Whether we’re assigned a learning task or choose to follow it, those subjects that interest us are always easier to comprehend, assimilate and remember over a long time. In this context, interest is actually another word for curiosity and a new research found that it is an important factor for effective learning. The team at University […]
Neuroscientists at University of Buffalo have identified a sleep-promoting circuit inside the brainstem or the primitive part of the brain, whose activity appears to be both necessary and sufficient to produce deep sleep. This is only the second ‘sleep node’ in the mammalian brain that was identified to serve this function. To demonstrate the sleep […]
A Chinese woman has shocked doctors when it was revealed that she reached 24 years without having a cerebellum. It is not the first time a person was living fine without having a cerebellum, but she entered an extremely select group, which only features 9 other people. The woman checked in at the Chinese PLA General Hospital […]
This musician played the violin while he was having a brain surgery. But why? This is by no means an eccentric fad, but a genuine feat of science. By playing the instrument during surgery, professional violinist Roger Frisch was able to guide his surgeons toward the segment of his brain which was misfiring, causing him […]
Marijuana has a lot of medical potential, but it can also have some negative effects, especially if taken regularly. A new study has shown that teens who consume marijuana regularly have lower IQs and exhibit slight brain abnormalities when they reach adulthood.
Recent findings suggest that our general cognitive abilities are heavily influenced by key regions of the brain involved in social functions, further strengthening the hypothesis that social abilities are primary to general intelligence and not the other way around.
Researchers at the School of Psychology, University of Vienna surveyed 13000 adults from Austria and Germany and found that most left-handed males are born during the winter. The difference is statistically significant, suggesting there’s a lot more at play than just chance. Namely, the findings seem to back the Geschwind-Galaburda theory of cerebral lateralization, which […]
When I was a kid, I asked, like many others, how do bees know how to make their way back to the hive – and I was told they use the Sun for guidance. But I was lied! A new study has now finally solved my childhoold dilemma: while they do use the Sun as […]
Researchers have erased and then reactivated memories in rats, profoundly impacting the animals’ reaction to past events. This is the first study ever to demonstrate the ability to selectively erase and then reactivate a memory by stimulating nerves in the brain at frequencies that strengthen synapses, the connection between neurons. The Eternal Sunshine of the Spotless […]
A mouse might not look like the smartest animal, but however modest its cortex may seem it’s still 9,000 times faster than a personal computer simulation of its functions. Not only that, but it takes 40,000 times more power to run – energy efficiency being, in fact, the true benchmark that needs to be considered when […]
A common brain myth is that creative people, like artists, use their right part of the brain more, while the left part of the brain is more active in rational people. This has been debunked many times, and a few searchers on Google will satisfy your curiosity, if you think otherwise. It’s true, however, that […]
Prepare to enter the era of Big Neuroscience. For the past decade or so, billions worth of research has provided some of the most tantalizing clues about how the human brain works, and consequently we, as human beings, reason. There are millions of people in the world suffering from dreaded neurodegenerative diseases, like Alzheimer’s or […]
The most basic fabric of civilization was woven on the principles of moral judgement, that is to say serving the interests of the community and others, instead of merely following self-interest at large. This is why some believe, arguably or not, that religion was a key civilizing factor since it laid out a moral workbook. […]
A potentially game changing drug developed by scientists at Karolinska Institutet and Uppsala University infiltrates the cells from glioblastoma, the most aggressive type of brain tumor, and causes them to literally explode. Trials so far have been made only on mice whose tumor growth was reversed and survival was prolonged considerably. Glioblastoma multiforme (GBM) is […]
It’s a little out of this world – a psychology graduate student at the University of Ottawa says she can voluntarily enter an out-of-body experience. While scientists are generally skeptical when it comes to this kind of claims, they were thrilled by the possibility to scan her brain during the experience – and the results […]
In most of the world, winter long ground to a halt to make way for more harmonious seasons. Still, these are still tense times for your health, as one day can be sunny, the other murky and cold. A lot of people get snuffed and catch a cold. While you’re tucked inside your sheets, blowing […]
If you’ve ever had a nice fuzzy feeling whenever you heard the voice of a loved one, then, you’re not alone. If somebody’s ever told you that ‘we need to talk’ and out of their tone you understood that something’s bad, then again, you’re not alone. A new study has shown that dogs have an […]
An imbalance in chloride ions during a fetus’s development is one of the factors for autism, study shows. Some children today show clear symptoms of autism only a year or more after birth, such as the impossibility to focus on eye contact or poor language development. The study made by neuroscientist Yehezkel Ben-Ari and his […]
Human embryonic stem cells can be induced into forming a developing brain tissue. The brain development process represents one of the most specific processes; during it, neuroepithelium, formed as a flat sheet by the nervous system, grows on the exterior layer of the embryo, after which it folds in to create a neural tube giving […]
What evolutionary traits helped humans become the dominant species on Earth? Our dexterous limbs and complex nervous system certainly played a major role, allowing human to manipulated the world and handle tools. Physicians are very interested in studying motor neural circuits to make better therapies when things go wrong, and to attain a comprehensive understanding […]
M.P., a kindergarten teacher and expert reader, was hit by a stroke and, in the aftermath, her brain underwent some irreversible transformations. It’s hard to imagine the confusion and fright the 40-year-old woman must have felt when shortly after her stroke, while in the classroom trying to read to children – her biggest source of […]
An international team of researchers believes they have found a way to reopen critical learning periods in the brain, allowing adults to learn as if they were children, even abilities thought to be restricted to early ages, such as new language learning and absolute pitch development. The drug is known as valproate or valporic acid […]
Case Western Reserve University and University of Kansas Medical Center researchers recently report they’ve devised a neural prosthetic that partially restored brain connectivity in rats whose brains were injured. Effectively, the rats regained their functional behavior and were able to perform tasks similarly to normal rats, something that otherwise wouldn’t had been possible. The research gives hope […]
A new study which involved the analysis of over 1.000 brain scans confirmed what many intuitively believed for a long time: men and women’s brains are hard wired differently. Maps of neural circuitry showed that on average women’s brains were highly connected across the left and right hemispheres, while men had better connections between the […]
The human brain is possibly the most complex entity in the Universe. It’s absolutely remarkable and beautiful to contemplate, and the things we are capable of because of our brains are outstanding. Even though most people might seem like they’re using their brains absolutely trivially the truth is the brain is incredibly complex. Let’s look […]
In the US alone there are an estimated 100 million daily coffee drinkers, each contributing to a booming $18 billion industry. Of these, 68% claim they have their first coffee within the first hour of waking up. As a coffee drinker, I find myself guilty of the same practice, but apparently this isn’t the best […]
Some people are better navigators than others, i.e. men better than women. Whether you can make your way effortlessly through the woods to reach a safe house or get seemingly lost on your way home from a different bus stop, it doesn’t make that much of a different at a sensory level. Navigation is often […]
It may not look like much, but this weird looking coal-like thing is actually a 4.000 year old preserved brain, which was “scorched and boiled in its own juices.” “The level of preservation in combination with the age is remarkable,” Frank Rühli at the University of Zurich, Switzerland explained, adding that most archaeologists simply don’t […]
Mere hours after his death in 1955, Albert Einstein‘s brain was removed, weighed and analyzed in a lab at Princeton Hospital by pathologist Thomas Stoltz Harvey. Bits of his brains were then sent to other pathologists around the country for analysis in hope that a connection between its physical attributes and the remarkable genius of […]
After they identified precise groups of cells in mice brain that induce eating and others that curb it, a team of researchers caused full mice to continue eating and hungry mice to stop eating simply by stimulating one of these areas. Their findings could aid in the development of novel drugs that target eating disorders […]
In one of Stanley Kubrick’s weirdest movies (even by Kubrick standards), “Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb (1964)“, one of the characters played by Peter Sellers is tormented by the irresistible and convulsive urge of lifting his right arm in a Nazi salute. He can’t control it, it’s […]
Every time we’re engaged in a certain action, the sounds we produce while walking, eating, even playing music are tuned down a notch in volume by the brain. For instance, during a conversation your voice will be perceived as quieter than it actually is in reality, since our brain want to receive clearer the information […]
Most medical research looking to identify the mechanisms of a disease or test treatments rely on animal models. While very useful, mice for instance (a favorite lab pet for researchers) do not have nearly the same brain structure or genes as humans. Even if some genes and proteins scientists target are the same both in […]
In a mind-boggling and, frankly, a bit frightening breakthrough, researchers at University of Washington have devised a brain-to-brain interface that for the first time has allowed the remote exchange of information between two human brains. The test that demonstrated the technology, although simple in nature, shows of a powerful display of force. One researcher (human brain […]
Farmers, with the help of researchers in the field, have been desperately trying to develop new insecticides that can ward off pests looking to claim their crops. These products work with a varying degree of effectiveness. For one, the insect pests tend to develop tolerance and new solutions have to be developed, and of course […]
It’s clear that humans are now, more than ever, a driving force in evolutionary biology. Early domestication efforts through breeding and training have changed some species to the point that they’ve grown to be as we wanted them to become. The effects of climate change, a great part of which is anthropogenic, actually influence animals […]
Scientists have striven for years to comprehend the complicated neurological mechanisms that underline the human brain and consciousness. Besides the philosophical aspects of such a quest (how we do think? what is consciousness born?), a better understanding of the human brain will help solve a number of medical issues that currently plague the human brain. […]
It’s the early 1950s, and some strange experiments are going on at Tulane University in Louisiana. Well, maybe not weird, but definitely pushing the limits of neurophysiological knowledge one step further. Dr. Robert G. Heath is at the forefront of these experiments, and he found that he can manipulate both the pleasure and pain centers […]
A single molecular switch can make the transition between the active, malleable brain of an adolescent and the mature, stable brain of an adult; yep, a single gene can turn us back to the childlike curiosity we exhibit as adolescents. Researchers have known for quite a while that adolescent brains are typically more malleable (or […]
In an incredible feat of neuroscience and communications, researchers at Duke University School of Medicine formed a link between pairs of rats by electronically linking their brains. As such, the rats could exchange motor and tactile information between each other. In one particular case, the experiment showed that a pair of linked rats – one rat […]
A new study published by MIT revealed, for the first time, what happens inside the brain when you go unconscious. By monitoring the patients’ brain as they were given anesthetics, the researchers were able to identify a distinctive brain activity pattern that occurred as unconsciousness settles in. The pattern can be characterized by a breakdown […]
For scientists, the most common method of assessing an animal’s intelligence is by looking at its relative brain size, with respect to its body size. The human brain, for instance, is small compared to other animal’s brain, however it’s exceptionally large when considering our body mass. A new study, which analyzed the relative brain size […]
Scientists at University of Sydney have been studying for the past few years one of the most peculiar events in nature. It seems that a living slime, no less, no more, is capable of reading information and remembering its past “steps” acting on some sort of external memory, this despite the fact that it has no […]
Australian scientists say that persons with psychopathic tendencies could be spotted through a smell test, correlated with a psychological questionnaire. The link doesn’t lye in the actual odor emanated by a potentially psychopathic person, though, but rather in their sense of smell. The study conducted by Mehmet Mahmut and Richard Stevenson, from Macquarie University, is based on […]
After the most recognized physics figure in the world, Albert Einstein, past away on April 18, 1955, the whole world was left in shock, seeing how he was even by then considered the most famous physicist in history. His dying wish was that of being cremated, however an eccentric physician by the name of Thomas Harvey, a […]
Someone whose been driving for 20 years, let’s say, in the United States and somehow ends up driving a car in the UK will be in a lot of trouble. Going from right side driving to left side driving, or vice versa, will bewilder just about anyone, and if you’ve gone through such an experience […]
The most complex object on Earth is the human brain. However, even though it’s intertwined by billions of nerve fibers almost in a chaotic fashion, scientists who have used sophisticated mathematical analysis of advanced imaging data found that the neural pathways that carry electrical signals through the brain are arranged in a very simple manner, resembling […]
In the not so distant future, scientists could be able to eavesdrop on a patient’s inner monologues or communicate with those who cannot speak, thanks to a breakthrough made by researchers from the University of California, Berkeley. They have astonishingly managed to crack the ‘code’ of a brain wave by decoding electrical activity in a […]
What if you could increase your ability to remember with a pill? This may not be an idea just for science fiction novels. Scientists have discovered a method that could strengthen long-term memories. A protein called PKR functions to maintain a relatively low level of excitability by enhancing GABA synaptic transmission. GABA is an inhibitory […]
The brain learns basically by shifting between different strengths of its synapses, as a response to different stimuli – that much is clear. However, recently, a team of UCLA scientists have shattered the common belief about the mechanism of learning, showing that the brain learns rhythmically, and that there is an optimal ‘rhythm’, or frequency, […]
