Scientists reverse memory decline using electrical pulses

"The study focused on a part of cognition called working memory, the brain system that holds information for short periods while we are making decisions or performing calculations. Working memory is crucial for a wide variety of tasks, such as recognizing faces, doing arithmetic and navigating a new environment. Working memory is known to steadily decline with age, even in the absence of any form of dementia. One factor in this decline is thought to be a disconnection between two brain networks, known as the prefrontal and temporal regions. In young people, the electrical brain activity in these two regions tends to be rhythmically synchronized, which scientists think allows information to be exchanged between the two brain areas. However, in older people the activity tends to be less tightly synchronized. This may be as result of deterioration of the long-range nerve connections that link up the different parts of the brain."
