Non-invasive brain stimulation using an applied magnetic field can strengthen brain connections that weaken as we age.
Perth researchers hope to use this technique to improve the quality of life and reduce the risk of falls and injuries in older people.
Past the age of about 60, there’s a weakening of the structural connections between the three different areas of the brain that control our decision-making processes, our ‘planning’ centres, and our fine-motor control.
It’s the connections between those areas that ultimately allow us to successfully interact with our environment, for example adjusting our foot placement when we step on uneven paving.
How do the power plants of the cell—the mitochondria—use their defence mechanisms to fight diseases such as Parkinson’s disease? This debilitating disorder is caused by an accumulation of proteins that have folded incorrectly.
The misfolded proteins then clump together and form sticky, cell-damaging deposits called plaques.
“We know that mitochondria are at the centre of the aging process,” says Prof Nick Hoogenraad, executive director of the La Trobe Institute for Molecular Science (LIMS). Nick and his team have found a mechanism mitochondria use to remove the plaques that are prone to form as we age.
