Talk 1
Alexandre Guet McCreight
Centre for Addiction and Mental Health
Talk title: Linking age changes in human cortical microcircuits to impaired brain function and EEG biomarkers
Speaker Bio:Alexandre Guet-McCreight earned his PhD in Computational Neuroscience from the University of Toronto, under the supervision of Dr. Frances Skinner, with a focus on biophysical modeling of inhibitory hippocampal cells. After a postdoctoral period at the Krembil Brain Institute, he joined Dr. Etay Hay’s lab at the Center for Addiction and Mental Health and KCNI, where he integrates biophysical modeling and computational approaches to uncover digital biomarkers of depression, cognitive aging, and related pathologies. His research is supported by a CIHR Fellowship. More details can be found at https://agmccrei.github.io/personal_website/
Talk 2
Theresa Wiesner
Aix-Marseille Université
Talk title: Non-synaptic exocytosis along the axon shaft and its regulation by the submembrane periodic skeleton
Speaker Bio:In the early years of my bachelor’s, I got fascinated during an internship with functional assays such as field recordings to study neuronal cell behaviour. I got hooked on doing my master in Bio-photonics to learn functional imaging. During my Ph.D. in Biophotonics at Université Laval, Quebec, I combined functional assays, super-resolution imaging and computational tools to quantitatively assess and explore synaptic protein organization and remodeling due to synaptic plasticity.
My ambition is to overcome the current inability to directly link nanoscale protein organization to neuronal function, which impedes our understanding of fundamental cellular mechanisms and our capacity to alleviate misorganization in neurological disorders. Currently, I am a postdoctoral fellow in the NeuroCyto team at the Institute of NeuroPhysiopathology (INP) in Marseille, France. Here I am studying the role of actin/spectrin submembrane scaffold in axonal shaft exocytosis by combining live-cell and super-resolution microscopy.
