, our lab studies brain plasticity. We are asking questions such as, how does the brain adapt to changes in sensory input or to direct brain damage. We use converging techniques such as psychophysics, eye movement measurement, functional magnetic resonance imaging (fMRI) and transcranial magnetic stimulation (TMS) to examine the brain and behaviour. We have three separate but interrelated lines of research:

1) We study rare neurological patients with acquired brain damage resulting in visual object agnosia (the inability to visually recognize objects) or prosopagnosia (the inability to visually recognize a face). Using image-guided TMS, we are able to create temporary lesions in neurologically-intact participants to better understand object and face processing by transiently disrupting processing in various cortical regions of the face, object and scene processing networks.

2) We are one of the few labs in the world to study multisensory (visual and auditory) processing in unique ophthalmological patients who have had one eye surgically removed (enucleated) early in life, thereby disrupting binocular input to the visual system. We are examining low-level form vision and motion processing as well as higher-level face, object and scene processing. We also measure multisensory adaptation through behaviour and neuroimaging. This approach can reveal coding mechanisms in the brain that inform us about how intact sensory systems function.

Joy is the MRI Technologist for the 3T Siemens Tim Trio MRI scanner at the Neuroimaging Laboratory.  She has been working in MRI research for 10 years and continues to be amazed by the this non-invasive technology that allows us to peer into ourselves, both into our bodies and our minds (through fMRI).  Joy is also the Safety Officer for the facility, and holds training sessions on a regular basis at the facility.  Please contact Joy to sign up for a training session or to book time on the scanner.

Aman Ish Goyal is working as a MRI Analyst with the Neuroimaging Laboratory here at York University. He will be supporting the research in the Schneider Lab as well as in the Neuroimaging Lab at large. He is an Electrical Engineer by his undergrad and has an M.S. in Biomedical Engineering. He received his graduate training in Gulf War Syndrome Project’s Neuroimaging Laboratory at The University of Texas Southwestern Medical Center at Dallas, Texas, USA. While his work here at York University relates primarily to neuroimaging, all things related to Healthcare Technology interest him.
