Leader: Dr Damian Holsinger

Research Topics
Neurodegenerative diseases

We investigate genes associated with Alzheimer’s disease, Parkinson’s disease and Down Syndrome.

  • Our investigations in Alzheimer’s disease have led to the development of a gene therapeutic approach using RNA interference that is currently undergoing pre-clinical assessment in our laboratory.
  • The investigations in Down Syndrome are focussed around two critical genes that are located on chromosome 21, the trisomy of which contributes to the Syndrome.
  • We have recently embarked on a project related to Parkinson’s disease that is investigating a key genetic mutation associated with the disease that is equally prevalent in both early and late onset forms of the disease. Understanding the contribution of this gene will enable us to develop therapeutic strategies.

Successful ageing

  • Centenarians are a key group of individuals that demonstrate resilience and successful ageing in the face of lifes’ travesties. These individuals must therefore have a unique genetic composition that has enabled them to successfully navigate the daily maladies of gene-environment interactions, which normally prove toxic to other individuals. We are currently investigating the presence of various allelic and single nucleotide polymorphisms that may contribute to successful ageing.

Neurodegeneration Research

Picture of Kay Double

Leader: Associate Professor Kay Double

Research Topics

  • Investigating why only certain brain cells are affected by degenerative disorders, with a focus on Parkinson’s disease. Characteristic features of individual cells, such as the expression of certain proteins, pigments, receptors or ion channels, may make ostensibly similar neurons more vulnerable in these disorders.
  • Investigating the implications of metal changes in Parkinson’s disease for neurogeneration and the potential of metal modification for novel therapies.
  • Developing new imaging methods to improve diagnosis of movement disorders, such as Parkinson’s disease and Restless Legs Syndrome.
  • Studying brain plasticity and how movement control is altered in movement disorders.
  • Investigating stem cells in the healthy and diseased brain and the potential of these cells for novel treatments for degenerative disease

Neuroscience Research Laboratory, Cumberland

Associate Professor Double is establishing a new laboratory facility at the Cumberland Campus for neuroscience research. The laboratory is scheduled for completion in the second half of 2013, with research conducted until this time at her laboratory at Neuroscience Research Australia in Randwick.

Respiratory Motor Control Research

picture of Ron

Leader: Dr Ronald Balnave

Research Topics
Research in this laboratory concentrates on physiological links between the midbrain and brainstem respiratory centres involved in control of respiration. The dorsal and ventral respiratory groups, interconnected networks of respiratory-related cells, are part of the neural system controlling respiratory rhythm generation and respiratory motor output. The work in the laboratory is attempting to locate cells in these centres and observe their firing patterns during “normal” breathing and to observe changes in these firing patterns when the respiratory system is perturbed by alterations to central or peripheral neural inputs.

Current works

  • Brainstem mechanisms in the control of breathing – production of apnea
  • Interactions between peripheral inputs and midbrain centres in the control of breathing – vagus nerve and midbrain PAG

Sensory Systems Research

Leader: Dr. Aaron Camp

Research Topics

  • Airplanes, submarines and even our humble phones use sophisticated guidance systems to allow them to navigate through the environment. Amazingly, vertebrates have used analogous systems for billions of years! These systems are our senses. My research investigates how sensory signals are combined to enable navigation through our complex world.
    (view Aaron's sensory systems flyer.)

Visual Neuroscience Research

Leader: Dr Jin Huang

Research Topics
If we ask: How do we see? How is the image processed? The answer lies in the eyes and rest of the brain.
Located at the back of the eye is the retina. It is light sensitive. It contains nerve cells (neurons) that are important in the first stage of visual perception and visual processing. One of the types of neurons in the retina is called ganglion cells. They project to other regions within the brain and are important in the modification of complex visual signals.

Ganglion cells also receive a variety of excitatory and inhibitory signals within the retina. Hence, the properties of ganglion cells depend on how these signals are integrated. An important aspect of this integration is related to the relative magnitude and timing of these inputs, as this helps to determine the spatial and temporal properties of ganglion cells.

However, we do not know at present exactly how these inputs to ganglion cells impact on their activity. To investigate this, we are using intracellular recording techniques to examine the changes in ganglion cells activity in response to different types of inputs. Our project also looks at the effects of drug-simulation on the responses of ganglion cells, as this can also help us in understanding the receptive filed properties of ganglion cells.

Current Work
Jin is currently working on the retina. Looking at the properties of ganglion cells using patch clamping techniques.
