Bioelectrical activity of isolated ventral nerve cords of the cockroach, Periplaneta americana L., treated with toxaphene.

Effects of toxaphene were studied with the ventral nerve cord (VNC) of the cockroach, Periplaneta americana (L). Intense forms of activity were observed in isolated nerve preparations treated with toxaphene. Latent periods between introduction of toxaphene and onset of intense activity decreased as the concentrations were increased.
