As water temperature is raised from just above freezing to 30C30^{\circ} \mathrm{C}30C, the solubility of oxygen decreases by about half. The b-wave is generated by a combination of ON- and OFF-type bipolar cells. In addition, the multifocal ERG (discussed below) can be used to assess macular function. The middle panel of traces shows ring averages. These are average mfERG traces within rings of different eccentricity. This will aid in preparing for down range mitigation operations as well as establishing Hot, Warm, and Cold Zones. Thus, the N95 component is likely generated by action potentials from RGCs.
