The long-time Marine Biological Laboratory scientist was known for using his own hand-built microscopes to image the dynamics of live cells.

Researchers are developing a variety of approaches for clearing neural tissue to get a better view of the brain’s circuitry.

Scientists traced 1,000 neurons through the mouse brain, uncovering new details about how the organ is wired.

Only recently have scientists directly witnessed this most pivotal of events in biology, thanks to new technology that allows them to observe the process in living cells. It’s teaching them a lot.

A newly developed imaging technology visualizes entire mouse brains in two and three dimensions using multicolor fluorescence microscopy.

After a severe case of flu, mice have chemosensory cells in their lungs, a place where they don’t normally occur.
