In the future, interventions to train specific areas of the brain to be more efficient may enable normal aging adults to enhance memory and other cognitive functions. According to a study by Massachusetts General Hospital, ‘Superagers’ who performed a challenging memory task in an MRI scanner were able to learn and recall new information as well as 25-year-old participants. Neurons in the visual cortex of brains of superaging older adults retain their selective and efficient ability to process visual stimuli and create a distinct memory of the images.
