Research
Research in the Richards laboratory focuses on the development, plasticity, and function of long-range connections of the cerebral cortex. The corpus callosum is the largest fibre tract in the brain of placental mammals and connects neurons in each cortical hemisphere. We investigate how cellular and molecular/genetic mechanisms regulate brain wiring during development and how brain wiring is altered in congenital corpus callosum dysgenesis (CCD).
CCD occurs in 1:4000 people and can result in profound changes in the structural architecture of brain connectivity due to long-range axonal plasticity that occurs during development. The lab investigates the underlying causes of CCD, how long-range axonal plasticity occurs and how these structural changes in brain wiring impact cognition and behaviour.
Professor Richards is a board member of the International Research Consortium for the Corpus Callosum and Cerebral Connectivity (IRC5) and a scientific advisor and patron of Australian Disorders of the Corpus Callosum (AusDoCC) support group.
In addition to her research, Professor Richards is a passionate advocate for neuroscience. She contributed to establishing the International Brain Initiative, the Australian Brain Alliance and the Australian Brain Bee Challenge and is a board member of the International Brain Bee and a member of the Dana Alliance for Brain Initiatives.
