Dr. Holahan uses an integrative neuroscience approach to study both endogenous and exogenous influences on neural structure and function in the context of behavior. Our lab examines the emergence of spatial information processing and long-term memory storage in rodents during development and associated axonal and dendritic changes. We also use transgenic mouse models to investigate potential novel therapeutic targets in the treatment of Parkinson’s disease. Finally, we study exogenous (environmental toxins, experimental brain injury, pharmacological manipulations) influences on brain function (immediate early gene expression, inflammatory markers) and structure (axonal and dendritic connectivity).
Eligible to supervise at the undergraduate and graduate levels.
Over the last six years, the research in the Holahan Lab has centered around the use of an integrative neuroscience approach to study influences on neural structure and function in the context of behaviour. The following are some of the areas of focus:
