Ten myths about the human brain

mind-brain-electrodes_8903_600x450

I want to remember everything as I get older!

Science continues to expand our understanding of how the brain works. This mysterious organ that drives the entire machine suffers from being greatly misunderstood. Here are ten common misconceptions about the brain that should set you straight.

1. Humans only use 10% of their brain. Perhaps one of the greatest misconceptions of our time, this myth is empirically false. Originating from the idea that perhaps only about 10% of the neurons of the brain are operating at any given moment, but this concept is decidedly different than not using the other 90%. The truth is closer to the idea that we only push ourselves to about 10% of our entire capacity.

2. Video games will damage the brain. In this day and age of video gaming, this myth is also fairly inaccurate. Even though the advent of video gaming is a recent phenomenon and there is not a great deal of study about it, researchers have found the playing video games actually teaches your brain to process information in great amounts and much faster, thus improving brain power.

My brain can only take so much!

3. The bigger the better. There has never been any substantial evidence that the size on one’s brain makes you smarter. Men’s brains are by a rule larger than women’s, thereby debunking this myth immediately. If the brain is not used, it won’t matter what the size.

4. A damaged brain cannot regenerate. Science now has empirical evidence that the brain can engage in neurogenesis, a form of cellular rebuilding, although it’s not guaranteed.

5. Aging leads to a loss of memory. While it is a common condition, it is not a given that age will weaken the ability to remember. An active brain can be exercised with regular thinking and a healthy diet.

6. The brain is riddled with holes. A completely false mythology, referring perhaps instead to the parts of the brain where neurons are not firing.

7. Depression begins in the brain. This is not only a myth but a dangerous one as well. People who believe that depression is just a series of “bad thoughts” can do real harm. Depression is a much more complicated condition caused by any number of reasons. No one decides to be depressed.

I never knew all this goes on inside my head.

8. Left Brain, Right Brain. The truth is, no one operates from solely the left or right brain. Some people may be stronger on one side or the other, but all humans use both sides of the brain.

9. The brain is a giant computer. Just the opposite, the brain is so much more complicated than any computer, that it’s an insult to one’s brain to make this comparison. It was probably started because the first computers were roughly based on what was known about the brain at the time.

10. We learn better through a subliminal approach. While listening to information while in a relaxed or even sleep state works well for some, it is just as likely that it won’t work for others. We all learn in our own best way.

How to Read Someone’s Mind

Reading someone's mind

Reading someone's mind

Reading someone’s mind through telepathy has a long and legendary history. But if you want to have this ability too, you may have to rethink what mind reading is. If you envision closing your eyes and having someone from across a stage project their thoughts into yours, so that you can “hear what they’re thinking,” you are out of luck. People claim to be able to do this but they don’t teach their methods to anyone. However, mind reading is still open to you, and everyone, really, through a technique called Cold Reading.

Cold Reading is actually a set of techniques developed to give the appearance of reading someone’s mind. In fact what you’re reading are signals your subjects, i.e. the people whose minds you intend to read, are subconsciously giving you without their knowledge.

Sounds pretty cool, huh? It is. It’s great at parties and in business. For the most entertaining form of Cold Reading, watch Derren Brown’s show on British Television: the Illusionist. This highly popular show exhibits Derren Brown, a mind reader who explains and dissects his ability, reading people’s minds, hypnotizing them, and even controlling their actions. In one episode he walks through the streets of a bustling city asking people for their wallets, phones, and watches, and without so much as a moment’s hesitation, they all give them to him.

Cold Reading won’t give you abilities like Derren Brown’s, at least not at first. Here’s how to Cold Read: First, choose a subject carefully. The main ways to do this are to either to pick someone you know already, but who doesn’t know you; to ask for a volunteer from the audience, because presumably the volunteer will want you to be able to commune with the dead or do whatever you claim to be able to do; or to “shotgun the audience,” which means you make broad, general statements to a group of people such as “I’m sensing someone here has problems in their marriage.”

The next step is to profile your subject. This means you learn as much about your subject from their body language, dress, and reactions to you. Everything visible about a person can help you build a set of assumptions with which you can begin to predict specifics about that person’s personality and background. The next step is to go fishing for revelations about your subject’s life.

You may know next to nothing about the person in front of you, and you don’t need to—they will give you the secrets about themselves without realizing they are, if you ask questions about them in such a way that they appear to be statements. For example, if you they’re the person who has marital problems, you could say, “you’re marriage has been on your mind a lot lately, hasn’t it?” If you’re wrong about your statement, it doesn’t mean you’re not a psychic, because the statement was just a question.

Most of the time, your subjects will supply more information than necessary from these question-statements. It’s from these confessions that you learn more about your subject. To do this well you have to be a great listener, to really open yourself to all the information the subject is releasing to you, from what they say to how they move their hands. Every bit of data is vital for the would-be psychic.

Another technique is to use Barnum statements, which are named after P.T. Barnum, cofounder of the famous circus by the same name. A Barnum statement is one that applies to nearly everyone, such as: “you have a big decision to make soon.”

From these techniques and others you’ll give your subjects the impression you’ve read their mind, when in fact you’ve just appeared to, using specific methods to pull out secrets the subjects themselves have supplied.

9 Brain Habits You Didn’t Realize You Had…


Brain is certainly the most amazing part of human body. It becomes more interesting when it does not work the way you expect it should. Psychology frequently establishes our intuitions about how human mind works, but it reveals a number of surprises as well…

Although some psychology students will have heard one or two of these before, here’s a list of brain habits you probably didn’t realize you had:

1) The maximum capacity of your short-term memory is seven.

short-term memory is seven

Humans have basically three forms of memory: Sensory, Long-term and Short-term. Long-term memory is just like hard-drive space. Similarly, Short-term memory functions like a very small RAM. This Short-term memory is capable to hold only about five to nine (seven is an average) items at a time.

Retrieving information longer than this will need you to either pack it together into seven units or store it in Long-term memory. Have you observed that the most phone numbers have only seven digits?

2) The most visible color is Chartreuse.

most visible color is Chartreuse

Yellowish green, chartreuse, is naturally placed right in the middle of the frequencies of visible light. Human eyes have receptors for green, blue and red colors. Being placed in the middle, chartreuse actuates the most of these receptors to fire, making it distinct and easier to spot. For the same reason, in some metropolises, firetrucks have been modified from red to a yellowish green color to make them more visible and obvious to the eye.

3) Subconscious is smarter than you.

Subconscious is smarter than you

Subconscious is smarter than you. In other words, it is more powerful. In a recent study, a square was attributed to a location on a computer screen through a complex pattern. After watching it out, people began to get results better than the chance of recognizing where the square would crop up next. However, when they were inquired to consciously find out the pattern, even given a few hours, nobody really did it!

4) There are two nervous systems.

There are two nervous systems

We have two sets of nervous systems. One controls excitation, while the other controls inhibition. If you hold out your hand, you might observe minor tremors. This is actually stimulated by slight, random differences in the amount each of the two systems are firing.

5) Brain is exceptionally bad at probability.

Brain is exceptionally bad at probability

Your high-school math teacher might have told you about this one. Here what’s interesting isn’t that your brain is bad at probability. But how? In one study, recipients were asked:

Jessica is 31 years old, single, candid, and very promising. She graduated in philosophy. As a student, she was anxious about discrimination issues and social justice, and also took part in anti-nuclear demonstrations.

Assign a rank to the following statements from most probable to least probable: Jessica is a teacher in an elementary school.

  1. Jessica works in a bookstore and takes Yoga classes.
  2. Jessica is active in the feminist movement.
  3. Jessica is a psychiatric social worker.
  4. Jessica is a member of the League of Women Voters.
  5. Jessica is a bank teller.
  6. Jessica is an insurance salesperson.
  7. Jessica is a bank teller and is active in the feminist movement.

Nearly 90% of students responded that #7 was more probable than #5. This is despite the fact that to be a bank teller and in the feminist movement is entirely contained within the set of #5 (just being a bank teller). It is observable that our minds like to think more details make events more probable, not less.

6) Memory isn’t great either.

Memory isn’t great either

Research has revealed that people are highly probable to misremember past events. Even worse, it is quite easy to suggest a memory that never happened. Due to this fact, so-called “repressed” memories should be given a lot of consideration. It is extremely easier to suggest a memory of a situation that never encountered, than it is to recover one that actually did.

7) Depth is perceivable with one eye.

Depth is perceivable with one eye

It’s not quite true that depth perception is totally the result of having two eyes. Binocular vision does help in making a three-dimensional image. Still, most of your capability to perceive depth comes from inside your brain. It has been wired to look at angles and proportions to measure distance.

If you needed two eyes to perceive depth, then most optical illusions wouldn’t work and it would be extremely difficult to gather information from two-dimensional images. Not to mention a great number of one-eyed pirates walking overboard.

8 ) Long-term memory closes up during sleep.

Long-term memory closes up during sleep

The components of the brain that carry information to Long-term memory turn off while sleeping. For the same reason, dreams quickly fade out after you wake up. Although you may have quite a few dreams in a night, they aren’t being memorialized into Long-term memory. Normally only the fragments of a dream left in Short-term memory have a possibility to be converted after you wake up.

9) The Brain has an amazing instant playback feature.

Brain has an amazing instant playback feature

The last form of memory, i.e. Sensory memory is actually your brain’s equivalent to an instant playback feature. Functioning for both your vision and hearing, your thalamus can resend signals a few seconds after they were originally sent.

Let’s suppose being at a party and overhearing someone call your name. Often you can recall what they said even if you were concentrating on another conversation. This is because your sensory memory re-sends the signals when it feels something important, such as your name. If you missed this form of memory, activities such as multitasking or taking notes from a speaker would not be practicable for you.

If you’re supposed to repeat something you just said because the other person wasn’t hearing, just wait for a few seconds. Often they can replay the message in their head and cause to a reaction.
