Smarter Brains Run on Sparsely Connected Neurons

Smarter Brains Run on Sparsely Connected Neurons

Summary: A new study reveals the brains of higher IQ people tend to have leaner, yet more efficient neural connections. Researchers report, the more intelligent a person, the fewer dendrites they have in their cerebral cortex.

The more intelligent a person, the fewer connections there are between the neurons in his cerebral cortex. This is the result of a study conducted by neuroscientists working with Dr Erhan Genç and Christoph Fraenz at Ruhr-Universität Bochum; the study was performed using a specific neuroimaging technique that provides insights into the wiring of the brain on a microstructural level.

Together with colleagues from the University of New Mexico in Albuquerque, Humboldt University of Berlin and the Lovelace Biomedical and Environmental Research Institute in Albuquerque, the team from the biopsychology research unit in Bochum published their report in the journal Nature Communications on May 15, 2018.

Intelligence is determined by the number of dendrites

The researchers analysed the brains of 259 men and women using neurite orientation dispersion and density imaging. This method enabled them to measure the amount of dendrites in the cerebral cortex, i.e. extensions of nerve cells that are used by the cells to communicate with each other. In addition, all participants completed an IQ test. Subsequently, the researchers associated the gathered data with each other and found out: the more intelligent a person, the fewer dendrites there are in their cerebral cortex.

The Unified Field and the Quantum Nature of Consciousness

The Unified Field and the Quantum Nature of Consciousness

We’re getting closer to incorporate consciousness as an integral part of the scientific picture of the “physical world”. Not only celebrated physicists of the 20th century such as Max Plank, John Wheeler, David Bohm, Niel Bohr, Erwin Schrödinger argued that consciousness is a fundamental property of our Universe but the new pleiad of scientists such as John Hagelin, Sir Roger Penrose, Stuart Hameroff, Guilio Tononi, Christof Koch, Donald Hoffman, Robert Lanza embarked on their quest to put consciousness on the new solid scientific footing and dimensionality.

Naturalism with its Newtonian mechanics and classical interpretation of reality is valid only within its domain of applicability, namely human perceptual reality, whereas quantum theory paints a drastically different picture. As Max Plank once said: “Science cannot solve the ultimate mystery of nature. And that is because, in the last analysis, we ourselves are a part of the mystery that we are trying to solve.” Nothing is real for us until perceived, and all we know is our own inner experience. That’s why scientists have to deal with the mystery of how there can be anything but a first-person reality. No matter how you slice it, everything leads back to the conscious observer.

Why Great Employees Leave “Great Cultures”

Why Great Employees Leave “Great Cultures”

“We have a great culture.” We have all heard it. We have all said it. But what does that mean?

Ping-Pong tables, free meals, and beer on tap? No.

Yoga, CrossFit classes, and massage chairs? I so need that, but no.

The promise of being part of a hip, equity-incentivized, fast growing team? Closer, but still no.

Culture is often referred to as “the way things are done around here.” But to be useful, we need to get more specific than that. I’ve been working in HR for over twenty years, and the best companies I’ve worked with have recognized that there are three elements to a culture: behaviors, systems, and practices, all guided by an overarching set of values. A great culture is what you get when all three of these are aligned, and line up with the organization’s espoused values. When gaps start to appear, that’s when you start to see problems — and see great employees leave.

Why Talented People Don’t Use Their Strengths

Why Talented People Don’t Use Their Strengths

 

If you watched the Super Bowl a few months ago, you probably saw the coaches talking to each other over headsets during the game. What you didn’t know is that during the 2016 season, the NFL made major league-wide improvements to its radio frequency technology, both to prevent interference from media using the same frequency and to prevent tampering. This was a development led by John Cave, VP of football technology at the National Football League. It’s been incredibly helpful to the coaches. But it might never have been built, or at least Cave wouldn’t have built it, had it not been for his boss, Michelle McKenna-Doyle, CIO of the NFL.

When McKenna-Doyle was hired, she observed that a number of her people were struggling, but not because they weren’t talented — because they weren’t in roles suited to their strengths. After doing a deep analysis, she started having people switch jobs. For many, this reshuffling was initially unwelcome and downright uncomfortable. Such was the case with Cave.

The Difference Between Human And Dolphin Brains

​The difference between human and dolphin brains

There are strong possibilities that cetaceans can project an auditory image that replicates a sonar message that they may receive. So a dolphin wishing to convey an image of a fish to another dolphin can literally send the image of the fish to the other animal – it’s similar to a Star Wars hologram, or sending an image via Facebook Messenger.

Even with sleep cycles, cetaceans do it differently. Captive dolphins have been observed to allow half their brain to sleep at any given time, whilst the other part will stay wide awake and aware. This is likely due to the ocean environment – with few places to hide this keeps the dolphins aware at all times. Cetaceans are also considered to be incredible planners

Brains of Young People with Severe Behavioral Problems ‘Wired’ Differently

Brains of Young People with Severe Behavioral Problems ‘Wired’ Differently

 

Research published today has revealed new clues which might help explain why young people with the most severe forms of antisocial behaviour struggle to control and regulate their emotions, and might be more susceptible to developing anxiety or depression as a result.

The study, published in the journal Social Cognitive and Affective Neuroscience, used neuroimaging methods to investigate young people with the condition ‘Conduct Disorder’ – typified by symptoms that range from lying and truancy, through to physical violence and weapon use at its more extreme end.

Researchers from the universities of Bath (UK), Cambridge (UK) and the California Institute of Technology (USA) wanted to understand more about the wiring of the brain in adolescents with Conduct Disorder, and link connectivity to the severity of Conduct Disorder and ‘psychopathic traits’ – the term used to define deficits in guilt, remorse and empathy.

Wired differently?

Through functional MRI scans of young people with Conduct Disorder as well as typically-developing teens, the team analysed the amygdala – a key part of the brain involved in understanding others’ emotions – and how it communicates with other parts of the brain.

7 Strengths of Deep Souls: The Thinkers We Need But Rarely Understand

7 Strengths of Deep Souls: The Thinkers We Need But Rarely Understand

Synopsis

The underlying traits that fuel deep soul strengths are universal characteristics of creative thinking. Research shows that nearly all of us have an intense combination of these strengths in early childhood, but they get dulled over time–especially during our school years. Deep souls, however, have resisted this dulling. They can’t help it. The intensity of their ability to think differently cannot and will not be stopped.

He reads slowly but remembers everything he’s read, using this random knowledge to make unusual connections.

She’s the person I go to who always has a new perspective, a new way of looking at a problem. She helps me get out of a thinking rut.
