Our research aims to enhance functional recovery in people with neurological and psychiatric disorders. This work spans the spectrum from studies in normal volunteers on the neural bases of human behaviour, to studies in clinical populations aimed at elucidating mechanisms of neuroplasticity, to clinical trials of promising therapeutic interventions. Current studies are conducted in the areas of Alzheimer’s disease, multiple sclerosis, and HIV-associated neurocognitive disorder.

This work draws on a variety of investigative methods, including: transcranial magnetic stimulation (TMS), structural and functional neuroimaging (fMRI), neuropsychological assessment, questionnaire and performance-based measures of functional ability. Interventions include repetitive TMS (rTMS), physical rehabilitation, and cognitive rehabilitation. Our research represents a true multidisciplinary effort involving teams of scientists and clinicians from different backgrounds, including psychology, neurology, physical and occupational therapy, biostatistics, geriatric medicine, and anesthesiology.

Studies using transcranial magnetic stimulation and cognitive assessments are carried out at Dr. Koski’s TMS laboratory located at the Gatehouse of the Allan Memorial Institute at McGill University Health Centre.

Studies using MRI and EEG are carried out at the McConnell Brain Imaging Centre of the Montreal Neurological Institute.
