On May 24-25, 2019, high school students from across Canada came to McMaster University to compete for the CIHR Canadian National Brain Bee championship. This competition tests knowledge of neuroscience and skills at patient diagnosis and neuroanatomy. Competitors represented local brain bees from across Canada: Victoria, Vancouver, Edmonton, Calgary, Saskatoon, Winnipeg, London, Waterloo, Guelph, Hamilton, Toronto, Kingston, Ottawa, Montreal, Halifax, and Newfoundland. The winner of this year's competition is Jenny Sun from the Edmonton Brain Bee. Congratulations Jenny! Jenny will represent Canada at the International Brain Bee in September in Daegu, South Korea.
