大脑最早的自我表征能力是在进化过程中发现了协调和调节体内信号的神经网络解决方案，从而改善了行为策略。在组织连贯的行为选择方面，神经模型表现出了额外的灵活性，这些神经模型将大脑的一些内部状态表示为身体的状态，同时将其他信号表示为对外部世界的感知。大脑操纵内部模型来预测不同行为选择在外部世界中的不同后果。因此，自我并不是通过一个非物质的灵魂，而是通过物质大脑的一系列表征能力来识别的。
The brain's earliest self-representational capacities arose as evolution found neural network solutions for coordinating and regulating inner-body signals, thereby improving behavioral strategies. Additional flexibility in organizing coherent behavioral options emerges from neural models that represent some of the brain's inner states as states of its body, while representing other signals as perceptions of the external world. Brains manipulate inner models to predict the distinct consequences in the external world of distinct behavioral options. The self thus turns out to be identifiable not with a nonphysical, soul, but rather with a set of representational capacities of the physical brain.
