How do you know the things you know?
Information is stored in your brain in the form of electrical signals. When you learn something, a specific pathway of signals is set up, which can be activated whenever you need that information again. Scientists are still not exactly sure how this works, but it does!
What is different between mind and brain?
Many theories have been put forward to explain the relationship between what we call your mind (defined as the conscious thinking 'you' which experiences your thoughts) and your brain. In fact, it's fair to say that this is one of the fields of philosophy which is most up in the air (although, of course, all of philosophy is up in the air to some greater or lesser extent).
However, it is also a field for which the advancing discipline of neuroscience holds out some hope of a solution. In the last half of the 20th century we have learnt how to actually 'see' thoughts play out in the brain on magnetic imaging devices which show activity in different areas of the brain. We have learnt which parts of the brain perform which functions, although it would be wrong to depict this as a vindication of the idea behind phrenology: it is not as if discreet chunks of the brain perform discreet functions.
Are antidepressants dangerous to brain memory?
Some studies have shown that some antidepressants can affect short term memory for some people, yes. Be sure to consult your doctor to see if this is something that might be happening to you, and don't stop taking an antidepressant without talking to your doctor. Some of them have negative effects if you just stop taking them cold.
What does the cerebral cortex deal with?
[easy answer]
It's most of your brain and deals with consciousness and self-awareness and pretty much all the stuff that makes us think like humans and not like dogs and cats.
[scientific answer] The cerebral cortex makes up about 75% of the human brain. It is made up of several layers of cells and is about 1/8th of an inch thick. This thin collection of cell layers, however, is very tightly folded, somewhat like a crumpled sheet of paper, so that a large amount of it takes up only a small amount of space. Activity in the cerebral cortex is essential for many of the qualities, skills, and abilities that make humans different from all other animals. In fact, if you lost your cerebral cortex, you would lose your self-awareness, your ability to respond with foresight and deliberation to the environment, your ability to relate your past and future to the present, your ability to speak and understand language, and many other higher functions.
Does Brain from the TV show Pinky And Brain ever really take over the world?
Brain creates "Chia Earth", a full sized replica of earth made out of paper mache and convinces the entire population of Earth to relocate to his "Chia Earth" with the promise of FREE T-SHIRTS! His plan succeeds and Brain crowns himself the new ruler of the world (although he and Pinky make up the entire population). However, Brain's rule is soon ended when a meteor collides with the real earth and he and Pinky are forced to flee to the newly populated "Chia Earth".
A barangay is the smallest administrative division in the Philippines - a village, district, or ward.
Where does the effect of TMS stimulation cease in the brain?
The effect of TMS depends on the coil design and other factors (Hair, thickness of the bone, location of the coil etc.) as the Link provided shows, the magnetic field distribution of the figure 8 coil penetrated the cortex approximately 1.5 centimeters. If you however ask WHEN the effect subsides it depends again but lets say 15 minutes of 1Hz stimulation to the fronto temporal lobe will have no significant effect on the Stroop task any more after approximately 15 minutes after stimulation has ceased... that is at least what I found in my experiments. Other protocols however can elicit changes in the brain with a longer duration.
Does psychosis cause brain damage?
Some doctors say that it can eat away at the white matter of the brain and also enlarge ventricles implying brain damage. Most top psychiatrists I've talked to say "the jury is still out" on the matter.
So as of now, no one really knows. But even if it did cause brain damage, as long as you take your meds, you may never have a psychotic break again. Just work hard at brain exercises and reading and writing, (that's what I do,) and new neurons will regenerate and help you get back to or close to normal. However the disease of schizophrenia itself can cause neuropsychological damage throught depletion or too much neurotransmitters. So if you have schizophrenia, most studies say you will stay about the same for life.
However, some of the best doctors in the country at The Freedom Trail Clinic told me that many people do improve significantly, despite these studies. So I guess it would depend on the person.
When does moral reasoning develop in the brain?
We all develop at different rates and reach the moral reasoning point at different ages.
The Catholic Church used to say it happened at about 7 or 8 - the ages at which most children made their first Confession of sins. I don't know their current thinking.
Certainly we are born with a strong sense of right and wrong - many young children notice injustices which involve their world - one child getting more of something than another, or random punishments meted out for offences they weren't aware of. But much of this is self-oriented and it usually takes a few more years for the leap to be made away from their own involvement in a situation to an appreciation of morality as a concept.

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
