Fig. 4. A typical result showing the reversibility of the effect of an applied
electric field (3 V cm-1) on the galvanotactic response of MAT-LyLu
cells. The graph shows the plot of the average cosine of directional segmental
angle ß calculated from 50 trajectories against time. The segment
corresponds to the distance covered by the cell in 10 minute intervals. The
field was reversed after 3 hours of recording, at the point marked by the
arrow. Positive values of ß corespond to cathodal movement of cells.
