本文提出了一个修改目前接受的观点体温的中枢神经整合。代替具有多个输入和输出的单个积分器，新模型包括与体温调节反应一样多的积分器。然而，这些整合剂被假定在神经系统的许多水平上都有代表性，每个水平都受到上面和下面水平的促进或抑制。如此复杂的布置的目的是实现对体温的越来越精细的控制。考虑到恒温性是如何进化的，最初与温度无关的反应逐渐受到温度的控制，这样的大脑组织是非常合理的。
This article proposes a modification of the currently accepted view of the central neural integration of body temperature. In place of a single integrator with multiple inputs and outputs, the new model includes as many integrators as there are thermoregulatory responses. Futhermore, these integrators are postulated to be represented at many levels of the nervous system, with each level facilitated or inhibited by levels above and below. The purpose of such a complicated arrangement is to achieve finer and finer control over body temperature. A consideration of how endothermy might have evolved, with originally nonthermally related responses gradually coming under thermal control, makes such a brain organization highly reasonable.
