Nice #Labrigger post on a point that is easy to forget in #2p #CalciumImaging: Image quality is not just about seeing cells, but about photons/s/neuron.
Larger FOVs are tempting, but they usually mean fewer #photons per cell, lower sensitivity to small Delta F/F events, and more trouble w/ #neuropil contamination. In the end, fidelity is a measurement problem, not just an optics problem:

Quantum Networking Advances
Researchers have teleported a photon’s state between two separate quantum dots over a 270-meter open-air link aka the properties of one photon were transferred to another through quantum teleportation.
