Pathways To Vision Following Lesions Of The Primary Visual Cortex

$2,500,000.00
Summary
Lesions due to stroke or trauma in the occipital lobe cause blindness, which can be complete or restricted to part of the visual field. My work has identified areas of the visual brain that remain active after such lesions. I want to find out if these areas can be used to partially restore vision. This project will study the potential roles of different surviving areas, how brain cells rewire their connections in response to damage, and how rehabilitation programs work at the cellular level.
The Claustrum Enigma: Unlocking The Role Of The Last Unknown Area Of The Primate Brain

Summary
Despite nearly 200 years of study, the function of the claustrum remains unclear. Interest in this brain structure has recently been revived by findings showing damage to the claustrum in several major diseases, and by the suggestion that the claustrum may have a role in consciousness. Here we propose a series of experiments to test the novel hypothesis that the claustrum is part of the default mode network, a group of brain areas that act together when we aren't thinking about anything in parti ....Despite nearly 200 years of study, the function of the claustrum remains unclear. Interest in this brain structure has recently been revived by findings showing damage to the claustrum in several major diseases, and by the suggestion that the claustrum may have a role in consciousness. Here we propose a series of experiments to test the novel hypothesis that the claustrum is part of the default mode network, a group of brain areas that act together when we aren't thinking about anything in particular, that is- most of the time.Read moreRead less
Characterisation Of MiRNAs That Regulate Vascular Leakage.

Summary
Vascular permeability or leak is a major problem in diseases such as cancer and in cardiovascular diseases . MicroRNAs (miRNAs) are small control genes that influence dveleopment and disease. We have identified a miRNA cluster in endothelial cells, the cells that line the blood vessels, that is important in the control of vascular leak. This project is focused on understanding the impact of these miRNAs in disease.
Role Of Epigenomic Changes In Conferring Hyperglycemic Memory

Summary
The major burden of type I diabetes remains its vascular complications including diabetes-accelerated athersclerosis. Despite improved glucose control, diabetic individuals develop complications as a result of prior poor glycemic control. Although the development and progression of these diabetic complications is strongly associated with mean levels of glucose, recent studies suggest that the deleterious effects of early exposure to high levels of glucose persist for years even after treatment h ....The major burden of type I diabetes remains its vascular complications including diabetes-accelerated athersclerosis. Despite improved glucose control, diabetic individuals develop complications as a result of prior poor glycemic control. Although the development and progression of these diabetic complications is strongly associated with mean levels of glucose, recent studies suggest that the deleterious effects of early exposure to high levels of glucose persist for years even after treatment has returned glucose levels towards normal.Read moreRead less
A 3D Cross-Modality Atlas Of The Human Brainstem For Scientists And Clinicians

Funding Amount
$363,455.00
Summary
Recent technical advances dramatically improved imaging of the human brainstem. However, there are limited frameworks for interpreting the images. The project will address this by acquiring high quality MRI anatomical and MR microscopy data from postmortem brains and registering these with structures in Atlas of the Human Brainstem (Paxinos and Huang, 1995) where almost 500 brain areas are delineated. Our work will assist with the diagnosis of brain disorders and facilitate clinical research.
