Our brains consume about 20% of the energy our bodies use, and to invest that much energy in a function that is only 10% efficient makes no evolutionary sense.
While many of the threats are symbolic, evolutionarily, our brains have evolved to deal with physical threats to survival that we had to quickly respond to.
For instance, when we see another person experiencing some emotion such as joy, sorrow or anger, our brain attempts to fire the same synapses to relate to the observed emotion.
As an unexpected bonus, our brains turn out to be{362} powerful enough to accommodate a much richer world model than the mediocre utilitarian one that our ancestors needed in order to survive.
Our brains respond to these natural shapes as“background,” while the more simple, unscaled, cubist shapes of the built environment stand out and demand our attention.
Even though we believe it is quite clear with our own eyes: there is no square in the middle, our brain structures the image looking at familiar patterns.
When we concentrate intently on one thought, emotion, or activity, we have fewer stimuli to process and our brain can move into the intense focus of Alpha waves.
One of the primary discoveries from researchers like Gilbert is that extreme inescapable situations often trigger a response from our brain that increases positivity and happiness.
Our brains are more complicated than other animals' brains and, as more than half the human brain is made of fat, 9 it stands to reason that we need custom-made fatty ingredients to help build that complexity.10.
During saccades, even if we are not actively thinking about moving our eyes, our brain is still quickly working to land our focus precisely on spots that hold important information, such as the eyes of a person that you are talking to.
Our brains are set up for an agrarian, nature-oriented existence that came into focus five thousand years ago,” says Michael Gurian, a family therapist and author of The Good Son and The Wonder of Boys.
Neuroscientist Matt Lieberman describes in his book, Social: Why Our Brains are Wired to Connect, our brains are so attuned to our relationships with other people that they quite literally treat social successes and failures like physical pleasures and pains.
The entire body, as well as our brain waves in a relaxed state, vibrates at a fundamental frequency of about 8 cycles per second, literally entraining and attuning us to the basic electromagnetic field of the earth itself!
