Btx depolarizes the membrane and prevents repolarization. what effect would this have on electrical signaling by the nervous system?

BTX or batrachotoxin is a type of steroidal alkaloid which was first derived from the skin of Dendrobatidae or poison dart frogs. This neurotoxin prevents the muscle and nerve cells from transmitting electrical signals. The toxin permanently blocks electrical signal transmission from the nerves to the muscle by binding and inactivating the sodium channels.  

In the Expanded Academic ASAP, if choosing the peer reviewed articles, it would indicate that c. the articles one can see would contain information that was evaluated and verified as well by the experts in a field. Hope this helps.
