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.
Interaction Of Thalamic And Cortical Activity In The Primate Visual System

Funding Amount

Summary
We recently discovered that a primitive part of the visual pathway shows rhythmic nerve cell activity similar to slow brain waves recorded in sleep, anaesthesia, and epilepsy. We now plan to discover whether these primitive cells help to generate brain waves by measuring the timing of their activity together with brain waves in different visual and non-visual parts of the brain. This project will contribute to understanding the role of brain waves in normal brain function and epilepsy.
The Role Of Corticothalamic Feedback On The Response Dynamics Of Thalamic Neurons

Funding Amount

Summary
A fundamental question in neuroscience is how the brain selectively processes sensory information to generate a reliable representation of the world. Positioned in the centre of the brain, the thalamus plays a key role in sensory processing. This project investigates how the interaction between thalamus and cortex shapes the selection and gating of sensory information. This is a fundamental question in basic neuroscience with the potential to increase our knowledge about attentional deficits.
