Why Can’t We Get the Brain Right?

brain Why Can’t We Get the Brain Right?

For many decades It was assumed that the human brain must be special, as superior to the brains of other mammals as our minds are. This specialness was never seriously questioned, and even basic facts, like asserting that the human brain contains 100 billion neurons, were arrived at with surprising casualness.

In an interesting 2013 TED talk, the articulate Brazilian neuroscientist Suzana Herculano-Houzel offers clarity for the first time on several of the basic issues. After devising a way to dissolve brain cell membranes so that only the nuclei remained, and isolating them to be counted, she determined that the human brain contains 86 billion neurons, the most of any primate. Even though the human brain is a small fraction of our total weight, it uses 25% of a person’s daily calorie consumption.


That may seem like an incidental fact, but Herculano-Houzel makes it the cornerstone of her argument, which declares that the human brain isn’t special. We have primate brains, she says, that are in proportion to our primate relatives like chimpanzees and gorillas. But in an odd evolutionary twist, chimps and gorillas cannot sustain the calorie load of an immense brain by eating raw food. Typically, a great ape feeds for eight hours a day to sustain its large body, and over time a choice was made to prefer a very large body with a smaller number of neurons.

Do Your Genes Run You or Vice Versa?

overwieghtmom Do Your Genes Run You or Vice Versa?
There's a disturbing trend in science to try and prove that human beings are machines, and where this was once a metaphor, it is being taken more and more literally. We are told that a brain hormone is responsible for falling in love or a mother's affection for her newborn baby. Brain areas that light up on an fMRI scan supposedly indicate that a person is depressed or prone to criminal behavior and much else. Besides being brain puppets, we are supposed to believe that our genes program us in powerful ways, to the point that "bad" genes doom a person to a host of problems from schizophrenia to Alzheimer's.


There needs to be a clear rebuff of this notion that human beings are mechanisms, and the fact that science has a wealth of findings about both genes and the brain doesn't make the notion any more valid. The general public isn't aware, for example, that only 5% of disease-related genetic mutations are fully penetrant, which means that having the mutation will definitely cause a given problem. The other 95% of genes raise risk factors and in complex ways interact with other genes.

The Smartest Diet for Your Brain

The Smartest Diet for Your Brain

In the scheme of things, your brain is one of your greatest treasures. Learn to take care of it! Feed it what it needs. This post from the archives will fill you in of brain nutrition basics. And, by the way, you won't miss a beat on flavor! Brain healthy foods include some delicious favorites. I recommend making them part of your repertoire, and weaving them into your day on a regular basis.

It starts with the “p” word — and that would be “plants.”

A flood of new and surprising research is emerging about the role that plants play in brain health. For example, a study on the MIND diet — a combination of the Mediterranean and DASH diets — published online in Alzheimer’s & Dementia, The Journal of the Alzheimer’s Association — concluded that people who eat more dark, leafy greens at least once a day have substantially slower cognitive decline with age than those who eat the Standard American Diet (SAD).Bingo!

Will the Gut-Brain Connection Revolutionize Wellness?

Will the Gut-Brain Connection Revolutionize Wellness?

Three decades ago, the brain lost its sovereignty as the seat of thinking, feeling, and the operation of intelligence. In fact, those processes began to escape the confines of the nervous system itself. All of this occurred when it was discovered that various “messenger molecules” associated with the brain are in fact circulating throughout the body via the bloodstream. Every cell is eavesdropping on the brain’s activity, sending and receiving messages identical to those that the brain processes.

 

Over the next three decades, the realization that what we dub “intelligence” is a holistic feature of the body, the main difference being that outside the brain, this intelligence is nonverbal. The immune system’s incredible ability to identify and combat invading bacteria and viruses, in fact, has earned it the nickname of the floating brain. Everywhere researchers looked, new avenues were opening in a virtual information superhighway that reaches everywhere, and now it is possible to redefine wellness in terms of a “whole system” approach that has no need to recognize the artificial boundaries between brain and body, neurons and other cells, or even the distinction between human DNA and the countless other microbial genes that reside inside us.
