ruggiero-1August 2013

Welcome to Ruggiero Francavilla a PhD student developing a new in vivo approach using selective expression of genetically encoded probes in transgenic mouse models.


May 2013

Dr. Lisa Topolnik receives award for outstanding teaching - "Professor - Star 2012" from the Faculty of Science & Engineering of Laval University

MRC-2May 2013

Dr. Lisa Topolnik visited the group of Peter Somogyi at the Medical Research Council Anatomical Neuropharmacology Unit of the University of Oxford, England, UK.
During her time in the lab she collaborated with the group on the synaptic connections of hippocampal interneurons in the mouse. She will also interact with Marco Capogna and Karri Lamsa.


OlivierApril, 2013

Olivier Camiré obtained a PhD fellowship from NSERC to continue his fascinating studies on dendritic calcium signaling in hippocampal interneurons.


November 11-14, 2012
Dr. Lisa Topolnik talks at the Janelia Farm Research Conference - Neuron types in the hippocampal formation

EliseSeptember, 2011

Welcome to Elise Magnin, an undergraduate student who joined the lab for the research project.
She is working on the role of radixin, the alpha5 GABAA receptor subunit anchoring protein, in normal and epileptic hippocampus.


OlivierJanuary, 2011

Welcome to Olivier Camiré, third year biochemistry student, who has joined the lab for a research project.
Together with Simon Chamberland, he will be working on calcium signalling in dendrites of interneurons.
