This chapter focuses on hierarchical circuits in the brain that might make higher levels of objectivity associated with an emergent self possible, with particular emphasis on concepts as feature extraction. An animal with an encephalization quotient (EQ) above 1 has higher relative brain weight than an average animal of its body weight. This extra brain matter may be available for functions beyond mere physiological control. Also, as brains become larger in absolute size, an increasing percentage of the neurons appear to be dedicated to higher functions. This chapter describes an arrangement of brain circuits that allows one set of neurons to abstract qualities from responses in another set of neurons. In particular, the chapter discusses brain modularity, visual circuits, visual processing in the brain, how higher derivatives of information are made in frontal areas of the brain, how neurons convey information between different forebrain areas, and neuron counts in the cerebellum. Finally, it considers the correlation between genes and brain size.
