Researchers have developed an endoscope as thin as a human hair that can image the activity of neurons in the brains of living mice. Because it is so thin, the endoscope can reach deep into the brain, giving researchers access to areas that cannot be seen with microscopes or other types of endoscopes.
“In addition to being used in animal studies to help us understand how the brain works, this new endoscope might one day be useful for certain applications in people,” said Shay Ohayon, who developed the device as a postdoctoral researcher in James DiCarlo’s lab at the Massachusetts Institute of Technology. “It could offer a smaller, and thus more comfortable, instrument for imaging within the nasal cavity, for example.”
