High-pressure freezing can be combined with optogenetics (‘flash-and-freeze’) or electrical field stimulation (‘zap-and-freeze’) to close this gap. In these methods, neurons are stimulated then frozen ...

Recent years have seen an upsurge of brain imaging, with renewed interest in techniques like electron microscopy, ... uses jets of liquid nitrogen to "snap-freeze" brain tissue down to -90oC, ...

Imagine owning a camera so powerful it can take freeze-frame photographs of a moving electron—an object traveling so fast it could circle the Earth many times in a matter of a second.

An alternative method, called cryo-electron tomography (cryo-ET), provides clearer images of the brain's smallest parts in a more native state, however, it requires freezing.
