Improving Brain Mapping: A New Way to Handle Noisy EEG & MEG Data

Electroencephalography (EEG) and Magnetoencephalography (MEG) are really cool tools doctors and scientists use to study the brain. But they're not perfect. Sometimes, they give blurry pictures of the brain (low spatial resolution) and might miss some parts (partial brain coverage). Plus, some sensors can be noisy, making the data hard to read. This can mess up our understanding of brain activity. So, scientists have been trying to fix this issue. Recently, they came up with a new method using electromagnetic source imaging to fill in the missing pieces or clean up noisy data. This makes the brain maps clearer and more accurate. Have you ever tried to draw a picture with blurry vision or one hand tied behind your back? It's tough, right? That's kind of what scientists are dealing with when they use EEG and MEG. But with this new method, it's like they're getting a new pair of glasses and an extra hand to draw a better picture.
