Non-invasive brain stimulation proven to improve memory

Scientists 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.

“We show that it is possible to target the portion of the brain responsible for this type of memory and to improve it,” said Joel Voss, lead author on the study and assistant professor of medical social sciences at Northwestern University. “People with brain injuries have problems with precise memory as do individuals with dementia, and so our findings could be useful in developing new treatments for these conditions.”
