When the neuron gets a cue, gates on sodium channels are thrown open, ions rush in, and the voltage surges.

When bulky amino acids are introduced at these positions, the channel width no longer corresponds to the size of sodium ions, and instead cesium ions are transported.

When researchers talk about channel selectivity, they're referring to the ability of peptides or small molecules to turn off only one particular sodium channel.

When appropriately stimulated, the channels open, sodium ions flow in, and the muscle cells contract.

When nerve cells receive a signal of pain or other sensation, the signal opens sodium channels and floods the cell with positively charged sodium ions, which positively charge the neurons until the electrochemistry changes enough to inactivate the channels and close them.

Zheng, being a membrane protein rookie, had what he calls a stroke of beginners luck when he and his team solved the structure for a voltage-gated sodium channel, a channel others in the field had long been working to solve.
