What Is So Special About The Human Brain? by Suzana Herculano Houzel
Posted by freedomforall 7 years, 5 months ago to Science
The human brain is puzzling -- it is curiously large given the size of our bodies, uses a tremendous amount of energy for its weight and has a bizarrely dense cerebral cortex. But: why? Neuroscientist Suzana Herculano-Houzel puts on her detective's cap and leads us through this mystery. By making "brain soup," she arrives at a startling conclusion.

As to being president, look at what we got with in the past. Were they intellectually consistent and freedom preserving? Some were mass murderers and others control freaks. A fully functional android is a long way off, but maybe an android neighbor wouldn’t attack me while I was mowing my lawn...
And I hold that they all have their basis in the false premise that anyone can duplicate the programming of the human brain, and produce not only machine intelligence but machine reason. Such an entity would of necessity have the right of citizenship in the country of its creation, and have the right to change citizenship, even to hire transport if necessary. Now imagine such a creature building enough tele-operators to design its own next generation. That second-generation machine would then be a natural born citizen within the meaning of Emmerich de Vattel's Law of Nations. (That could even apply to the first generation, if you grant to the creators of that system the title of "parent.")
HAL for President? Colossus for President? SkyNet for President? (Well, that's a little different; SkyNet was a power-mad and mass-murdering military insurrectionist.) "Data" for President?
Are you sure...?
Man, (Humans) can not live by brain alone anymore in complex times like they did in simple pagan bicameral times where all that cooked/raw, food and neurons were dedicated to dealing with the stresses of survival.
Today, one's survival depends upon the mind otherwise those reliant on only their brain must "Take" what they need or perceive they need, to survive.
In all seriousness, one can affect the neural pathways in the brain by the choice of the decisions one makes. And this isn't necessarily purely chemical interactions such as psychotropic drugs or alcohol. Psychological studies have been done demonstrating that kids who watched "Sponge Bob Squarepants" had decreased IQ's. Others studies have shown that engaging one's brain in intellectual activities such as Sudoku on a daily basis strengthens and encourages synapse response - especially in the elderly.
To be completely fair to progressives and other leftists, I think they have the same number of neurons, they just don't exercise them. Thinking is actual hard work as you encourage the brain to create the neural pathways which then facilitate critical thinking. Mindsets are as much literal and physical in the brain as they are mental constructs. Habits form in the brain as well-used mental pathways, which is why it is so important to form positive ones. I believe that the vast majority of leftists have never gotten in the habit of real, critical thinking and that this is one of the reasons why they react so violently when confronted with it. It is in actuality a response to an alien condition to their brains which must be consciously overridden (in the form of humility) so as to allow their brains to begin building the alternate pathways necessary to cognitively deal with these thoughts.
Once conscious...meaning one has gained a mind, That mind is the main source of insight, views of self and behavioral control...at that point, the inner voice is that of the mind, or the voice of self.
My work involves the connections from the brain, to the mind and the quantum field.
The cooking and brain-cost connection is important but it doesn't explain the driving force in evolution. The driver must be an advantage to the larger brain, and that cannot be simply survival (hunting etc) otherwise it would be more common in other animals. My studies lead me to conclude that the driver is our storytelling ability. That is the uniquely human brain function which has been exaggerated over time due to mate selection. Storytelling has nothing to do with survival, and most traits which are not survival-based tend to become over-developed (eg. bright bird plumage)
I think there are a couple of leaps in there that aren't particularly well-founded however. The first is that just because you create brain soup to measure the sheer number of neurons doesn't measure overall cognitive ability. Many animals devote significant neural capacity to sensory organs (especially olfactory and auditory) which in comparison outclass human abilities (sharks and dogs come to mind). Thus I think that a far better comparison would be to build upon the work she has done but to individually divide the brains for comparison into functional areas prior to liquefaction and comparison.
I also echo the comments regarding simply cooking one's food, and would instead prefer a far more rigorous dietary examination. A cow has five stomachs to aid in the digestion of plant materials and is far more efficient at such tasks than humans, where that fiber simply passes through us. Primates are not vegetarian with specialized stomachs, so a diet heavy in plant fibers is going to be necessarily inefficient. Take koalas for example, who spend nearly their entire days eating eucalyptus leaves. A primate that subsists primarily upon proteins, however - especially animal proteins - can be much more efficient.
I applaud her for her initial work, but suggest that she draws several conclusions which we will find do not follow from the abundant evidence.
