A new study has revealed that playing tennis or video games may help in enhancing your memory to a certain extent. 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. “Activation of the locus coeruleus 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 Centre’s Texas Institute for Brain Injury and Repair, at Dallas in Texas. 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. Memory is the process in which information is encoded, stored, and retrieved. Encoding allows information from the outside world to be sensed in the form of chemical and physical stimuli. In the first stage the information must be changed so that it may be put into the encoding process. Storage is the second memory stage or process. This entails that information is maintained over short periods of time. Finally the third process is the retrieval of information that has been stored.
