In a way, science might be described as paranoid thinking applied to Nature: we are looking for natural conspiracies, for connections among apparently disparate data. Our objective is to abstract patterns from Nature (right-hemisphere thinking), but many proposed patterns do not in fact correspond to the data. Thus all proposed patterns must be subjected to the sieve of critical analysis (left-hemisphere thinking).

[D]umb evolutionary processes have dramatically amplified the intelligence in the human lineage even compared with our close relatives the great apes and our own humanoid ancestors; and there is no reason to suppose Homo sapiens to have reached the apex of cognitive effectiveness attainable in a biological system.

More than ninety-five percent of your brain activity, as you consciously read this sentence, is being used by your subconscious mind.

It is well understood in psychology that the subconscious mind has the dominant influence on human decision making, and therefore the pivotal role of the subconscious, for you to achieve success, is inescapable.

Major scientific insights are characteristically intuitive, and equally characteristically described in scientific papers by linear analytical arguments. There is no anomaly in this: it is, rather, just as it should be. The creative act has major right-hemisphere components. But arguments on the validity of the result are largely left-hemisphere functions.

Someone should do a study of the human brain and how quickly it can adjust to luxury.

Our minds have the incredible capacity to both alter the strength of connections among neurons, essentially rewiring them, and create entirely new pathways. (It makes a computer, which cannot create new hardware when its system crashes, seem fixed and helpless).

Perhaps the locale of the subjunctive mood will one day be found. Will Latins turn out to be extravagantly endowed and English-speaking peoples significantly short-changed in this minor piece of brain anatomy?

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.

The brain makes up l/50th of our body mass but consumes a staggering 1/5th of the calories we burn for energy. If your brain were a car, in terms of gas mileage, it’d be a Hummer. Most of our conscious activity is happening in our prefrontal cortex, the part of our brain responsible for focus, handling short-term memory, solving problems, and moderating impulse control. It’s at the heart of what makes us human and the center for our executive control and willpower. The “last in, first out” theory is very much at work inside our head. The most recent parts of our brain to develop are the first to suffer if there is a shortage of resources. Older, more developed areas of the brain, such as those that regulate breathing and our nervous responses, get first helpings from our blood stream and are virtually unaffected if we decide to skip a meal. The prefrontal cortex, on the other hand, feels the impact. Unfortunately, being relatively young in terms of human development, it’s the runt of the litter come feeding time.

C++ is an insult to the human brain

This looks very much as if the integration of the day's experience into our memory, the forging of new neural links, is either an easier or a more urgent task. As the night wears on and this function is completed, the more affecting dreams, the more bizarre material, the fears and lusts and other powerful emotions of the dream material emerge.

There is another connection between infancy and dreams: both are followed by amnesia. When we emerge from either state, we have great difficulty remembering what we have experienced. In both cases, I would suggest, the left hemisphere of the neocortex, which is responsible for analytic recollection, has been functioning ineffectively.
