Rapid Plasticity In Sensory Systems - Linking Neuronal Adaptation And Perception
Funder

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.
Context Is Everything – Understanding How Spatial, Temporal And Behavioural Context Affect Sensory Processing

Funding Amount

Summary
A possum in a tree is cute to see on a bushwalk, but scary to hear when we are trying to sleep. This illustrates that how we perceive a “target” is affected by “modulators” that are close in space or time to the target, or by the task at hand. Deficits in contextual modulation are apparent in many neurological conditions. This project will investigate the neural circuitry that mediates spatial, temporal and task-related contextual modulation.
A New Mouse Model That Determines The Effects Of A Unilateral Vestibular Prosthesis On Vestibular Plasticity.

Summary
Much like a cochlear implant restores auditory function, a vestibular prosthesis restores balance function. It is not clear whether the limited results from vestibular prostheses is due the device not stimulating one component (the otoliths) of the vestibular system essential for self-repair. We will test mutant mice that lack otoliths to determine the importance of stimulating the otoliths in restoring function. This work will shape the future direction of prosthesis development.
