Your Consciousness Can Connect With the Whole Universe, Groundbreaking New Research Suggests

Posted by in categories: neuroscience, quantum physics

This latest clue about the architecture of consciousness supports a Nobel-Prize winner’s theory about how quantum physics works in your brain.

Men have a daily hormone cycle — and it’s synced to their brains shrinking from morning to night

Posted by in category: neuroscience

A month-long study of a man’s brain revealed that its volume consistently shrunk over the course of each day and then reset overnight.

A Person’s Intelligence Limits their Computer Proficiency More than Previously Thought, say Researchers

Posted by in categories: computing, neuroscience

A new study has found that intelligence, in the form of general cognitive abilities such as perception, thinking and remembering, is more important than hitherto thought at predicting a person’s ability to complete common tasks with a PC. The study was published in the International Journal of Human-Computer Studies in August 2024.

“Our research findings are the first clear proof that cognitive abilities have a significant, independent and wide-ranging effect on people’s ability to use a computer. Contrary to what was previously thought, cognitive abilities are as important as previous experience of computer use,” says Aalto University’s Professor Antti Oulasvirta, who studied human-computer interaction extensively with his team.

The findings have implications for digital equality, say the researchers, because everyday user interfaces have simply become too complex to use. Practice alone is no longer enough, with intelligence becoming an equally critical factor in predicting performance in computer tasks.

Pain relief from the placebo effect may not actually involve dopamine

The complex affective and cognitive capacities of rats

Posted by in category: neuroscience

For several decades, although studies of rat physiology and behavior have abounded, research on rat emotions has been limited in scope to fear, anxiety, and pain. Converging evidence for the capacity of many species to share others’ affective states has emerged, sparking interest in the empathic capacities of rats. Recent research has demonstrated that rats are a highly cooperative species and are motivated by others’ distress to prosocial actions, such as opening a door or pulling a chain to release trapped conspecifics. Studies of rat affect, cognition, and neural function provide compelling evidence that rats have some capacity to represent others’ needs, to instrumentally act to improve their well-being, and are thus capable of forms of targeted helping. Rats’ complex abilities raise the importance of integrating new measures of rat well-being into scientific research.

[Part 1] Inside the Loop: Decoding the Mystery of Self-Awareness in Cognitive Systems

Posted by in category: neuroscience

“The only journey is the one within”

Rainer Maria Rilke

Feedback loops within a system can generate seemingly contradictory or paradoxical relationships. A cognitive system might have an internal model of its mental processes, which influences its decision-making and behavior. This internal model then becomes part of the system’s overall state, creating a recursive loop where the system’s representation of itself affects its own behavior.

Bridging the Gap: How Quantum Physics Supports Metaphysical Science and Why the Scientific Community Should Embrace This Integration

Posted by in categories: neuroscience, particle physics, quantum physics, science

In the ever-evolving landscape of scientific discovery, certain paradigms periodically challenge the established norms, compelling us to reconsider the boundaries of what we deem as ‘science.’ One such paradigm is the intersection of quantum physics and metaphysical science. Despite skepticism, there is a growing body of evidence suggesting that these two fields are not only compatible but also complementary. This blog delves into how quantum physics supports metaphysical science and argues for its integration into mainstream scientific discourse, underpinned by historical precedents.

“The day science begins to study non-physical phenomena; it will make more progress in one decade than in all the previous centuries of its existence.” — Nikola Tesla

Quantum physics, the study of particles at the smallest scales of energy levels, has fundamentally altered our understanding of reality. The principles of quantum mechanics, such as superposition, entanglement, and wave-particle duality, have revealed a universe far more intricate and interconnected than classical physics ever suggested. These concepts resonate profoundly with metaphysical science, which explores the nature of reality, consciousness, and existence beyond the physical.

Quantum collapse holds the key to consciousness

Posted by in categories: neuroscience, quantum physics

Consciousness is famously unobservable. Therefore, to test for consciousness, we must study its absence rather than its presence. Stuart Hameroff here argues that by studying anesthesia we are able to understand what goes away in the brain when the light of consciousness is switched off. Hameroff finds the answer in quantum processes in the brain – recent studies suggest he is onto something.

This article is presented in association with Closer To Truth, a partner for HowTheLightGetsIn Festival 2024. The festival will feature the debate ‘The Consciousness Test’, featuring Sabine Hossenfelder, Yoshua Bengio, Nick Lane and Hilary Lawson.

Research cracks the Autism Code, making the Neurodivergent Brain Visible

Posted by in categories: biotech/medical, genetics, mathematics, neuroscience

Model grounded in biology reveals the tissue structures linked to the disorder. A researcher’s mathematical modeling approach for brain imaging analysis reveals links between genes, brain structure and autism.

A multi-university research team co-led by University of Virginia engineering professor Gustavo K. Rohde has developed a system that can spot genetic markers of autism in brain images with 89 to 95% accuracy.

Their findings suggest doctors may one day see, classify and treat autism and related neurological conditions with this method, without having to rely on, or wait for, behavioral cues. And that means this truly personalized medicine could result in earlier interventions.

New brain organoid model replicates human cortical domains

Posted by in categories: biotech/medical, neuroscience

The group of Jürgen Knoblich at the Institute of Molecular Biotechnology (IMBA) of the Austrian Academy of Sciences, has developed a new method that allows scientists to cultivate brain organoids with distinct cortical areas and front-to-back patterning.

Together with collaborators at the Human Technopole and the University of Milan-Bicocca, they report a method that gives scientists a deeper look into human-specific brain development and disorders. The study was published in Nature Methods on September 18.

Brain organoids are extensively used to study development. Derived from , the 3D models allow scientists to study unique properties of the human brain. Researchers use cortical organoids to answer fundamental questions such as how the human brain can grow to its large size or how the human brain’s long-range connections form.
