Playing video games tennis may enhance memory


first_imgActivities like playing video games or tennis may help enhance your memory, a study has found. Attention-grabbing experiences release memory-enhancing chemicals in brain, helping to store memories that occur just before or soon after the experience, the study mentioned.The study, published in the journal Nature explains at the molecular level why people tend to remember certain events in their lives with particular clarity as well as unrelated details surrounding those events.  Also Read – Add new books to your shelf“Activation of the locus coeruleus (part of the brainstem) increases our memory of events that happen at the time of activation and may also increase the recall of those memories at a later time,” said Robert Greene, Professor at the Peter O’Donnell Jr Brain Institute at UT Southwestern Medical Center’s Texas Institute for Brain Injury and Repair, at Dallas in Texas. The latest study established that dopamine in the brain can be naturally activated through behavioural actions and that these actions enhance memory retention. The study tested 120 mice to establish a link between locus coeruleus (LC) neurons and neuronal circuits of the hippocampus – the region of the brain responsible for recording memories – that receive dopamine from the LC. One part of the research involved putting the mice in an arena to search for food hidden in sand that changed location each day.  Also Read – Over 2 hours screen time daily will make your kids impulsiveThe study found that the mice that were given a chance to explore an unfamiliar floor surface 30 minutes after being trained to remember the food location did better in remembering where to find the food the next day. Researchers correlated this memory enhancement to a molecular process in the brain by injecting the mice with a genetically encoded light-sensitive activator called channelrhodopsin. They found that this activation could cause a direct, long-lasting synaptic strengthening – an enhancement of memory-relevant communication occurring at the junctions between neurons in the hippocampus.  This process can mediate improvement of learning and memory.last_img
