Cognitive Neuroscience of Memory Systems

Investigating the networks of brain regions that govern different kinds of memory

Research by using magnetic resonance imaging

Memory is the result of groups of brain regions working together


paula croxsonWe investigate the networks of brain regions that govern different kinds of memory. We know that memory is not localized to single brain regions, but instead is the result of groups of brain regions working together. To do this we examine the effect of changes to specific regions of the brain on the whole network, and correlate these network changes with behavior. We also work on the role of neurochemicals, such as acetylcholine, in memory. We accomplish this research by using magnetic resonance imaging in animal models, to look at changes in structure, function and connections – and by combining it with behavioral assessments.
