There are many important details about consciousness that this figure sketches in, like the role of Cartesian versus relational thought and the important role of memory for consciousness and perception. Memory is our lifetime of objects related to the experience of the moment. However, this assumes that cognition works somehow and jumps right into feeling and consciousness. This figure also does not include the very important roles of emotion and the primitive mind in feeling and choice of action.
Our brains exchange matter with the objects in the world that we perceive and while the typical matter that we exchange is made up of photons of light (i.e. visual images), sensation can also be sound, taste, touch, or smell as well. Don't forget that our body shines on the same object whose light then shines on us as well. The EEG spectra (see also) of the brain show the amplitudes of neural recursion waves associated with thought according to the various states of the mind. The EEG amplitudes are the relational waves of recursions of electrical activity among neurons present in our brains.
