When a brain works with its maximum efficiency?
When it's working on a problem that can be taken care of by one of its specialty sub sectors.
For men that's geometry .... for women it's facial recognition.
What is an introduction to brain drain?
"Brain drain" is the large-scale emigration of a large group of individuals with technical skills or knowledge to another geographical area, often another county.
What did Egyptians do with the dead person's brain?
Egyptains took the brain out of the persons dead body with a hook that they put into the nose and took it out peice by peice. they thought that it was not important for yor body and they left the heart in becuae they thought that IT was the most important part so they left it in and took the other organs out and just threw them away.
Can you take out someones brain completely without killing them?
I think you should be able to, as long as the lungs and heart are still working, but I'd rather you not take the risk. -Alexa
How do you practice for a spelling test?
What consistently got me the "A's" in spelling was the 'practice by rote' method. Visually looking at the words and spelling them aloud ten times each ingrained them in my memory even until today, 45 years later (plus or minus, I never was really all that great at math!)
How do brain connections affect learning?
Because the connections in the brain are what makes your brain work, without connections there's nothing to process or indicate, the process of learning is severely affected by these connections, and if it weren't for them, well, my name wouldn't be Mr. Science 8=D~>-|o
What part of the cerebellum is involved in planning rather than executing movement?
The lateral part of each hemisphere
What is mater NOT made out of?
Matter is not made out of energy, as energy and matter are distinct concepts in physics, even though they can be converted into one another according to Einstein's theory of relativity. Additionally, matter is not composed of abstract concepts like thoughts, emotions, or ideas, which exist in the realm of consciousness rather than physical reality. Furthermore, matter does not consist of non-physical entities such as vacuum or empty space, which lack tangible properties.
What is the answer to level 38 on busta brain?
to finish level 38 u have to put in "once upon a time" since the one is above a time
Yes, a chicken is a vertebrate. This means they have a backbone. All vertebrates, and some invertebrates, have a brain.
or the simple answer, yes, chickens do have brains.
Is there any technology to control the brain waves?
There is a technology called brainwave entrainment that uses audio to alter or influence brainwave activity. Basically, you listen to a special audio CD with a pair of stereo headphones. In one channel a particular frequency is introduced, and in the other a slightly different frequency is played. The difference between the two signals is called a beat frequency. The developers say that the brain interprets this beat frequency, and causes brainwave synchronization at the beat frequency between the two hemispheres of the brain. There are a number of commercial producers of these disks. Hemi-Sync, HoloSync and Dr. Jeffrey Thompson are some of the more well known producers. I've tried them and found them to be very relaxing. Whether this is due to a measurable effect on my brainwaves I don't know but there is something happening when I listen. I prefer the Jeffrey Thompson CDs because they are more musical. Visit their websites for more info. There are also software packages that allow you to create you own brainwave entrainment audio. Yes. It's called the electric chair, and it makes the brain waves stop very quickly. I loved the last answer best but yes there is. It's called an alphawave inducer. Basically, a set of flashing lights that fill your entire field of view (that parts important) and that blink between 3 and 7hz. The blinking lights cause the brainwaves to sync with them. I've built one once using plans from an electronics mag and bought one that I use now for about $50. There are also high end devices (called NovaPro or something like it) that do the same thing for hundreds of bucks. And yes they really do work. Great for relieving stress or getting rid of a tension headache. The first one I built was a set of swim googles with leds in the center of them and a rubber coating poured over them. The electronics was a quick 555 timer circuit run off a 9 volt battery. Nothing complicated.
Electrical impulses bypasses what area of the brain?
The electrical impulse bypasses the concious areas of your brain so you don't think about subconcious things, like reflex actions for example. This is to help you in dangerous situations and to help you survive.
Why is the brain called a brain?
The term brain comes from the old English braegen, possibly from Greek brekhmos (forehead).
It is the English derivitive of an old Germanic word for "grey mush in the head" as opposed to grey mush in the bones (what we now call marrow). Ancient peoples did not know the function of the brain, and in fact many languages lumped marrow and brains together with single word. As our knowledge about the function of the brain grew, we kept the language of our ancestors who simply viewed the brain as waste/refuse.
How many GB does the brain have?
Gigabytes are a measurement of digital information storage. Not for mental storage.
A typical adult brain contains 15 billion to 200 billion neurons. Assuming we use the lower figure, the brain is capable of remembering 2 the 10th billion power bits of information.
Basically, the brain can store up to about 10 billion encyclopedia pages worth of information.
What is the function of the medulla oblongata?
The medulla oblongata is the most vital part of the brain because it is the control center for breathing, blood pressure and heart beat among other involuntary body functions not under conscious control. Because these functions are necessary for human life, damage to the medulla oblongata can be fatal.
There is only one medulla oblongata in the brain. The medulla connects the brain and the spinal cord, and is the lower half of the brainstem.
Respiration - chemoreceptors
Cardiac center - sympathetic, parasympathetic system
Vasomotor center - baroreceptors
Reflex centers of vomiting, coughing, sneezing, and swallowing
How can hydrotherapy help a person suffering from traumatic injury?
Hydrotherapy may ease the stress of recovering from trauma.
The brain is STILL a mystery to the scientists and humans today is just because the brain is and always will be a mystery. The part that know one knows about isn that it functions very different then any thing in the world. That means that it will always be a mystery.
What is meant by right brain and left brain people?
The idea that we have a dominant brain hemisphere has been generally discredited, mostly because it is not even scientifically true. The the thought that left brainers are logical, good with mathematics and language, while right brainers are creative and artistic has no basis in fact but has captured the imagination go the same groups that believe in other pseudoscience babble.
Why does your brain have crevises?
They are called sulci (singular - sulcus). These are folds of the brain designed to give it more surface area.
For a reasonable layman's definition of sulci, the Wikipedia article for 'Sulcus (neuroanatomy)' gives an introduction.
(I'm a neuroscience student.)
The brain uses the surface area to store information. This area is finite in size and when a person is born, its smoothe. As you age you need more space to store information and the brain makes ridges and valleys on the surface, thereby adding more pages for the book where we store memory.
