brain是什么意思？

When we acquire new information, the brain automatically tries to incorporate ( ' , 合并) it within existing information by forming associations.

The brain is a seemingly endless library, whose shelves house our most precious memories as well as our lifetime's knowledge.

Normal forgetting may even be a safety mechanism to ensure our brain doesn't become too full.

Needless to say, people like Veiseh are of great interest to neuroscientists ( ' , 神经科学专家) hoping to understand the way the brain records our lives.

It can enlarge our brain capacity.

Instead of just crowding in, old information is sometimes pushed out of the brain for new memories to form.

In a sense, forgetting is our brain's way of sorting memories, so the most relevant memories are ready for retrieval.

But is there a point where it reaches capacity?The answer is no, because brains are more sophisticated than that.

But in a new study, researchers demonstrated for the first time how this effect occurs in the brain.

A young woman sought explanation from a brain scientist when she noticed her unusual memory.

Some show up ready, but many do not at this critical time when young brains are developing rapidly.

Declining mental function is often seen as a problem of old age, but certain aspects of brain function actually begin their decline in young adulthood, a new study suggests.

Informing students about the brain as a learning machine is a good strategy to enhance their motivation for learning.

In the growth mind-set classes, students read and discussed an article entitled You Can Grow Your Brain.

From such instruction, many students began to see themselves as agents of their own brain development.

According to a new study from Cornell University's Food and Brand Lab, small nonfood rewards—like the toys in McDonald's Happy Meals—stimulate the same reward centers in the brain as food does.

They were taught that the brain is like a muscle that gets stronger with use and that learning prompts the brain to grow new connections.

Behavioral genetics has made important contributions to the biological revolution, providing information about the extent to which biology influences mind, brain and behavior.

For example, social contact can boost development of the brain and immune system, leading to better health and less chance of depression later in life

"There's a mountain of evidence 34 proving the importance of sex influences at all levels of brain function," he told The Seattle times.

A review of 54 studies found that eating breakfast can improve memory, though the effects on other brain functions were inconclusive.

According to a new study from Cornell University's Food and BrandLab, small nonfood rewards—like the toys in McDonald's Happy Meals—stimulate the same reward centers in the brain as food does.

Activities like knitting and crocheting make it harder for the brain to register pain signals.

An entertaining way of enhancing your analytical skills is to engage them by playing brain games.

Breakfast is also associated with improved brain function, including concentration and language use.

Changes in brain cells can affect communication between different regions of the brain.

Daphna Joel, who led the study, said her research found that while there are some gender-based similarities, many different types of brain can't always be distinguished by gender.

Despite having a brain no bigger than the tip of your index finger, pigeons have a very impressive visual memory.

In the study, Tel Aviv University researchers searched for sex differences throughout the entire human brain.

It's a hobby that I've stuck with and it continues to help me cope with stress at work, provide a sense of order in hectic days, and allow my brain time to solve problems.

Larry Cahill, an American neuroscientist, said the study is an important addition to a growing body of research questioning traditional beliefs about gender and brain function.

Needless to say, people like Veiseh are of great interest to neuroscientists hoping to understand the way the brain records our lives.

Perhaps most exciting is research that suggests that crafts like knitting and crocheting may help to keep off a decline in brain function with age.

Physical activity can improve blood flow to the brain, fueling memory, attention and creativity, which are essential to learning.

Physical activity does the body good, and there's growing evidence that it helps the brain too.

She suggested that the brain can process just so much at once, and that activities like knitting and crocheting make it harder for the brain to register pain signals.

The frozen oranges and apples are a little cheaper, and fruits are really good for the brain.

The researchers speculate that craft activities promote the development of nerve pathways in the brain that help to maintain cognitive health.

They were taught that the brain is like a muscle that gets stronger with use and that learning prompts the brain to grow new connections.

When we acquire new information, the brain automatically tries to incorporate it within existing information by forming associations.

While the "average" male and "average" female brains were slightly different, you couldn't tell it by looking at individual brain scans.

To reduce or avoid it, researchers have examined the effect of smoking, diet, brain-challenging games, exercise and other strategies.

But by 2014, the death rate from Alzheimer’s Disease for this age group have more than doubled, increasing from 3.8% to 8.5%, making the progressive brain disease the second leading cause of death for centenarians.

But in practice, our brain discounts the risks — and benefits — associated with issues that lie some way ahead.

Are people suffering from gadget overload? Are they exhausted by the consumer equivalent of the brain fatigue—information overload—that is caused by constant updates of devices and online media?As you are probably aware, the latest job markets news isn’t good: Unemployment is still more than 9 percent, and new job growth has fallen close to zero.

The Uses of Difficulty The brain likes a challenge—and putting a few obstacles in its way may well boost its creativity

As the brain attempts to force the unsteady hand to do its bidding, the tension between the two results in a more compressed, psychologically denser expression

Our brains respond better to difficulty than we imagine

One's brain becomes sharp when it is activated.

Their brains become both calmer and sharper.

After a long period, alcoholism can deteriorate the liver, the brain and other parts of the body.

They believe that the nerve endings in the left side of the brain develop faster in girls than in boys, and it is this side of the brain that strongly influences an individual's ability to use language and remember things.

The two sides of their brain develop simultaneously.

According to a report from the Harvard School of Public Health, many everyday products, including some bug sprays and cleaning fluids, could lead to an increased risk of brain and behavioral disorders in children.

Because children's brain and behavioral disorders, like hyperactivity and lower grades, can also be linked to social and genetic factors, it's tough to pin them on exposure to specific chemicals with solid 33 statistical evidence, which is what the EPA re

But in practice, our brain discounts the risks —and benefits — associated with issues that lie some way ahead.

But surely everyone reading this has had times when you lie in bed for hours, unable to fall asleep because your brain is thinking about work.

For example, dolphins, as well as other marine animals, shut down one hemisphere of the brain when they go to sleep.

Half of your brain stays alert and prepared for danger when you sleep in a new place, a study has revealed.

He points to a classic 2004 study in which psychologists at Dartmouth College and Harvard University used functional MRI to track brain activity in 17 young men as they listened to descriptions of people while concentrating on either socially relevant cue

If after work you lie around on your bed and get irritated by political commentary on your phone or get stressed thinking about decisions about how to renovate your home, your brain has not received a break from high mental arousal states.

In a 2011 study, Steinberg and his colleagues turned to functional MRI to investigate how the presence of peers affects the activity in the adolescent brain.

In studies, he gave subjects a chance to deceive for monetary gain while examining their brains in a functional Mri machine, which maps blood flow to active parts of the brain.

It was specifically observed that the left side of the brain was more active during deep sleep.

Moreover, understanding the brain is not the same as understanding the mind.

Now, a company in Massachusetts says that by using magnetic brain scans, they can determine with 97% accuracy whether someone is telling the truth.

Recent research has also shown that indulging in a high-fat and high-sugar diet may have negative effects on your brain, causing learning and memory deficits.

Researchers from Brown University found that a network in the left hemisphere of the brain "remained more active" than the network in the right side of the brain.

So, while there may be insights to be gained from matching behavior to brain activity, those insights will I not necessarily lead to justice in a court of law.

Some previous studies have suggested that challenging your brain with mentally stimulating activities might help.

The amygdala is a crucial part of the brain that produces fear, anxiety and emotional responses including that sinking, guilty feeling you get when you lie.

The developing brain, the report says, is particularly vulnerable to the toxic effects of certain chemicals these products may contain, and the damage they cause can be permanent.

The researchers believe this is the first time that the "first night- effect" of different brain states has been identified in humans.

The researchers explained that the study demonstrated when we are in a novel environment the brain partly remains alert so that humans can defend themselves against any potential danger.

These differences may elicit different brain responses.

They should also be sceptical of the growing tendency to try to reduce all human traits and actions to the level of brain activity.

To do this successfully, their brain prompts them to think and even obsess about others.

without keeping the brain active while sleeping, they would probably drown.
