Brain conscious thought

Finally, there is consciousness, thought of as a by-product or property of the human brain, and psychology is the science for studying it. The forces affecting consciousness are not shown because, in terms of the physicalistic philosophy, social or psychological forces are derivative, not the "real" forces that actually control the universe. 

Spinal nerve— A nerve fiber that rises from the spinal cord instead of directly from the brain. Spinal nerves control muscle movement without conscious thought from an individual. 

Before we can understand how the neurotoxic venoms work, it is essential to understand how a nervous impulse is formed and transmitted. For this 1 will use a specific example, wiggling the big toe. If you want to move your big toe, you first think that you would like to do so (this might not be a conscious thought). This occurs in the frontal region of the brain. This message of desire is passed to the region of the brain which controls movement (the Motor Cortex in the Central Sulcus) where an impulse is generated. The impulse passes from the Motor Cortex, via the spinal cord, to peripheral nerves in the leg and eventually to the toe. The toe then moves. This whole process occurs within a second. 

Each sensory afferent neuron connects with an interneuron or accessory neuron. These interneurons are located entirely within the CNS, with the majority occurring in the cerebral cortex. They form numerous interconnections and are the means by which all cognitive information, thoughts and feelings, are processed. It should be emphasised that the main role of this processing of information is inhibitory. The sensory receptors provide the CNS with a massive amount of data. The interneurons process and filter this into a limited amount of useful and important informa tion. Conscious information processing forms just one part of this activity. A great deal of brain activity is concerned with routine processes, which continue without conscious awareness. 

The highest level of complexity is that expressed in that highest form of matter, living matter, life, which itself culminates in the brain, the plasticity of the neural system, epigenesis, consciousness and thought. 

If our thoughts and consciousness do not depend on the actual substances in our brains but rather on the structures, patterns, and relationships between parts, then Turbings could think. If you could make a copy of your brain with the same structure but using different materials, the copy would think it was you. 

The central point within our consciousness, our "spirit" in the hermetic sense, can now be seen as an entity that can work to control quantum probabilities. To our "spirits" our brain is a quantum sea providing a rich realm in which it can incarnate and manifest patterns down into the electrical/chemical impulses of the nervous system. (It has been calculated that the number of interconnections existing in our brains far exceeds the number of atoms in the whole universe - so in this sense the microcosm truly mirrors the macrocosm ). Our "spirit" can through quantum borrowing momentarily press a certain order into this sea and this manifests as a thought, emotion, etc. Such an ordered state can only exist momentarily, before our spirit or point of consciousness is forced to jump and move to other regions of the brain, where at that moment the pattern of probability waves for the particles in these nerve cells, can reflect the form that our spirit is trying to work with. 

Billions of years ago, the genetic code of primitive cells was passed from generation to generation and finally to multicellular organisms, then to invertebrates, and then to vertebrates around 600 million years ago. Because amphioxus, Pikaia, and their kin are transitional forms between invertebrates and vertebrates, the amphioxus can be thought of as the evolutionary gateway to humanity, to more developed brains, and to consciousness. Amphioxus, the gate, a creature born millions of year ago... Why do humans exist The answer quite simply is because amphioxus and its kin were born eons ego and lived to survive. 

Leary conjectures that the function of LSD and other psychedelics is to shift our awareness over the continuum of scale and structure represented by these eight levels or circuits. In other words, the brain can be thought of and utilized as a "lens for focusing on various scales of nature, represented by structures in our CNS—from the largest (physical/behavioral space) down to the smallest (sub-atomic space). The central idea is that all levels of energy/structure/scale are potentially accessible in consciousness. 

All mammals have the same kind of brain activation during sleep as humans. Whether or not they dream is another question, which can be answered only by posing another one Do animals have consciousness The answer to that question has been hotly debated. Many scientists today feel that animals probably do have a limited form of consciousness, quite different from ours in that it lacks language and the capacity for propositional or symbolic thought. 

Thought (item 6) and orientation (item 7) are both impaired by disablement of the aminergic systems and regional deactivation of the global and local memory systems of the brain. We want to know more about why declarative memories, which are presumably stored in the hippocampus and then moved out to the cortex, are so seldom available to dream consciousness. Clearly, all cognitive functions that depend on memory, except possibly emotional salience, are weakened in REM sleep. Dream consciousness is therefore both a poor analyser and a poor organizer of its content. Hyperassociativity and emotional salience are the rules that govern...
