5. Non-invasive brain stimulation proven to improve memoryScientists at Northwestern University have successfully used a non-invasive brain stimulation for the first time that can be used like a scalpel to make specific improvements in precise memory.
Precise memory, for example, is used to recall specific colors, shapes and locations of buildings, versus just knowing the name of the town that the building is located in. Scientists were able to improve the precision of patients’ memory for identifying locations by stimulating the area of the brain that holds spatial memory.
Using an MRI, scientists were able to determine where memory-related brain networks were located and stimulated them with non-invasive electromagnetic stimulation. The brain stimulation lasted 24 hours and correlated with brain activity changes.
Scientists used detailed memory tests to prove that spatial precision memory was improved and an EEG reading showed that brain network function was improved.
