• Function
  • Presumably an on-bipolar (due to stratification) so depolarizes to light
  • Karschin and Wassle (1990): "Light responses typically consist of graded and sustained potential changes of 20-25 mV from an average dark potential between -50 and -30 mV, without the occurrence of repeititive action potentials."

  Cat Bipolar cb4 (wab, CBb3, not, ?)

  • Kolb et al '81 named it cb4
  • McGuire et al '84 equated cb4 to their CBb3 and to Famiglietti '81s wab)
  • Cohen and Sterling '90 did not find this cell in their tissue
