A Role For The Pulvinar Nucleus In Visual Cortical Development And Plasticity

Funding Amount
$844,435.00
Summary
This project will investigate a part of the brain responsible for processing visual information, the pulvinar. This area has received little attention but has more recently been associated with the capacity for infants to recover vision following injuries such as stroke, as well as in mental health conditions such as schizophrenia. We will take a cell-to-system approach to uncover how this area develops and modulates the processing of visual information.
The Pulvinar Is Instrumental In The Development Of Visual Cortical Networks

Funding Amount

Summary
This Project will elucidate the mechanisms and brain structures involved in visual system development and how their perturbation in early life can lead to neurodevelopmental and cognitive brain disorders, such as Williams and fragile-X syndromes as well as dyslexia. Furthermore, it will demonstrate how the visual brain has a greater capacity to compensate and achieve preservation of vision following an injury in early life.
Studies Of The Effects Of Asymmetric Hearing Loss On The Brain

Summary
Hearing loss impairs the normal development and maintenance of auditory pathways. Irreversible pathologies persist when hearing is not restored in a timely manner. While cochlear implantation is the accepted treatment for profound sensorineural hearing loss, there is significant variability in outcomes. Some of this variability is linked to the degree of hearing asymmetry. Thus, we propose to study brain changes in the auditory system that accompany asymmetric hearing impairment.
Bilateral Cochlear Implants: Restoring Binaural Processing By Experience And Training With Binaural Cues

Funding Amount
$968,030.00
Summary
Cochlear implantation in both ears is increasingly common and while there are benefits, performance falls short of expectations, likely due to the degradation of the long-term deaf brain’s sensitivity to small timing differences of sounds reaching each of the two ears. By confirming the hypothesis that experience with high-fidelity timing information will improve performance, this study will drive the technical innovations required to maximise the benefits and investment of bilateral implants.
Functional Anisotropies In The Processing Of Orientation And Direction-of-motion By Human Visual Cortex
Funder

Funding Amount
$366,164.00
Summary
We will study patterns of activity in the human brain to identify the cortical signature of normal visual function. The correspondences between patterns of brain activity and the structure and motion of the visual image in the normal human brain will provide data against which brain activity in a range of disorders from amblyopia to schizophrenia can be assessed.
