Whole cell recordings with blocked action potentials.

In whole cell electrophysiology experiments, we include this in our internal solution to block voltage gated sodium channels. Typically, we use 5-30 mM. Blockade is use-dependent. Drug needs some time and activity to be more effective. Picture is of a putative evoked EPSC in a cell held at +40mV with Qx-314 in internal solution.
