Movie 3.

Head removal rescues loss of cathodic electrotaxis in head fragments. The response of head fragments to 2V is shown first, before and after polarity swap, followed by the response to 2V of the same individuals after decapitation and 1 day of healing, before and after polarity swap. The white bar represents the location of the cathode. Movie is sped up 8x.
