Ok so, it turns out that when astronauts are in place for very long periods of time (about two-months) their brains go by way of apparent structural variations. That's fairly exciting and evidence of the amazing plasticity and means of the human mind. Now then, we now know what kinds of variations occur from research and it is exciting that the visuals of dolphin brains have also been imaged.
What do we know about the similarities of a human mind in place in a very low-gravity ecosystem as it learns to run in a 3 dimensional realm of motion and the mind of a dolphin which has structurally progressed to run in a equivalent very low-gravity ecosystem with motion in three-Dimensions (cite: one).
Why do I dare to look at or talk to this issue?
Properly, there was an exciting posting on the New Atlas internet site posted on January 31, 2017 titled “Astronauts' brains modify shape as they understand to shift in place,” by Michael Irving, which pointed out:
“The research found place travel variations quantity of grey matter in diverse elements of the mind, perhaps the consequence of shifting fluids because of to a absence of gravity, and the mind functioning extra time to relearn the essentials of motion in a unusual new ecosystem. People progressed to prosper in problems here on Earth, so it's not astonishing that when taken over and above our property turf, we're subjected to a selection of well being challenges. Devoid of gravity regularly pushing down on the entire body, bones and muscle tissue loses mass about time, an situation that astronauts on the ISS mitigate by way of training. ”
In this research the scanned (fMRI) of about two-dozen astronauts and all of them experienced their mind's grey matter modify + or – in diverse elements, the lengthier in place the more the modify. Now then, in accordance to Google Look for of human mind “General, grey matter occupies forty percent of the cerebrum,” and it turns out when you glimpse at a Dolphin mind although structurally diverse it contains a great deal of grey matter (Cite: two, three, four). And, and actually it is said that it's our 'gray matter' that will make us human, separates us from Dolphins (cite: five).
The human mind has a lot more by share, even nevertheless it is smaller in dimensions than a dolphin mind – probably dolphin brains do not require as a lot? Possibly a dolphin mind is a excellent design and style for very long-term place flight? Possibly some DNA research could guide us to clues? Possibly we can use this facts to aid us biologically engineer a greater mind to make it safer for individuals in very long-term place environments, without shedding cognitive skills and without well being risks.
Ok so, my hunch is that if we research the dolphin mind we can gain insights into why the human mind variations the amounts of grey matter in diverse elements of the mind when in a very low-gravity ecosystem and as astronauts understand to motivate in a entirely offered three-D ecosystem. Of training course, correct now we do not know a lot, but we know enough to get started taking into consideration this kind of factors and start new research to acquire edge of what we understand. Since we do not know particularly why this transpires but only have theories, we require to get to the base of it all. Maybe, people who've studied Dolphin brains could open a dialogue with NASA scientists who've studied the brains of returning astronauts. Believe on this.
