Galvanotactic control of the cells that responded to the cathode during the induction process. 25 Amoeba proteus (5 experimental replicates, 2–7 cells per replicate) that migrated towards the cathode during the induction process were again subjected to a controlled electric field (galvanotaxis during 30 min). All the amoebae migrated towards the cathode, confirming that these cells were unconditioned, and that their natural behavior was not altered by the induction process. “N” total number of cells, “Er” experimental replicates, “nr” number of cells per replicate, “t” galvanotaxis time, “ + ” anode, “−” cathode. Both the x and y axis show the distance in mm, and the initial location of each cell has been placed at the center of the diagram
