Understanding Human Brain: Part 04

Do all species have the same types of neurons? 

No. Each set of neurons studied in each different type of species has proven that each animal species has a different, specific neuronal function system limited to its habitat. Which explains why (in the first chapter) we human cannot bring to talk animal dialect nor the animal can speak the human dialect.

To summarize the summary so far, we humans are born with a unique item called the Brain, which is constantly developing under immense genetic pressure. Also has a generalized capacity of knowledge, through natural selection of evolutionary history of self. Which is also centered on activity-based learning but with a particular skill set with constraints.

This simply means that our brain has multiple control systems but it has been found that there is no CEO in controlling any of these systems inside the brain. The problem now is that the brain seems to be working on its own but the power is not on a single hand. There are systems running simultaneously parallel inside the brain.


Who is the Boss then?

Being born, having to study the basics of life, and then get trapped in the race of life, we all assumed that this brain is just an automatic system that doesn’t seem to have control and we are in control of the brain.

Have you heard about the wallabies that live in the Kangaroo Islands of Australia? They have lived there for the last 9300 years approximately 9500 years. But for that last nine thousand five hundred years, they haven’t seen a single predator to their kind. The island became predator-free for these wallabies 9500 years ago.

This means the generation of wallabies that live today, or their parents, nor their parents, nor their grand great grand parents even, haven’t seen a predator for life. But, when presented with stuffed model versions of their predators, or the models of predators who are now extinct (9500 years ago), they get scared. And similarly not bothered when presented with non-predatory previously unseen animal modals.

Conclusion. General selection through evolution history. The Brain has millions of pre-wired neuronal connectivity that passes down through DNA and brain matrix which comes to this result of avoiding predators.

We humans think we are making all our decisions to act consciously and willfully. We all feel we are wonderfully united and connected and that some general inside the brain or above in the sky are controlling the central system.

“The brain has millions of local processors making important decisions. It is a highly specialized system with critical networks distributed throughout the 1,300 grams of tissue. There is no one boss in the brain. You are certainly not the boss of the brain. Have you ever succeeded in telling your brain to shut up already and go to sleep?”

― Michael S. Gazzaniga 

But also, his example of wallabies and various other researches done by the researchers, have finally come to a conclusion (proven), that it takes a minimum of 10,000 years of predator-free life for the specific template to disappear from the brain. Simply following, for us humans, it’s going to take 10,000 years of snake-free life for us to completely forget to be scared of a snake.

And it all depends on your own evolutionary history. And 10, 000 years is a lot of lives.
