MECHANISMS OF RETINULA CELLS 629 through which an appreciable fraction of the current associated with the generator potential may flow. Consider that solitary retinula cells do not occur in insects or Limulus, and that rhabdomeres, almost without exception (, see Fig. 6, right), occur at cell boundaries inside the retinula. According to the hypothesis, a solitary retinula cell (Fig. 5, left) undergoing depolarization might be expected to suffer current "leakage" through rhabdomere membrane. It is conceivable th

Consider that solitary retinula cells do not occur in insects or Limulus, and that rhabdomeres, almost without exception (, see Fig. 6, right), occur at cell boundaries inside the retinula. According to the hypothesis, a solitary retinula cell (Fig. 5, left) undergoing depolarization might be expected to suffer current "leakage" through rhabdomere membrane. It is conceivable that the retinula-type organization (Fig. 5, center) is advantageous because, with rhabdomere facing rhabdomere, current flowing inward through distal, non- rhabdomere membrane is conserved for outward, excitatory flow through mem- brane of the retinula cell axons.
