The McGill-Mouse-Miniscope (M3) Touchscreen Behaviour Platform is an integrated imaging and behavioral neuroscience research laboratory at the Douglas Research Centre. Its primary function is to enable advanced research in behavioral neuroscience by combining sophisticated touchscreen-based assays with cutting-edge miniscope imaging technology in freely moving rodent models. The M3 platform integrates state-of-the-art miniscope technology, which allows for in-vivo calcium imaging of neuronal activity in specific brain regions of freely moving animals during complex behaviors. This is coupled with advanced touchscreen behavioral paradigms that enable automated, high-throughput testing. These paradigms are designed to assess various aspects of rodent behavior, including learning, memory, motivation, and cognitive control, providing precise correlation between neural activity and behavioral outputs. This platform is an invaluable tool for researchers seeking to unravel the neural circuits underlying diverse brain functions and dysfunctions, particularly within the context of mental health and neurodegenerative disorders. It significantly advances studies investigating how genetic factors, environmental influences, and stress collectively impact brain function and behavior, offering a deeper and more integrated understanding of neurobiological mechanisms. In addition to its core technologies, the M3 platform likely provides specialized software for the acquisition, processing, and analysis of both behavioral and imaging data. It offers expert consultation on experimental design and data interpretation for complex neuroscience studies. The unique capability of miniscopes to enable chronic imaging of neuronal activity during naturalistic behaviors provides unprecedented opportunities for longitudinal studies and real-time insights into brain-behavior relationships.
