The transmission speed of a signal in anything, saline, water or vacuum is given by:

v=c?v

where?is therelative permittivity. Seethis articlefor a little more info, or Google for many related articles. I couldn't find a figure for saline, but the relative permittivity of water at STP is about 80 (at 1kHz), so that suggests the signal transmission speed in saline would be of orderc/80--vor about0.11c.

Thanks and regards
