Mind Aglow: Scientists Watch Thoughts Form in the Brain

When a single neuron fires, it is an isolated chemical blip. When many fire together, they form a thought. How the brain bridges the gap between these two tiers of neural activity remains a great mystery, but a new kind of technology is edging us closer to solving it. The glowing splash of cyan in the photo above comes from a type of biosensor that can detect the release of very small amounts of neurotransmitters, the signaling molecules that brain cells use to communicate. These sensors, called CNiFERs (pronounced “sniffers”), for cell-based neurotransmitter fluorescent engineered reporters, are enabling scientists to examine the brain in action and up close. This newfound ability, developed as part of the White House BRAIN Initiative, could further our understanding of how brain function arises from…
