Harnessing the brain's plasticity to restore memory and cognitive function

We are studying the mechanisms that control the strength of brain cell connections, or synapses, and how this fundamental property, known as synaptic plasticity, affects brain function. The work is critical for understanding the cellular basis of learning and memory in health and disease. Our work aims to find treatments to restore behavioural and cognitive function in people with Alzheimer’s disease, mental illness and neurodevelopmental disorders.

Our research focuses on the hippocampus, a brain region critical for learning and memory. Electrophysiological and imaging recordings are used to investigate two main forms of synaptic plasticity, known as long-term potentiation (LTP) and long-term depression (LTD). In some of the work, our team employs disease models to study the genetic and molecular signalling pathways that go awry.  

We are designing and testing new therapies that promote healthy aging and others that aim to combat disease and restore cognitive function. As most neurological, cognitive and psychiatric illnesses involve impairments in neuronal signalling and neuronal plasticity, this research holds great promise in helping the millions of people who are afflicted with a variety of brain disorders.
