Christophe Proulx

Christophe Proulx is an Associate Professor at the Department of Psychiatry and Neuroscience, Faculty of Medicine, Université Laval. He serves as Director of the Cellular and Molecular Neurosciences axis at the CERVO Brain Research Center. His research focuses on decoding neural mechanisms underlying emotional processing and depression, particularly involving the lateral habenula and serotonergic circuits.

Key research themes include:

• Emotional encoding in brain reward circuits
• Serotonin signaling in mood regulation
• Role of lateral habenula in depression
• Optogenetic and fiber photometry techniques
• Sex-specific stress adaptations
• Antidepressant mechanisms

Scientific trends from his publications show emphasis on lateral habenula dysfunction in mood disorders, advanced neurotechnology tools, chronic stress neuroplasticity, and translational neuroscience spanning psychiatry and molecular neurobiology.
