Brain Lateralization and its Effects on Language Facility and Brain Functions

So how it fits into our family tree is not clear. Human brains are different mostly because of structures that have to do with language and social skills. But in modern humans, the frontal lobes of the brain have expanded toward the back and sides, creating structures called the frontal opercula. The best way to answer this question is to build a better picture that draws in many kinds of evidence. We have debated how smart Neanderthals were for years—and now that scientists are bringing together more evidence from archaeology, from pigments, from the brain and genetics, it is clear that they were not so different from us. In humans, that asymmetry is probably associated with language-processing and producing centers of our left hemispheres being more developed. That asymmetry might, as a side effect, be the reason most of us tend to have a dominant right hand.

Are you right-brained or left-brained?

Your left brain has a bigger ego than your right brain Psychologists have used an inventive combination of techniques to show that the left half of the brain has more self-esteem than the right half. The finding is consistent with earlier research showing that the left hemisphere is associated more with positive, approach-related emotions, whereas the right hemisphere is associated more with negative emotions. This compares how readily participants associate themselves or other people with positive words like ‘capable’ and negative words like ‘boring’.

Share via Print Recent research published in the journal Brain and Cognition finds that people can boost the number and quality of their original ideas when they increase the interaction between the brain’s right and left hemispheres. Christie Nicholson reports Full Transcript The formula for creative thinking is pretty elusive, but scientists have a few evidence-based clues. Scientists say that it is the fixed rules of the left hemisphere that keeps a logical check on the broad brainstorming of the right hemisphere.

So you wind up with super creative, yet practical, ideas. In fact, a study published this week in the journal Brain and Cognition shows that when you boost the level of communication between the right and left hemispheres your creativity increases. Sixty-two subjects performed a creativity task, where they had to come up with as many alternate uses for common objects like, a paper clip, pencil, shoe, etc. After this initial task researchers asked subjects to move their eyes to follow a target as it moved horizontally left to right for 30 seconds.

This exercise is thought to increase the cross-talk between the hemispheres. Then the subjects completed the creative task again.

A new study suggests that commercial brain training computer games have no effect on cognitive function. Researchers at the University of Pennsylvania found that they also have no effect on decision-making. They hoped commercial brain training regimes could reduce individuals’ propensity to make risky or impulsive choices. Dr Lerman’s prior work had shown that engagement of brain circuits involved in self-control predicts whether people can refrain from smoking.

They also knew that this behaviour is likely mediated by a set of brain structures in the dorsolateral prefrontal area of the brain that have been associated with performance on the executive function tasks, like the ones in the Lumosity battery. One group was asked to follow a brain training regimen, performing the executive function games for 30 minutes a day, five days a week for ten weeks.

There have been several theories over the years about why some people favour their left hand. A study from last year has shown that it might be nothing to do with your brain. Rather, it could be determined by your spinal cord while you are in the womb. Left-handed people haven’t always been treated very well throughout history. In fact, the word “sinister” derives from “left” or “left-hand.

It’s down to the spinal cord — not the brain Research since the s has shown that our preference for being left or right-handed is probably determined in the womb before we are born, as early as the eighth week of pregnancy, according to ultrasound scans.

The human brain is amazing. From the s right up to the s, the museum was the site of the Central State Hospital, a psychiatric ward that performed its fair share of autopsies. After the bodies were cut up, the brains were jarred and locked away in a warehouse—a warehouse Charles later slipped into repeatedly. Neither Charles nor his eBay middleman had the brains to remove the museum labels from the jars.

Science News Why anxiety makes people veer to the left Scientists have discovered that feeling anxious makes people very to the left because their right hand side of the brain is so active. Find yourself veering to the left as you walk? Scientists have discovered that feeling anxious makes people begin veering to the left because their right hand side of the brain is so active.

People who blindfolded and asked to walk in a straight line across a room towards a previously seen target all veered to the left if they were more anxious,. Getty Images A separate study also found that people perform more badly in tests if they know they are being watched, particularly if they face criticism from their audience. Experts have been able to pinpoint the area of the brain that causes performance mishaps in an experiment using functional magnetic resonance neuroimaging fMRI.

A brainteaser is a type of riddle that makes one think outside the box. Some brainteasers are easy, some are a little harder, and some can really make you ponder for a while. Often, when you finally hear the answer, you feel ignorant or silly, because it should have been obvious to you.

Signing your name or scribbling a grocery list may seem a simple, mundane activity. No wonder, then, that accidents and diseases that change the brain leave important calling cards in our handwriting. Handwriting expert Marc J. Courtesy of Marc J. Seifer Written language is a further evolution of the highly complex human capability for spoken language that probably goes back at least , years, to the time when our distant ancestors were just beginning to make tools.

Because it is both neurological and psychological, handwriting is a window into the complex interplay of brain and mind. Conversely, studying handwriting may give us important clues to how and where a brain is malfunctioning.

In a society where gender equality is often put to the test in the workplace, in relationship clashes and marriage dynamics, has anyone bothered to think about what makes males different from females? The answer, of course, has to do with more than just the psychological profile but something deeper—the biological makeup of the brain itself. First, males have larger brains than females. A larger brain does a better job of controlling the muscle groups which are more extensive in males than in females.
