Summary
The essential steps in forming a normal functioning brain occur during life as an embryo. If these processes go haywire, there can be serious repercussions for life after birth. This project seeks to understand how the brain forms during embryonic stages so that better treatments and procedures can be developed to deal with developmental problems.

Summary
The olfactory (smell) system is a unique part of the nervous system; nerve cells are generated throughout life and it can regenerate even after injury. It therefore provides an excellent model for examining the growth, development and maintenance of nerve cells. This project will examine the effects on the organisation of the olfactory system when some guidance signals are altered. Information we obtain about how this system develops and regenerates may be useful in treating brain disorders and ....The olfactory (smell) system is a unique part of the nervous system; nerve cells are generated throughout life and it can regenerate even after injury. It therefore provides an excellent model for examining the growth, development and maintenance of nerve cells. This project will examine the effects on the organisation of the olfactory system when some guidance signals are altered. Information we obtain about how this system develops and regenerates may be useful in treating brain disorders and spinal injuries The results of these experiments will provide important information on the the initial growth and targeting of these nerve cells which may have implications for regeneration of these as well as other nerve cells.Read moreRead less

It therefore provides an excellent model for examining the growth, development and maintenance of nerve cells. This project will examine the effects on the organisation of the olfactory system when some guidance signals are altered. Information we obtain about how this system develops and regenerates may be useful in treating brain disorders and spinal injuries In the current project we will examine the effects of specific nerve cell guidance molecules by generating transgenic mice that produce these molecules only in the olfactory system. We can then determine what changes occur to the nerve cells when these extra molecules are produced. The results of these experiments will provide important information on the the initial growth and targeting of these nerve cells which may have implications for regeneration of these as well as other nerve cells.Read moreRead less
Growth factors are essential molecules for normal brain development. Variations in the amount of the different growth factors have been implicated in such diseases as AlzheimerÍs and ParkinsonÍs disease. This project will study the precursor of a growth factor known as brain derived neurotrophic factor (BDNF) and what specific roles the precursor might play in brain development.
Membrane Fusion In Axonal Regeneration: Molecules And Mechanisms

Summary
Limited nerve regeneration is the main obstacle for recovery from spinal cord and brain injuries. Understanding the cellular and molecular mechanisms underlying axonal regeneration is an essential step toward the development of novel effective therapies to enhance this process. In this proposal, we use the powerful molecular and genetic tools available for the small nematode worm C. elegans to identify and study axonal regeneration and discover the key molecules involved.

Summary
There are, at least, two major obstacles that have to be overcome in the design of therapies to assist the repair of injured brain tissue. First, the nerve cells that are damaged have to be encouraged to regrow - typically this regrowth is inhibited in the brain; and second, this regrowth has to be directed so that the correct connections are re-established. This project will begin to unravel some of the mechanisms that nerve cells use to wire up together during development. This information can ....There are, at least, two major obstacles that have to be overcome in the design of therapies to assist the repair of injured brain tissue.

This project will begin to unravel some of the mechanisms that nerve cells use to wire up together during development. This information can be used to assist in trying to modulate and facilitate directed regrowth following injury.Read moreRead less
