The 40 yr NHF study proves serum albumin in the CSF is the factor that cleans the brain however the level in the serum must be >47g.l and >240 mg in the CSF to remove the wastes such as amyloid. Inflammation controls albumin more than diet.
Why is corpus callosum important in the development of the brain?
It is where the two side of the brain the left and right do not communicate with each other so for an example if you are telling your self to move your right arm it may take a while for the left side to assist in what you want it to do
What part of the brain affects handwriting?
Handwriting is primarily controlled by motor regions in the brain, particularly the primary motor cortex and supplementary motor area. These regions coordinate the precise muscle movements needed for writing. Damage to these areas can result in changes to an individual's handwriting.
What does the perfect woman look like physically Her hair eyes nose height skin breast size?
There is no such thing as a "perfect woman" however when selecting a dating partner you shouldn't only focus on her physical traits.
Age
Personality
Common Intrests abd backround similarities
Values and Goals
And
Physical Traits
All of the answers you are going to receive are going to be based on personal preference to that person therefore making our comments useless
What percentage of people are left handed?
It varies, it is between 7-10% of the population
Also, it depends on what you call "left-handed". Does that mean you write with it? What if you write with the left and do everything else, like play the guitar and throw baseballs with the right? There's a few people out there that only use their left hand for writing and it feels more natural to use the right for nearly everything else. (The opposite of that is also true.)
For a number, though, when taking into account old people and young, the number is usually right around 7%. When looking at schools now, it is usually working out to right around 10%. I've actually noticed this... Usually high school (just a few years ago) there were about three left-handers in the class, me and two others, when class size was about 30 people.
I know there's a lot here, and it was a simple question, but I figured I'd try to open your mind a little.
Does touching the roof of your mouth stop a brain freeze?
Yes, touching the roof of your mouth with your tongue can help alleviate a brain freeze. The warmth from your tongue can help to slowly warm up the roof of your mouth and alleviate the cold sensation causing the brain freeze.
How does your brain selectively remember experiences?
The brain selectively remembers experiences by encoding and storing information that is deemed important or relevant, usually based on emotional significance or personal relevance. This process involves strengthening connections between neurons in a network and can also be influenced by factors like attention, repetition, and association with other memories. Additionally, the brain might prioritize short-term memory over long-term storage, focusing on retaining information that is currently useful or necessary.
What technology would be required to make a synaptic map of a living human's brain?
To create a synaptic map of a living human's brain, advanced imaging technologies such as electron microscopy combined with artificial intelligence algorithms would be necessary. These technologies would enable the high-resolution imaging and mapping of synaptic connections in real-time in a non-invasive manner. Additionally, the use of techniques like optogenetics to manipulate and understand the function of these synaptic connections could provide valuable insights into brain function and connectivity.
Does your brain continue to create neuron through out your life?
It's a bit ambiguous, if you mean by creating more cell then no, brain cell cease to duplicate once we reach a certain age around 2-3 years old (I'm not very sure about the time) since it's a highly specialized cell.
Is it possible to get brain damage from years of major depression and intense emotional trauma?
Yes, prolonged major depression and intense emotional trauma can lead to changes in brain structure and function, which may result in cognitive impairments or increase the risk for developing certain neurological conditions. Seeking help from mental health professionals and appropriate treatment can help mitigate these risks.
How can someone be alive if they're brain dead?
The answer to this very complicated question is both yes and no. My father was only 56 years old and had won the battle over stage 4 colon cancer when he went to the doctors office for a simple procedure he had had done several times before. This time was different - he went into cardiac arrest and his heart wasn't able to be started for over 20 min. He was pronounced brain dead. His body otherwise was healthy including his heart. He was brain dead because his heart had quit beating for 20 minutes and therefore his brain went without oxygen for 20 minutes thus causing him to become brain dead. He was on a ventilator for 48 hours and the doctor said even if he were to wake up right then he would not know anything or anyone. So basically be a vegetable. I know my father would not want to live this way. The doctors gave us a choice and we chose to take him off the ventilator and he passed away peacefully in about 5 minutes. Until then, his body was alive but his brain was dead.
The lower pons is a region located in the brainstem, which is responsible for relaying sensory and motor information between the cerebrum and the medulla oblongata. It also plays a vital role in controlling certain functions such as facial expressions, sleep, and consciousness.
old age affects memory because as you grow older you become more weak and feeble, the circulatory system starts to work slower and cant pump enough blood to the brain for it to work better. young age (Like babys) affects memory because they havent had enough neurons to enter their brain yet, also, they don't challenge their brain and are barely learning to do things
What is acute congestion of brain and stomach?
scarlet fever, poor man's disease or doctor phone option's(phone pictures sent for second option)
Researchers would be most likely to make use of fMRI (functional magnetic resonance imaging) to study brain activity while people recall familiar nursery rhymes. Specific brain areas that might be most active during this task include the language processing centers in the left hemisphere of the brain, such as the Broca's area and Wernicke's area.
What is the medical term meaning inherited autoimmune disorder characterized by gluten intolerance?
The medical term is "celiac disease." It is an inherited autoimmune disorder where the immune system reacts to gluten, a protein found in wheat, barley, and rye, causing damage to the lining of the small intestine. This can lead to digestive issues and malabsorption of nutrients.
What is the medical term meaning inflammation of the cerebellum?
The medical term for inflammation of the cerebellum is cerebellitis. It can be caused by various factors such as viral infections, autoimmune diseases, or bacterial infections. Symptoms may include dizziness, loss of coordination, and headaches.
What does the brain teaser deci sion mean?
The phrase "brain teaser decision" is unclear without context. It could refer to a decision-making challenge designed to be mentally stimulating, often in the form of a puzzle or problem. More details would be needed for a precise interpretation.
What connects the third and fourth ventricle f the brain?
The cerebral aqueduct connects the third and fourth ventricles in the brain.
Which animals brain is smaller than its nose?
Not entirelly sure though i do know that an osterichs eye is bigger than its's brain i feel sorry for it :(
When does a baby have normal brain waves?
Generally speaking, the first measurable brain waves can be captured on an electroencephalogram (EEG) around the 12th week of pregnancy.
Prior to that, the central nervous system of an embryo begins to develop in a sequence from "tail" to head. The brain tissue and the creation of a spinal cord are some of the early structures that begin the development process of the nervous system, but it will be longer before they are fully functioning.
In the fifth week after conception the first synapses begin forming in an embryo's spinal cord. Conception is traditionally defined as when the egg and sperm unite to form a new human being, initially called a zygote, however several years ago the American Association of Obstetrics and Gynecology decided to change the definition to a week later when the embryo implants in the uterus. To add to the confusion, obstetricians typically date pregnancy from about 3 weeks earlier at the time of the last menstrual period. Thus, it is very important to know what definitions are being used when studying prenatal (before birth) human development. Synapses are what connections of nerves are called. By the seventh week after the embryo begins development, these early neural connections permit the first movements of an embryo. The woman will not feel these movements but researchers can detect the movement through ultrasound imaging. These first movements do not involve fine motor movement but are trunk movements caused by the muscle and central nervous system development.
Other movements will follow--of the limbs (around eight weeks) and fingers (ten weeks), as well as some reflex movements such as hiccuping, stretching, yawning, sucking, swallowing, grasping, and thumb-sucking. By the end of the first trimester (first 3 months), a fetus's movement repertoire is remarkably rich, even though most pregnant women still feel none of it. Many women sense or feel the first fetal movements in the 5th and 6th months of the pregnancy; some may feel something as early as eighteen weeks of pregnancy.
Terminology:
A zygote is the first step in development of an embryo. The zygote formed from the union of 2 haploid cells (sperm and egg) to form one diploid cell. It is the first stage of the embryo. As the embryo is transported don the Fallopian tube to the uterus, further development occurs. At about one week, the blastocyst (name for that stage of embryonic development) implants in the uterine wall. 8 weeks after fertilization, when all organ systems have formed, the embryo is called a fetus up until birth, and then for the first 28 days after birth the medical term is neonate. These are the proper medical terms, but in English the term "baby" or "child" is used from the day the zygote is formed until a year - or several years - after birth. "Infant" can also be used for the first year after birth.
How big is an average chicken?
== == There are approximately 175 varieties of chickens grouped into 12 classes and approximately 60 breeds. That makes defining the "average chicken" very difficult.
The majority of chickens in North America are raised for either meat or eggs, in market terms, a broiler or fryer is a young meat chicken that can be cooked tender by broiling or frying and usually weighs in between 2 1/2 and 3 1/2 pounds.
A roaster is a young meat-type chicken that can be cooked tender by roasting and usually weighing 4 pounds or more.
A stewing chicken, hen, or fowl is a mature female chicken, often the by-product of egg production, are about 5 pounds plus.
This question does have an answer, though I won't give unless you come back stumped. You walk into a bank. You give the teller a check for $63.00. She will give you back 8 bills, what are they? Note. There are NO one Dollar bills in the change she will give you, and no change as dimes nickels quarters. The 8 bills she will give you will be higher than a $1.00 bill.
I know the answer to this you can use a $5.00 bill, a $2.00 dollar bill, and 100 pennies becasue you only said tht you couldn't use dimes, nickels, or quarters. And plz write bck to tell me if im write, or not, or close. THNX
