Could the time we spend on computers indicate our likelihood of developing Alzheimer’s?

Scientists at Oregon Health and Science University have just completed the first part of a study which indicates that the amount of time we use our home computers may help scientists to detect signs of Alzheimer’s disease before the patients exhibit any symptoms of cognitive decline. The study, which is scheduled for publication in a future edition of the Journal ...

The Reason Why We Remember Some Events, Places and Things More Easily Than Others


Have you ever wondered why we’re able to remember some things more easily than others? If so, you’ll be interested in the latest research from the Center for Neuroscience at the University of California, which concludes that our brains are able to prioritise rewarding memories over other kinds of memories, and that they reinforce these particular memories by replaying them ...

New Drug has Been Shown to Prevent Age-Related Brain Changes in Rats


Researchers at the University of California have released a new study in The Journal of Neuroscience which gives an insight into the mechanisms of cognitive decline, and also identifies potential strategies to reverse it. Using lab rats, the scientists were able to reverse the process where aged brain cells lose the fibres that are responsible for receiving neural impulses, a ...

Suffering From anxiety and chronic stress may increase the risk of developing Alzheimer’s


New research suggests that you may be at an increased risk of developing depression and neurological diseases, such as Alzheimer’s, if you suffer from anxiety or chronic stress. Scientists from the Rotman Research Institute used laboratory animals and already published human studies to examine the areas of the brain which are impacted by long-term anxiety, fear and stress. They then ...

Our ability to remember things is greater than we thought


Researchers at the Salk Institute for Biological Studies now think that we have up to ten times more capacity for creating memories than was originally thought. By studying the size of neural connections, they’ve been able to answer longstanding questions about the energy efficiency of the brain, offering engineers insight which could help them to build computers which are both ...

Scientists Give Us An Excuse to Play 3-D Video Games

3-D video game

According to neurobiologists at the University of California, Irvine, playing three dimensional video games can enable us to make memories more easily. While it’s already known that playing 3-D video games can improve both eye-to-hand coordination and reaction times, this new finding offers a novel way to help those individuals who suffer from dementia or other memory problems. The study ...

Scientists Discover a New Molecular Mechanism That Causes the Loss of Synapses in the Brain


Even before Alzheimer’s sufferers show symptoms of the disease, changes are taking place in their brain, and while scientists are yet to find the causes of this disease, they’ve recently discovered more about how the synapses are lost in the early stages. This recent study was conducted by scientists at the University of New South Wales in Australia, with their ...

How Does Your Brain Make and Store Memories?


We all have memories; but how does our brain actually make and store memories? The difference between long-term and short-term memory. We’ve all heard the terms long-term and short-term memory. Short-term memory is used to refer to our recollection of things that have happened recently and, while we may think that this covers a period of say the last hour, ...
