Summary
Specific genetic mutations can lead to widespread changes in the body. Here we are looking at congenital Hereditary and Sensory Autonomic Neuropathy type III (HSAN III). Affected individuals have difficulty walking, which progressively worsens over time. This series of experiments aims to increase our understanding of the underlying neurophysiological disturbances in HSAN III.

Summary
Detection of important sounds within a noisy background is a crucial function of the mammalian hearing system and defects in this function impair social interaction, learning and development. In addition, activity in the brain needs to be carefully regulated by intrinsic circuitry in order to prevent excessive activity responsible for conditions such as tinnitus. The mechanisms by which the brain achieves this are poorly understood and this project aims to improve our understanding of some of th ....Detection of important sounds within a noisy background is a crucial function of the mammalian hearing system and defects in this function impair social interaction, learning and development.

Understanding The Organisation Of The Medial Parietal Cortex: Sensorimotor Integration For Goal-directed Behaviour

Summary
Reaching and grasping are of obvious significance for a productive life, and many of the brain areas known to be involved in the direction of arm movements are located in the parietal lobe. Stroke affecting this part of the brain causes disability, as people become unable to reach accurately, or to close their hands around objects with appropriate strength. This project will combine modern physiological and anatomical methods to reveal the brain circuitry responsible for such crucial skills.
The Vestibulo-collic Reflex In Humans And Its Use In Diagnosis Of Vertigo

Funding Amount

Summary
This project will investigate the vestibulo-collic reflex (VCR): a head-stabilising reflex of the neck muscles. The VCR plays an important role in human balance, but is not well-understood. A form of the reflex is used to test vestibular (balance) function in patients with dizziness and vertigo, however the accuracy and interpretation of the test as it is currently used is not optimal. This project aims to improve the accuracy of the VCR in the diagnosis of balance disorders.
While there has been recent excitement about possible treatments for the symptoms of Autism, advances in understanding the underlying neuroscience of abnormal brain function that underlies autistic tendency are still painfully slow. This application aims to establish fully a physiological mechanism for altered autistic perception, to see if it can be applied to early diagnosis in infants and young children and to establish whether in such plastic young brains it is possible to guide perceptual l ....While there has been recent excitement about possible treatments for the symptoms of Autism, advances in understanding the underlying neuroscience of abnormal brain function that underlies autistic tendency are still painfully slow. This application aims to establish fully a physiological mechanism for altered autistic perception, to see if it can be applied to early diagnosis in infants and young children and to establish whether in such plastic young brains it is possible to guide perceptual learning to permanent improvement.Read moreRead less
