Figure 2. Data from parts II and III. The continuous curved line depicts the relation between cerebral metabolic rate for glucose (CMR sub G) and depolarization times as derived from the hypothermic data described in part I and was constructed by combining the polynomial equations that were fitted to the scattergrams in figures 1A and 1B. Filled diamonds - data points for the hypothermic animals ([nearly equal] 27 degrees Celsius) in parts II and III, with superimposed x and y standard deviations; open circles = data points for pentobarbital- anesthetized, normothermic rats; dashed crosses = x and y standard deviations; filled triangles - isoflurane animals (SD bars not shown for clarity).
