Researchers at Johns Hopkins Medicine say they have used a "zap-and-freeze" technology to watch hard-to-see brain cell communications in living brain tissue from mice and humans. Findings from the new ...

Researchers have come up with a clever new way of freezing brain cells just as they fire out a signal, meaning processes that normally happen too quickly to observe can be studied in detail – and ...

A new bioluminescent tool allows neurons to glow on their own, letting scientists track brain activity without harmful lasers or fading signals. The advance makes it possible to watch individual brain ...
