“The rules of quantum mechanics allow attention to influence brain function.The release of neurotransmitters requires calcium ions to pass through ion channels in a neuron. Because these channels are extremely narrow, quantum rules and the Uncertainty Principle apply. Since calcium ions trigger vesicles to release neurotransmitters, the release of neurotransmitter is only probabilistic, not certain. In quantum language, the wave function that represents “release neurotransmitter” in a superposition with the wave function that represents release neurotransmitter” each has a probability between 0% and 100% of becoming real. Neurotransmitter release is required to keep a thought going; as a result, whether the “wash hands” or “garden” thought prevails is also a matter of probability. Attention can change the odds on which wave function, and hence which thought, wins.”

“The brain is provided with a number of enzyme systems which serve to co-ordinate its workings. Some of these enzymes regulate the supply of glucose to the brain cells. Mescalin inhibits the production of these enzymes and thus lowers the amount of glucose available to an organ that is in constant need of sugar. When mescalin reduces the brain’s normal ration of sugar what happens? Too few cases have been observed, and therefore a comprehensive answer cannot yet be given. But what happens to the majority of the few who have taken mescalin under supervision can be summarized as follows…”

“When the brain runs out of sugar, the undernourished ego grows weak, can’t be bothered to undertake the necessary chores, and loses all interest in those spatial and temporal relationships which mean so much to an organism bent on getting on in the world. As Mind at Large seeps past the no longer watertight valve, all kinds of biologically useless things start to happen. In some cases there may be extra-sensory perceptions. Other persons discover a world of visionary beauty. To others again is revealed the glory, the infinite value and meaningfulness of naked existence, of the given, unconceptualized event. In the final stage of egolessness there is an “obscure knowledge” that All is in all—that All is actually each. This is as near, I take it, as a finite mind can ever come to “perceiving everything that is happening everywhere in the universe.”

“The purpose of all of this (left hemisphere's way of choosing denial or repression over considering an anomaly) is to impose stability on behavior and to prevent vacillation because indecisiveness doesn't serve any purpose. Any decision, so long as it is probably correct, is better than no decision at all. A perpetually fickle general will never win a war.”
