Re-engineering The Future Of Electrophysiological Measurements And Brain-Machine Interfaces Using A Novel Multi-Optrode Array
Funder
National Health and Medical Research Council
Funding Amount
$731,557.00
Summary
This proposal will develop scientific instrumentation to enable next generation interfacing with the heart and brain using light instead of electricity. Multichannel optical arrays will be fabricated using advanced materials and a control system developed and tested experimentally. The cost-effective technology will enable researchers to enhance our knowledge of the heart and brain with evolving optical approaches and offers future clinical applications for heart rhythm disorders and epilepsy.
Development Of Endpoints For Catheter Ablation Of Non-mappable Scar-related Ventricular Tachycardia.

Summary
Ventricular tachycardia is a dangerous heart rhythm disturbance that affects people with scarring in the heart such as those with prior heart attacks or heart failure. Catheter ablation procedures, using wires passed from the groin, can be used to burn the short-circuits related to the scar. However in the majority of cases, it is very difficult to know when enough burning has been performed. This project aims to develop and validate several electrical and imaging endpoints for this procedure.
Cortical Neuroprosthesis To Restore Visual Perception To Bling Patients.

Funding Amount
$189,250.00
Summary
We will develop a medical device to restore visual perception to profoundly blind patients. This device will act to electrically stimulate the visual area of the brain. Electrical stimulation of this area leads to the visual perception of small spots of light in patients who are otherwise blind. By correlating the stimulation of the brain, which leads to the perception of spots of light, with an image of the surrounding environment acquired by a camera and digitally enhanced, we aim to provide b ....We will develop a medical device to restore visual perception to profoundly blind patients. This device will act to electrically stimulate the visual area of the brain. Electrical stimulation of this area leads to the visual perception of small spots of light in patients who are otherwise blind. By correlating the stimulation of the brain, which leads to the perception of spots of light, with an image of the surrounding environment acquired by a camera and digitally enhanced, we aim to provide blind patients with a very basic visual perception of their surroundings.Read moreRead less
Rapid Plasticity In Sensory Systems - Linking Neuronal Adaptation And Perception

Funding Amount
$650,810.00
Summary
The activity of individual sensory neurons in the brain is surprisingly variable and continuously changing. It is unclear how reliable perception of the world can be generated from the activity of “noisy” neurons, and it remains unclear why neuronal sensitivity should change in the first place! This project will give insights into how groups of sensory neurons collectively overcome their intrinsic variability to support reliable visual perception.
