How Memory Is Lost: Loss of Memory Due to Aging May Be Reversible
Yale researchers have released a study that has explained how memory works at a cell level. What it comes down to, in its simplest terms, is how quickly neurons in the brain respond. While the researchers found that the older animals they were testing had slower neuron responses, they also found that they could rebalance the chemicals in the brain to speed up the neurons, restoring cognitive ability. This research has great importance to the aging population. "Age-related cognitive deficits can have a serious impact on our lives in the Information Age as people often need higher cognitive functions to meet even basic needs, such as paying bills or accessing medical care," said Amy Arnsten, Professor of Neurobiology and Psychology and a member of the Kavli Institute for Neuroscience.
