Mechanisms And Pathways Leading To Saccadic Suppression In Primate Brain

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.
Spatial Coding In The Primate Cortex During Eye Movements.

Funding Amount
$428,720.00
Summary
Every time we move our eyes, objects in the world change their positions on the retina, yet to us, their positions remain perceptually unchanged. This project seeks to understand how neurons in the primate brain combine visual input with signals about eye position to construct this stable representation of external space. The findings will help us understand and-or rehabilitate a host of nervous system dysfunctions, including schizophrenia, stroke, and paraplegia.
Plasticity Of Sensorimotor Representations In Adult Primate Cortex

Summary
Cells in some regions of the brain, collectively known as the sensorimotor cortex, control our capacity to purposefully move the arms and hands. Damage to these regions in adults causes severe deficits. However, rehabilitative training can restore some control over the muscles. To understand how the brain circuits change to compensate for injury, and what effect rehabilitation may have on these changes, I will study cellular alterations in the movement control pathways in the cerebral cortex.
The neocortex is the region of the brain that underlies all cognitive functions. Mental disorders, such as schizophrenia, occur when the communication between nerve cells in the neocortex breaks down. We propose to make electrical measurements from the thin processes of neurons that receive input from widely separated neocortical areas to understand how areas of the neocortex are functionally interlinked, with the ultimate aim to identify how these processes are disturbed in mental disorders.
Staying Connected: Personalising Stroke Recovery And Rehabilitation Through New Technologies For People With Stroke Living At Home.

Summary
One in 4 people experience a stroke. On return home the person with stroke is challenged to sense, move, think, and engage in valued activities with an altered brain and body. Yet the current approach to ongoing recovery is limited. We propose to: monitor for markers of recovery using personalised sensors and artificial intelligence; deliver bursts of therapy at point of need, at home; and provide feedback through new technologies and a central hub...to stay connected, and to recover at home.
We stand without falling by using silent senses from muscles and the balance organs of the inner ear to unconsciously detect and control our movements. Since the leg muscles provide both the force and the sense, and critically rely on good circulation, they are vitally important. I propose to study how these sensory and muscle functions are used to control balance, posture and stepping reflexes, making it easier to identify older people who will fall and design new preventative strategies.
