During the five psychosexual stages, which are the oral, anal, phallic, latent, and genital stages, the erogenous zone associated with each stage serves as a source of pleasure. Consciousness is a property of objects very different from simple properties such as consisting of atoms and molecules, or even firings of neurons; thus, all of hypotheses 2-9 face the problem of figuring out how consciousness became a property of wholes when it is not a property of their parts or a simple aggregate of the properties of their parts.

She was very fond of me, and would walk to our house every day to meet me. Stanislas Dehaene thinks that emergence comes from the broadcast of information across brain areas, whereas I argue in my new book Brain-Mind that the key properties are patterns of firing of neurons, binding of these patterns into more complex patterns, and competition among the resulting patterns. Only after about 29 weeks are the connections between these areas properly laid out, and it takes another month or so before the thalamus and the rest of the cortex are effectively communicating, as revealed by brain waves.
