It takes one-thousand of a second for a membrane to polarize and initiate an impulse of excitation. The ionic mechanism that governs this process is what makes life possible. It is what maintains all vital process and help us crate memories, it is in any active cells of the heart and the brain, it is a bioelectric potential. But what really makes this process remarkable is that bioelectricity propagates with an incredible speed, faster than the speed of light. Capturing and dissecting such dynamic processes is everything but trivial.

This white paper looks at capturing ultra-fast processes with high pressure freezing.
