Researchers Crack the Brain's Facial-Recognition Code. Our brains have evolved to recognize and remember faces.

Researchers Crack the Brain's Facial-Recognition Code

As infants, one of the first things we learn is to look at the faces of those around us, respond to eye contact and mimic facial expressions. First hint of 'life after death' in biggest ever scientific study. Scientists have discovered how to 'delete' unwanted memories. Men lose their minds speaking to pretty women. Alpha, Beta, Theta Brainwaves - Understanding Our Brain. Magnets Can Improve Your Memory. Magnets could eventually be used to compensate for memory problems caused by dementia.

Magnets Can Improve Your Memory

Your brain is unique – here's how it could be used as the ultimate security password. Biometrics – technology that can recognise individuals based on physical and behavioural traits such as their faces, voices or fingerprints – are becoming increasingly important to combat financial fraud and security threats.

Your brain is unique – here's how it could be used as the ultimate security password

This is because traditional approaches, such as those based on PIN numbers or passwords, are proving too easily compromised. For example, Barclays has introduced TouchID, whereby customers can log onto internet banking using fingerprint scanners on mobile phones. The Power of Overlearning. When you want to learn something new, you practice.

The Power of Overlearning

Once you get the hang of it, you can hopefully do what you learned—whether it’s parallel parking or standing backflips—on the next day, and the next. If not, you fall back to stage one and practice some more. But your brain may have a shortcut that helps you lock in learning. Instead of practicing until you’re decent at something and then taking a siesta, practicing just a little longer could be the fast track to solidifying a skill. How Thinking Works: 10 Brilliant Cognitive Psychology Studies Everyone Should Know. How experts think, the power of framing, the miracle of attention, the weird world of cognitive biases and more… Fifty years ago there was a revolution in psychology which changed the way we think about the mind.

How Thinking Works: 10 Brilliant Cognitive Psychology Studies Everyone Should Know

The ‘cognitive revolution’ inspired psychologists to start thinking of the mind as a kind of organic computer, rather than as an impenetrable black box which would never be understood. This metaphor has motivated psychologists to investigate the software central to our everyday functioning, opening the way to insights into how we think, reason, learn, remember and produce language. Brain Plasticity: How Adult Born Neurons Get Wired – Neuroscience News. Summary: Researchers report adult neurogenesis not only helps increase the number of cells in a neural network, it also promotes plasticity in the existing network.

Additionally, they have identified the role the Bax gene plays in synaptic pruning. Source: University of Alabama at Birmingham. One goal in neurobiology is to understand how the flow of electrical signals through brain circuits gives rise to perception, action, thought, learning and memories. 7 Signs of Intelligence That Suggest You Are Smarter Than Average. Surprising signs of intelligence include a tendency towards mental illness, being prone to worry, sleeping late and more… 1.

7 Signs of Intelligence That Suggest You Are Smarter Than Average

Mental illness Disorders of mood could be the price some people pay for high intelligence, recent research finds. Psychologists have found that higher childhood IQ is linked to features of bipolar disorder in young adulthood. The research adds fuel to the debate over the connection between intelligence, creativity and mental health issues. Other studies now suggest a link between intelligence and mental illness that may go back into our evolutionary past. The increased intelligence of Homo sapiens was originally a result of gene mutations. The cost of these gene mutations, however, may have been an increase in mental illness (Nithianantharajah et al., 2012). The Best Sleep Position For Clearing The Brain of Waste. On your side, face-up or face-down?

The Best Sleep Position For Clearing The Brain of Waste

The position which best clears metabolic waste from your brain at night. Sleeping on your side removes waste from the brain most efficiently, a new study finds. As a result, sleeping in a lateral position may help reduce the chance of developing Alzheimer’s and other neurological diseases. Some People's Brains Are Wired for Languages. Babies' ability to soak up language makes them the envy of adult learners everywhere.

Some People's Brains Are Wired for Languages

Still, some grown-ups can acquire new tongues with surprising ease. Now some studies suggest it is possible to predict a person's language-learning abilities from his or her brain structure or activity—results that may eventually be used to help even the most linguistically challenged succeed. In one study, published in 2015 in the Journal of Neurolinguistics, a team of researchers looked at the structure of neuron fibers in white matter in 22 beginning Mandarin students. Sending Text Messages On Your Smartphone Changes The Rhythm Of Your Brain Waves. The ability to multitask is valued in our society as we juggle deadlines, projects, and multiple demands.

Sending Text Messages On Your Smartphone Changes The Rhythm Of Your Brain Waves

The pressure to increase our productivity tempts us to use our smartphones, even when we're behind the wheel. A new study shows there’s another reason to resist the temptation to text while driving. "We think active text messaging actually creates an electrophysiologic potential that's unique to some type of personal electronic device," said Dr. Researchers think they know how to make your brain learn like a kid again. Kids have amazing brains. They can pick up two languages in early childhood just as easily as they can learn one. Early childhood also seems to be the key time period when musical training makes it much easier to acquire the skill known as perfect or absolute pitch.

And that's not all - kids and teens are able to learn certain skills and abilities much more quickly than most adults. Here Is What The Internet Is Doing To Human Memory. More ammunition for those claiming that the internet is making us stupid. Using the internet to look up facts makes us more reliant on it in the future, new research finds. The more times people look up facts online, the less they prefer to rely on their own memories for even the simplest questions. Psychologists have called this ‘cognitive offloading’. Effectively the internet is taking over from human memory. Dr Benjamin Storm, the study’s first author, said: Sex differences in neural and behavioral signatures of cooperation revealed by fNIRS hyperscanning : Scientific Reports.

Differences in male, female brain activity found when it comes to cooperation. Studies have long shown that when faced with a problem that must be solved by cooperating with others, males and females approach the task differently. Now, researchers at the Stanford University School of Medicine have discovered how those differences are reflected in brain activity. When the researchers asked people to cooperate with a partner and then tracked the brain activity of both participants, they found that males and females had different patterns of brain activity.

The new findings, to be published online June 8 in Scientific Reports, could offer some clues into how cooperative behavior may have evolved differently between males and females, and could eventually help researchers develop new ways to enhance cooperative behavior. Early brain connections key to reading: Pathways that exist before kids learn to read may determine development of brain's word recognition area.

A new study from MIT reveals that a brain region dedicated to reading has connections for that skill even before children learn to read. By scanning the brains of children before and after they learned to read, the researchers found that they could predict the precise location where each child's visual word form area (VWFA) would develop, based on the connections of that region to other parts of the brain. Neuroscientists have long wondered why the brain has a region exclusively dedicated to reading -- a skill that is unique to humans and only developed about 5,400 years ago, which is not enough time for evolution to have reshaped the brain for that specific task.

The new study suggests that the VWFA, located in an area that receives visual input, has pre-existing connections to brain regions associated with language processing, making it ideally suited to become devoted to reading. Saygin is the lead author of the study, which appears in the Aug. 8 issue of Nature Neuroscience. More evidence that male and female brains are wired differently.

While measuring brain activity with magnetic resonance imaging during blood pressure trials, UCLA researchers found that men and women had opposite responses in the right front of the insular cortex, a part of the brain integral to the experience of emotions, blood pressure control and self-awareness. The insular cortex has five main parts called gyri serving different roles.

The researchers found that the blood pressure response in the front right gyrus showed an opposite pattern in men and women, with men showing a greater right-sided activation in the area while the women showed a lower response. "This is such a critical brain area and we hadn't expected to find such strong differences between men and women's brains," said Paul Macey, the study's lead author. "This region, the front-right insula, is involved with stress and keeping heart rate and blood pressure high. Regrown Brain Cells Give Blind Mice a New View. Researchers at Stanford University have coaxed brain cells involved in vision to regrow and make functional connections—helping to upend the conventional dogma that mammalian brain cells, once damaged, can never be restored.
