Here we show that the Olympus SZX stereo and upright BX microscopes, both with fluorescence illumination capabilities, are perfect for use in these situations. For decades the chicken embryo has ...

Axons can be shaped like strings of pearls, research in mice and people show. How that shape may influence brain signaling is not yet clear.

A new study may overturn the century-old understanding of how neurons are shaped—but not everyone is on board.

"The reason people have missed this axon morphology before, and that we were able to observe this, is because we are looking at cryo-preserved tissues under an electron microscope," Watanabe said.
