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.

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.

There is some evidence that dreaming is necessary. When people or other mammals are deprived of REM sleep (by awakening them as soon as the characteristic REM and EEG dream patterns emerge), the number of initiations of the dream state per night goes up, and, in severe cases, daytime hallucinations-that is, waking dreams-occur.

The uncomfortable, as well as the miraculous, fact about the human mind is how it varies from individual to individual. The process of treatment can therefore be long and complicated. Finding the right balance of drugs, whether lithium salts, anti-psychotics, SSRIs or other kinds of treatment can be a very hit or miss heuristic process requiring great patience and classy, caring doctoring. Some patients would rather reject the chemical path and look for ways of using diet, exercise and talk-therapy. For some the condition is so bad that ECT is indicated. One of my best friends regularly goes to a clinic for doses of electroconvulsive therapy, a treatment looked on by many as a kind of horrific torture that isn’t even understood by those who administer it. This friend of mine is just about one of the most intelligent people I have ever met and she says, “I know. It ought to be wrong. But it works. It makes me feel better. I sometimes forget my own name, but it makes me happier. It’s the only thing that works.” For her. Lord knows, I’m not a doctor, and I don’t understand the brain or the mind anything like enough to presume to judge or know better than any other semi-informed individual, but if it works for her…. well then, it works for her. Which is not to say that it will work for you, for me or for others.

So far as I know, childbirth is generally painful in only one of the millions of species on Earth: human beings. This must be a consequence of the recent and continuing increase in cranial volume... Childbirth is painful because the evolution of the human skull has been spectacularly fast and recent.

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

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.

Curiosity and the urge to solve problems are the
emotional hallmarks of our species

Thus, an inhibition center developed below what in humans is the temporal lobe, to turn off much of the functioning of the reptilian brain; and an activation center evolved in the pons to turn on the R-complex, but harmlessly, during sleep.

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).

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?

He knew what he was experiencing was a basic error in programming, and he wished he could open up his brain and delete the bad code. Unfortunately, the human brain is every bit as closed a system as a Mac.
