Summary
This study tests the effectiveness and safety of a potential new treatment for depression, which involves mild stimulation of the brain, given through pads placed on the scalp. There is no anaesthetic or seizure and the treatment is painless. The treatment is given on an outpatient basis, three times per week, for 10 sessions, each session taking approximately half an hour. If found to be effective and safe, this new treatment could be an alternative to antidepressant medication.

Summary
The human cerebral cortex is the pinnacle of evolution. It is the most complex structure known, responsible for all of those skills - like language and reasoning - that make our species so remarkable. It is also a major site of many brain diseases, like schizophrenia and epilepsy. An understanding of how the cerebral cortex works would be a remarkable achievement, of immeasurable benefit to human health. How can one go about studying such a complex structure?

It is the most complex structure known, responsible for all of those skills - like language and reasoning - that make our species so remarkable. It is also a major site of many brain diseases, like schizophrenia and epilepsy. An understanding of how the cerebral cortex works would be a remarkable achievement, of immeasurable benefit to human health. How can one go about studying such a complex structure? The strategy taken in this project is to begin by studying one of the simplest regions of the cerebral cortex, the olfactory (or piriform) cortex. The olfactory cortex is an evolutionarily ancient region of cortex, with a simpler architecture than other cortical regions. Its task is to process the sense of smell, a primitive sense that is more elaborated in lower animals than in humans. The broad goal of our research is to understand, by studying the olfactory cortex of rats, how olfactory processing occurs at the level of nerve cells (neurons). We will use a number of powerful techniques - including microelectrode recording and laser microscopy - to measure the electrical properties of individual neurons. We will also study the synaptic connections between neurons, and how these connections change following memory-inducing stimuli. It is hoped that this work will shed light on how the healthy cortex is able to process and store information, and how brain diseases cause these functions to deteriorate.Read moreRead less
Neurexin And Neuroligin: A Code For Synaptic Development

Summary
As soon as we are born, we interpret our world through our senses, learn new information and lay down memory. These processes require molecules that connect neurons together. Mutations in genes encoding these molecules result in incorrect wiring of the brain and lead to mental disorders such as autism and schizophrenia. Using simple insect models, our project aims to unravel the fundamental mechanisms of how these molecules function in the brain and how their interaction controls behaviour.
IDENTIFICATION AND FUNCTION OF RECEPTORS ON SYMPATHETIC TERMINAL SCHWANN CELLS

Summary
The terminals of sympathetic nerves control many of the internal organs. Pharmacological intervention to promote or antagonize the effects of these terminals is very important in a number of different disease states of the autonomic nervous system. The present research proposal sets out to determine the way in which glial cells that partly envelop these terminals control their capacity to function.
Sulfonadyn-based Dynamin I-specific Inhibitors And Epilepsy

Summary
Epilepsy affects 1% of people, yet 30% do not respond to anti-epileptic drugs (AEDs). Traditional drug discovery fails to improve this situation. Our team discovered dynamin as a new target for better AED design and our lead sulphonadyns reduces seizures in animals. We will design better sulfonadyns that can ultimately be used for clinical trials by designing the drugs away from its actions outside of neurons. If successful, this will accelerate new AED development with less side-effects.
