Rhythmic Electrical Brain Stimulation Improves Memory in Elderly People

On Monday, Neuroscientists at Boston University published a new approach to improve memory in elderly people. “This is an entirely different approach,” Robert Reinhart, who led the study, said in a press conference announcing the findings. The method uses specific frequencies of weak electrical current applied to the scalp at appropriate spots to target brain circuits…

Brainwaves Reveal IQ

What intelligence is and how to measure it are thorny questions.  If the brain’s information processing power could be measured directly with medical instruments, then the problematic assumptions, cultural biases, and pitfalls of IQ tests could be avoided. Moreover, direct measurement of the brain’s information processing power could reveal how specific brain circuits boost intelligence…
