Eye Movements And The Neural Representation Of Visual Space
Funder

Funding Amount
$459,061.00
Summary
This project will investigate the brain mechanisms that underlie our ability to perceive the locations of objects using vision. This fundamental ability supports a range of important functions including visually-guided reaching, navigation during walking, and spatial awareness, but remains poorly understood. Using physiological, behavioural, and analytical methods, this project will fill a key knowledge gap in visual neuroscience and form a basis for a range of clinical and biomedical advances.
Ictal Characteristics Of Common Vestibular Diseases

Summary
vertigo is a disabling symptom affecting 1 million Australians at any given time. Acute vertigo is associated with abnormal eye movements or nystagmus, the pattern of which points to its origin. In this project, we extract the unique characteristics of distinct vertigo syndromes to enable their separation
Mechanisms And Pathways Leading To Saccadic Suppression In Primate Brain

Funding Amount

Summary
Only the central few degrees of the visual field are viewed in high resolution. Consequently, the eyes must be pointed at targets of interest using saccadic eye movements. Each saccade generates potentially disturbing image motion but this is never perceived: saccadic suppression. This project aims to characterise the neural basis of saccadic suppression using modern techniques. As a result, a prime question in Neuroscience for over 100 years can now be answered.
The Functional Organisation And Signals Of Motion Sensitive Neurons In The Middle-temporal Area Of Visual Cortex
Funder
National Health and Medical Research Council
Funding Amount
$405,337.00
Summary
Some nerve cells in the cerebral cortex are very sensitive to visual motion. These neurons direct eye movements and provide motion perception, but the "neuronal code" they carry is poorly understood. We will address this basic question in experimental studies of the primate visual system. This project will help us understand visual performance; poor motion vision is an early indicator of many neurological disorders and this knowledge can help develop methods for their detection and diagnosis.
