The brain's 65% is composed of lipids, half of which are phospholipids. The remaining 35% consists of proteins and other substances.<\/p>\n
Since phospholipids make up the cell membranes of the brain, protect nerve cells from external stimuli and damage, and are involved in the transmission of information between nerve cells (synaptic transmission), they play a very important role in brain function.<\/p>\n
Protein is the main component of the brain\u2019s nerve cells and nerve fibers, and is essential for brain development and function. Essential amino acids, in particular, are important for the production of neurotransmitters and support brain activity.<\/p>\n
The brain can't sweat out theories.
\nTo begin with, it is said that the brain's temperature is 1\u00b0C higher than body temperature.
\nWhen body temperature rises to 39\u00b0C due to heatstroke, the brain reaches 40\u00b0C, and cells in the cerebrum begin to suffer damage.
\nIf that happens, you won't be able to make sound judgments\u2014you might not realize that you need to drink water, or you might lose the ability to regulate your body temperature.<\/p>\n
The nose and ears are the only organs that cool the brain from the outside.
\nThat means the face masks that are all the rage right now might actually be contributing to heatstroke.
\nAnother way to cool the brain is to cool the large blood vessels, which in turn cools the brain through the blood.<\/p>\n
Proteins are sensitive to heat, and they begin to denature at temperatures above 40.5\u00b0C.
\nAs Hiroyuki, the founder of 2channel, once said, \u201cIt\u2019s like a hard-boiled egg\u2014once it\u2019s set, there\u2019s no going back.\u201d
\nThat's roughly how it feels.<\/p>\n
The fact that once a change occurs, it cannot be reversed means that even if the person survives, they may be left with a disability.
\nData has also shown that among cases of Grade III heatstroke, only about 20% of patients survive without suffering any lasting disabilities and are able to return to their normal lives.<\/p>\n
The body is basically designed to prevent substances that are harmful to the brain from entering it.
\nVarious substances necessary for life\u2014such as glucose and amino acids\u2014are taken up by the brain from the bloodstream, but there is a mechanism called the blood-brain barrier that prevents substances that should not enter the brain from doing so.<\/p>\n
However, organic solvents and alcohols manage to get through the barrier.
\nAnd yet, even with drugs designed for the brain, getting them past this barrier remains a challenge.<\/p>\n
I'm sure you're all aware that one of the main characteristics of organic solvents and alcohols is their degreasing effect.<\/p>\n
The saying, \u201cIf you play around with paint thinner, your brain will melt,\u201d isn\u2019t just a scare tactic\u2014it actually does melt.<\/p>\n
