Neurosteroids are known as allosteric modulators of the ligand-gated ion channel superfamily. Voltage-gated sodium channels (Nav) play an important role in mediating excitotoxic damages. Here we report the effects of neurosteroids on the function of Nav, using voltage-clamp techniques in Xenopus ooc...
