Why is corpus callosum important in the development of the brain?

User Avatar

Asked by Wiki User

The corpus callosum is a structure that connects the two hemispheres of the brain, allowing for communication and coordination between them. It plays a crucial role in integrating information processing, motor skills, and cognitive functions. Damage to the corpus callosum can result in impaired communication between the two hemispheres leading to various cognitive and motor deficits.

What part of the brain affects handwriting?

Asked by Wiki User

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?

User Avatar

Asked by Sarahwoods1101

Physical appearance varies greatly from person to person, and there is no universal definition of the "perfect woman." Beauty is subjective and diverse, encompassing a wide range of characteristics. It's important to remember that everyone is unique and beautiful in their own way, regardless of specific physical features.

What percentage of people are left handed?

User Avatar

Asked by Wiki User

It varies, it is between 7-10% of the population

AnswerThere are a lot of different answers to this, believe it or not, because the people doing the studies generally look at one age group (or very few different groups). Way back when, all kids in school were encouraged to use their right hand for writing - even to the point that they got punished sometimes. It's much more common for kids and young adults to be left-handed now because of this reason.

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?

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Fatfast

Yes, the brain continues to create new neurons through a process called neurogenesis, particularly in regions like the hippocampus which is involved in memory and learning. This process can be influenced by factors such as physical exercise, diet, and mental stimulation.

How does age affect memory?

User Avatar

Asked by Wiki User

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

Which specific brain areas are most active while people recall familiar nursery rhymes researchers would be most likely to make use of a(n)?

User Avatar

Asked by Wiki User

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 does the brain teaser 'knee ur full of' mean?

User Avatar

Asked by Wiki User

KNEE

UR FULL OF

You're full of baloney/bologna. This is derived from the fact that "ur" is a chat abbreviation for "your" and the phrase "ur full of" is below "knee". When you pronounce it, it sounds like "you're full of baloney". Baloney is a colloquial name for bologna - you're full of baloney/bologna is a slang term.

When does a baby have normal brain waves?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

== == 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.
