In a world first, scientists from the University of Sussex have recorded blood oxygen levels in the hippocampus and provided experimental proof for why the area, commonly referred to as ‘the brain’s memory centre’, is vulnerable to damage and degeneration, a precursor to Alzheimer’s disease.
To understand why this region is so sensitive, the University of Sussex researchers, headed up by Dr Catherine Hall from the School of Psychology and Sussex Neuroscience, studied brain activity and blood flow in the hippocampus of mice. The researchers then used simulations to predict that the amount of oxygen supplied to hippocampal neurons furthest from blood vessels is only just enough for the cells to keep working normally.
Dr Catherine Hall, Senior Lecturer in Psychology at the University of Sussex says:
“These findings are an important step in the search for preventative measures and…
