Why is the brain convoluted in appearance?

It's wrinkled convoluted appearance is due to a growth spurt during the fourth and fifth months of embryonic development, when the gray matter of the cortex is expanding greatly as it's cells grow in size. The supporting white matter, meanwhile, grows less rapidly; As a result the brain takes on the dense folds and fissures characteristic of an object with great surface area crowded into a small space.

Why doesn't the brain rest?

It depends on what you mean by "rest." The brain always has different levels of activity; some mental processes may use many areas of the brain while at other times the brain may be not as active. However, the brain is never completely inactive - if it is, then the organism is no longer living. Every bodily function is a result of the brain's work, and even when sleeping, the brain might be very active.

What is in-homogeneously enhancing mass of the brain?

These are imaging terms that radiologists use to describe a picture.

Inhomogeneous means that the whole mass does not look the same; the best I can describe is that it looks speckled. For example, a cyst that is filled with fluid will be homogeneous. Every part of what's inside the cyst will look identical, because it's just fluid in there. If the mass is made of different parts, of different densities, then it will appear inhomogenous, or heterogenous, on imaging.

Enhancing means that the mass brightens up with contrast, meaning that there is a lot of blood vessels feeding the mass. (this can sometimes be seen with cancer)

How long does it take the human body to start producing normal serotonin levels?

The time it takes for the human body to start producing normal serotonin levels can vary widely depending on factors such as individual health, diet, lifestyle, and whether any treatments or medications are involved. Generally, if a person begins making dietary or lifestyle changes, such as improving their nutrition or increasing physical activity, they might start to notice improvements in serotonin levels within a few weeks. However, for those undergoing treatment for serotonin-related issues, such as depression, it may take several weeks to months for medication to effectively balance serotonin levels.

Can Brain-Damage ever be fixed?

Brain damage is serious injury, It takes alot to fix it, it could cause memory loss, memory loss is caused in the brain area to run into something, hitting the brain area where memory is kept inside can be lost easily, by jerking it can cause damage, too much can cause you not to remember what happened, because of so much pain in the area. Doctors who are professional can fix it, they sure can! They can't fix memory loss, unless teaching the patient everything they don't remember. The two most important parts of the body are the brain and the neck. Well, we need lungs too. Patients might have to remember things on they're own. Serious brain damage can cause death if not fixed on time. Bruising your head or getting a tiny scratch on it doesn't matter, it will heal. But cutting it open or bruising the brain is an emergency, doctors can't fix that, only surgens. Profesional surgens. Over 1,000 people have died from getting damaged brains, broken skulls and anything having to do with the brain.It's very important to keep the brain safe. Nobody can live without a brain, Babies born with no brains is serious jobs for the doctors, getting brain-washed drains mist things out of the head, a special shampoo is the main part of brain washing, removing ANYTHING the shampoo touches around the brain, making it hard to remember it. So the answer to this question is: Yes! Sometimes no, surgens might have to.

What should be taken if there is a lack of serotonin?

Many doctors will purscribe SSRIs and SNRIs to treat serotonin deficiency but it is not a cure, just a bandaid and a poor one at that.

People with criticaly low serotonin levels are unable to benefit from the effects of SSRIs and SNRIs simply due to the brain's own inability to trigger the release of serotonin in any meaningful ammounts without outside stimulis (in my case due to heavy drug abuse in my youth).
