Brain cap gives scientists a better look at brain behavior
No, it's not a swimming cap, but it is making a splash in the field of brain science. This electroencephalography—or EEG—cap monitors electrical activity in the brain and has been helping scientists at Johns Hopkins understand what we pay attention to—and what we ignore.
"When we perform these tests, we present a test subject with visual stimuli, and then we create a time-locked image of what is happening in the brain at the exact same time," says Corbin Cunningham, a pre-doctoral fellow at the Science of Learning Institute at Johns Hopkins. "It's a very versatile tool. The work I do is mostly visual, but many people use the EEG to understand the role of emotion, or surprise, or auditory distractions."
