Rhythmically stimulating the brain with electrical currents could boost cognitive function, according to analysis of over 100 studies

Figuring out how to enhance a person’s mental capabilities has been of considerable interest to psychology and neuroscience researchers like me for decades. From improving attention in high-stakes environments, like air traffic management, to reviving memory in people with dementia, the ability to improve cognitive function can have far-reaching consequences. New research suggests that brain stimulation could help achieve the goal of boosting mental function. In the Reinhart Lab at Boston University, my colleagues and I have been examining the effects of an emerging brain stimulation technolog...
