Fig. 6. Reversibility of the effect of TTX on the galvanotactic behaviour of
MAT-LyLu cells in an electric field of 3 V cm-1. The experiments
started with the cells just treated with the toxin (5 µM) whereby the
average cosine of directional segmental angle ß (calculated from 50
trajectories) was near zero (i.e. there was little directionality in the
movement). The toxin was washed after 3 hours of recording (at the moment
indicated by the arrow), whereupon the directionality of response was
restored. Other details as in Fig.
5.
