Neurons are living cells with a metabolism. And they need glucose in order to function. Glucose is the fuel of the brain, just like gasoline is the fuel of your car.
Why do we have a brain in the first place? Not to write books, articles, or plays; not to do science or play music. Brains develop because they are an expedient way of managing life in a body.
There is something fundamentally fascinating about the mechanics, I guess, of the human body and where consciousness and mind exist, and what you can do with the mechanics of the body while keeping those intact, and where those two cross over.
There's that effect that is very physical, very down there at the synaptic level, which really means microscopic cellular level, but also molecular level, because all of those structures are operating on an electrochemical basis and so the changes there are very important.
While the hippocampus itself doesn't store memories, it serves to triage our experiences based upon their survival significance.
Along with our many human propensities, we evolved a huge cerebral cortex with which we make decisions.
When looking at the brain, it is important to go beyond its structure to its function. This is because often in cognitive disorders, the structure of the brain is intact, but its function is compromised.
The ability to sympathize with those around us seems crucial to our survival, and it's connected to the mirroring functions of the brain.
In our skulls, we carry around 3 pounds of slimy, wet, greyish tissue, corrugated like crumpled toilet paper. You wouldn't think, to look at the unappetizing lump, that it was some of the most powerful stuff in the known universe.
The amygdala is like a point guard in the emotional part of your middle brain. When it is overwhelmed, it hijacks you away from being able to access your upper rational brain and think and assess what to do. It essentially disables your ability to think.
Your experience is a dream; so is my experience. This stuff about how the frontal cortex is repressed during dreaming, lucid dreaming presents an obvious contradiction to it. The only difference is sensory input.
