Summary
Epileptic seizures in the brain are often focal. If anti-epileptic drugs are ineffective, a deep brain stimulator may be implanted to abort seizures at their onset or the seizure tissue may be removed. This project aims to locate the seizure tissue from non-invasive EEG-MEG recordings of seizure-like brain activity using a realistic computer model of the electromagnetic fields in the brain. Knowing the location more exactly will improve the outcomes of deep brain stimulation and removal surgery.

Summary
The recent application of novel techniques to evaluate gastrointestinal motor function has established that the rate which the stomach empties food is abnormally slow in ~50% of people who have insulin-dependent (type 1) or non-insulin dependent (type 2) diabetes. Delayed stomach emptying was thought to be an infrequent complication in diabetes; much less common than damage to the eyes, kidneys or nerves. Abnormal stomach emptying may contribute to a number of problems in diabetes, including sym ....The recent application of novel techniques to evaluate gastrointestinal motor function has established that the rate which the stomach empties food is abnormally slow in ~50% of people who have insulin-dependent (type 1) or non-insulin dependent (type 2) diabetes. Delayed stomach emptying was thought to be an infrequent complication in diabetes; much less common than damage to the eyes, kidneys or nerves. Abnormal stomach emptying may contribute to a number of problems in diabetes, including symptoms such as nausea and bloating, and poor control of blood glucose concentrations. It is now recognised that the blood glucose level itself has a reversible effect on both stomach contractions and symptoms. For example, when the blood glucose is abnormally high (hyperglycaemia), the rate at which the stomach empties food into the intestine is slower and symptoms, such as fullness, are greater. The rate of stomach emptying and the absorption of glucose from the intestine affect the rise in the blood glucose level after a meal; this is an important issue because it is desirable to maintain blood glucose levels within the normal range to minimise the risk of both the development and progression of the complications of diabetes. In many people with diabetes eating a meal results in a substantial fall in blood pressure, which may cause fainting and falls. By slowing gastric emptying the magnitude of the fall in blood pressure is minimised. Our group has been the recipient of ongoing support from the NH and MRC for approximately 18 years to conduct research in this area. As a result we have performed the most comprehensive studies to date and developed new methods to evaluate stomach and intestinal function in people with diabetes, resulting in international recognition. The studies proposed in the current application represent a logical development from our previous work and have important implications for the management of diabetes.Read moreRead less

The recent application of novel techniques to evaluate gastrointestinal motor function has established that the rate of which the stomach empties food is slow in up to 50% of people who have insulin-dependent (type 1) or non-insulin dependent (type 2) diabetes.

Delayed stomach emptying was thought to be an infrequent complication in diabetes; much less common than damage to the eyes, kidneys or nerves. It is now recognised that disordered stomach emptying may contribute to a number of problems in diabetes, e.g. symptoms such as nausea and bloating and poor control of blood glucose concentrations. In some people symptoms are disabling and affect quality of life adversely. The effects of stomach emptying on blood glucose control is likely to be important, as it is desirable to maintain blood glucose levels within the normal range to minimise the risk of both the development and progression of complications of diabetes. In many people with diabetes, particularly older people with type 2 diabetes, there is a fall in blood pressure after a meal which may result in fainting and falls. The magnitude of the fall in blood pressure is determined by the rate at which the stomach empties; faster emptying results in a greater fall in blood pressure. In the past both slow stomach emptying and symptoms were assumed to result from irreversible nerve damage, however it is now recognised that the blood glucose level itself has a reversible effect on both stomach contractions and symptoms. Our group has been the recipient of ongoing support from the NH and MRC for approximately 15 years to conduct research in this area. As a result we have performed the most comprehensive studies to date and developed new methods to evaluate stomach function in people with diabetes, resulting in international recognition.
