Project Summaries
The goal of this study is to examine the changes in brain activity after a memory self-efficacy training program to better understand the mechanisms of memory self-efficacy. We will conduct a proof-of-concept six-week memory self-efficacy intervention in older adults with MCI, in order to demonstrate that self-efficacy impacts brain function. This will allow us to determine whether self-efficacy interventions may be a potential strategy for combating AD in the future.

Project Summaries
Our project will attempt to determine the relative importance of astrocyte or neuronal directed lactate generation on memory by modifying mouse models to either suppress or overexpress the lactate producing enzyme in either cell type. Using these newly created transgenic mouse models, we aim to understand the processes of production and utilization of lactate and its effect on memory and cognition in health and in AD across the lifespan. The outcome of our study may lead to entirely new clinical approaches to treating cognitive and neurodegenerative disorders via drugs which alter lactate metabolism.

Project Summaries
We are going to assess brain structure and function using magnetic resonance imaging (MRI) and positron emission tomography (PET) to study white matter inflammation and the density of synapses over time, alongside a behavioural assessment of motor and executive function. This kind of comprehensive assessment, especially using PET to measure synaptic density, has not been done before.

Project Summaries
We will be integrating this cognitive assessment with imaging of brain structure and function to understand the mechanisms by which a risk factor, in this case modifiable life stress, influences Alzheimer's disease-related decline. The resultant data will be integrated and disseminated using a new open-access neuroinformatics platform developed at Western (MouseBytes.ca), which will become a unique resource for open science investigations and set the standard for sharing of behavioural data across the world.
