Understanding how the brain uses sensory information to guide reaching and grasping movements. Reaching, grasping and manipulating objects are crucial aspects of our daily lives, which are performed so effortlessly that they tend to be taken for granted. We know however that these functions take a relatively long time to mature (think of a baby learning how to get an object), and that they can be impaired by brain lesions involving a region called the posterior parietal cortex. We also know that ....Understanding how the brain uses sensory information to guide reaching and grasping movements. Reaching, grasping and manipulating objects are crucial aspects of our daily lives, which are performed so effortlessly that they tend to be taken for granted. We know however that these functions take a relatively long time to mature (think of a baby learning how to get an object), and that they can be impaired by brain lesions involving a region called the posterior parietal cortex. We also know that this region has multiple subdivisions, but how exactly these interact in allowing the sensory information to guide arm and hand muscles is unknown. Discovering how this happens in terms of cellular interaction can have profound implications for the creation of new technologies such as artificial limbs and autonomous robots, and result in health benefits.Read moreRead less
Inhibitory control of retinal sensitivity. We will determine how the nerve cells that carry information from the eye to the brain are always able to provide signals despite very different environments; daylight, fog and night. Knowledge of how nerve cells achieve this rapid learning is important for any understanding of brain function; it is fundamental if we are to develop machines that see or that help restore vision in humans. The project will provide the world's first look at the synaptic ph ....Inhibitory control of retinal sensitivity. We will determine how the nerve cells that carry information from the eye to the brain are always able to provide signals despite very different environments; daylight, fog and night. Knowledge of how nerve cells achieve this rapid learning is important for any understanding of brain function; it is fundamental if we are to develop machines that see or that help restore vision in humans. The project will provide the world's first look at the synaptic physiology that underpins all visual perception, helping to bring Australia back to the forefront of research in this field. This new collaboration between two successful researchers will attract top quality students and researchers from Australia and abroad and be published in major journals.Read moreRead less
