Story summary

Researchers at MIT's Picower Institute for Learning and Memory report that theta-frequency brain waves (3–6 Hz) are crucial for visual working memory.
The waves sweep across the cortex like radar to help detect visual changes.
Non-human primates played a video game identifying color changes in squares, with performance tied to theta phase and vertical position.
The team aims to amplify specific brainwave frequencies to enhance visual memory capacity.
