This is not meant to diminish the profound importance of rational thought in human affairs, but a question of great import is whether our cognitions wag the emotional tail more than the emotional tail wags the cognitions.
Considering the fact that emotional feelings are so important in guiding cognitive and social decision making, one must certainly suspect that the existence of cool rationality in the human mind can be exaggerated. There is a primitive affective awareness built into the infrastructure of the brains that is the birthright of every mammal, every bird, and surely many other species of animal as well. If that could be achieved without marginalizing the best of cognitive and cultural achievements, it could be a beneficial lesson for each of the local tribes as well as the human race. The culture eventually understands the foundations of human and animal nature, and recognizes that one is the inheritor of the core emotional-affective systems that are remarkably similar to those of other mammals. They are not by themselves accessible to experience, as may be the macroscopic states initiated by global state transitions. The prediction is made for clinical testing that wave packets are precursor to states of awareness. They induce the formation of macroscopic patterns that coalesce like scintillating pools over much and perhaps all of each hemisphere. The wave packets from all sensory areas are broadly transmitted through the forebrain. The AM patterns correlate not with features but with the context and value of sensory stimuli for the subjects, in a word, their meaning. The condensation disks sustain 2D spatial patterns of phase and amplitude of carrier waves in the beta and gamma EEG. The sensory-driven action potentials condense into mesoscopic wave packets like molecules forming raindrops from vapor. They form when sensory input destabilizes the primary receiving areas by local state transitions. Mesoscopic activity bridges the gap by the formation of wave packets. Macroscopic activity of the whole forebrain expressed by behavior is perceptual.
Microscopic activity expressed by action potentials is sensory. Three levels of brain function are hypothesized to mediate transition from sensation and perception. The driven activity induces hemisphere-wide, self-organized patterns of neural activity called wave packets. Stimulus-activated receptors drive cortical neurons directly (olfactory) or indirectly through thalamocortical relays. Sensing and perceiving involve enormous numbers of widely distributed dendritic and action potentials in cortex, before, during and after stimulus arrival but with differing spatiotemporal patterns.
