Javad Karimi Abadchi, PhD

Postdoctoral Researcher

I am Javad Karimi Abadchi, a postdoctoral fellow in the Brandon Lab at McGill University. Prior to joining the Brandon Lab, I earned my PhD degree at the Canadian Centre for Behavioural Neuroscience/University of Lethbridge under supervision of Drs. Majid Mohajerani and Bruce McNaughton. My PhD thesis focused on studying the spatiotemporal patterns of the neocortical activity around hippocampal ripples, with implications for memory consolidation. In the Brandon Lab, I run two projects: 1) studying the dynamics of the brain head direction system while it anchors itself to the changing external. 2) investigating the mechanisms involved in the representational drift in the cortex. To accomplish this, I use a combination of miniscope calcium imaging, electrophysiology, optogenetics, chemogenetics, behavioural assay, and advanced computational and analytical techniques.
