Figure 4.4: Homeostatic regulation of a bodily function, for example blood sugar levels over time. In the illustration shown on the upper part of the figure, blood sugar is maintained at an average level that is within a normal range. A disturbance in blood sugar level, in this case a decrease as shown in red, leads to corrective mechanisms that return blood sugar levels back to the normal range. This pattern of response reflects homeostatic regulation. In contrast, the pattern of response shown in the lower part of the figure is not characteristic of homeostatic regulation. In this second case, for example, a decrease in blood sugar levels leads to a rebound increase over and above normal levels in an active attempt to ‘compensate’ for the amount by which it was previously reduced. Since the pattern of recovery sleep observed after sleep deprivation is largely as shown on the bottom section of this figure then it does not conform to the principle of homeostatic regulation, and therefore reflects a different process.
