Rock guitarists show increased neural activity in Brodmann area 45 of the brain when improvising

A neuroimaging study of guitarists found increased activity in the Brodmann area 45 of the brain while they were improvising blues rock sequences. This area is located in the inferior frontal gyrus area of the frontal cortex and is a part of the wider Broca’s area. The research was published in BMC Research Notes. Creativity is the ability to generate new, original, and valuable ideas or solutions. It involves complex cognitive processes, including divergent thinking, which is the ability to think about many different ideas at once and explore multiple possible solutions. Creatively gifted individuals often exhibit the capacity to make unusual connections, think outside the conventional frameworks, and challenge norms or traditional practices. One manifestation of creativity is musical improvisation. Musical improvisation is the spontaneous composition of music in real-time. While improvising, musicians perform without specific preparation or pre-composed material, creatively expressing ideas and emotions through their instruments or voices. The neural foundations of creativity are believed to be spread across multiple brain regions. Critical areas involved in creative thinking include the prefrontal cortex, …

What is an AI neural network and how do they work?

AI neural networks, inspired by the human brain are a foundational technology in the field of artificial intelligence. They are designed to recognize patterns and make decisions with a level of complexity that was previously unattainable for machines. An AI neural network is a computational model inspired by the structure and functional aspects of biological neural networks found in the human brain. What is a neural network? It consists of interconnected units or nodes called neurons, which process information by responding to external inputs and relaying information between each other. The connections between these neurons are known as synapses and are responsible for transmitting signals and facilitating learning. Below is a concise summary of key points to remember about neural networks. Key Takeaways Neural networks consist of interconnected nodes, akin to neurons, which process information in a layered structure. They are capable of learning from data through a process called training, where the network adjusts its parameters to minimize error. AI neural networks are used for a variety of tasks such as image and speech …

How Neural Concept’s aerodynamic AI is shaping Formula 1

How Neural Concept’s aerodynamic AI is shaping Formula 1

It’s a long way from pedal bikes to Formula 1. But that’s precisely the quantum leap that AI-based startup Neural Concept and its co-founder and CEO, Pierre Baqué, made in just six years. In 2018, the company’s fledgling software helped develop the world’s most aerodynamic bicycle. Today, four out of 10 Formula 1 teams use an evolution of that same technology. Along the way, Baqué’s company picked up contracts with aerospace suppliers like Airbus and Safran, earning a $9.1 million Series A raise in 2022. Now at 50 employees, Switzerland-based Neural Concept is working toward a Series B round while its software helps historic F1 teams like Williams Racing find their way back to the top of the world’s premiere form of motorsport. However, where Formula 1 cars rely on 1,000-horsepower hybrid V6 engines, Baqué’s first practical application of the technology was human-powered. Pedal power In 2018, Baqué was studying at the École Polytechnique Fédérale de Lausanne’s Computer Vision Laboratory, working on applying machine learning techniques to three-dimensional problems. “I was put in contact with …

Borderline personality disorder not linked to abnormal neural processing of facial expressions, study finds

Borderline personality disorder not linked to abnormal neural processing of facial expressions, study finds

A neuroimaging study of young people with borderline personality disorder show that brain activity of these individuals when processing facial expressions does not differ from that of healthy individuals. The only difference was lower heart rate variability compared to healthy participants. The paper was published in Borderline Personality Disorder and Emotion Dysregulation. Borderline personality disorder is a mental health condition characterized by intense emotional instability, impulsive behaviors, and unstable relationships. Individuals with borderline personality disorder experience rapid mood swings, have an intense fear of abandonment, and a distorted sense of self. They may engage in risky behaviors, have difficulty managing anger, and struggle with feelings of emptiness or loneliness. People with this disorder may also experience dissociation, a feeling of detachment from themselves or reality, particularly when they are under stress. One of the hallmark features of borderline personality disorder is the dysregulation of emotions. Human faces are potent emotional stimuli, and researchers frequently use images of faces to study emotion processing. Results from these studies suggest that individuals with borderline personality disorder often struggle …

‘Neural noise’ could be a hidden advantage of the autistic mind

‘Neural noise’ could be a hidden advantage of the autistic mind

Autism is a neurodevelopmental difference associated with specific experiences and characteristics. For decades, autism research has focused on behavioural, cognitive, social and communication difficulties. These studies highlighted how autistic people face issues with everyday tasks that allistic (meaning non-autistic) people do not. Some difficulties may include recognising emotions or social cues. But some research, including our own study, has explored specific advantages in autism. Studies have shown that in some cognitive tasks, autistic people perform better than allistic people. Autistic people may have greater success in identifying a simple shape embedded within a more complex design, arranging blocks of different shapes and colours, or spotting an object within a cluttered visual environment (similar to Where’s Wally?). Such enhanced performance has been recorded in babies as young as nine months who show emerging signs of autism. How and why do autistic individuals do so well on these tasks? The answer may be surprising: more “neural noise”. What is neural noise? Generally, when you think of noise, you probably think of auditory noise, the ups and downs …

Microdoses of LSD enhance neural complexity, study finds

Microdoses of LSD enhance neural complexity, study finds

A recent study has shown that even very low doses of LSD can enhance the complexity of brain activity, a finding that might have significant implications for our understanding of consciousness and possibly for therapeutic applications. The study, published in the journal Neuropsychopharmacology, found that while substances like THC (tetrahydrocannabinol) and methamphetamine did not produce the same effect, LSD distinctly increased neural complexity and affected brain wave patterns associated with states of consciousness. Neural complexity is a concept that attempts to quantify the intricate patterns of activity within the brain. This measure reflects the “richness” of one’s mental experience, which can vary dramatically from one state of consciousness to another. High levels of neural complexity are associated with a richer, more varied experience of consciousness, whereas lower levels are associated with reduced consciousness, such as in sleep or under the influence of certain sedatives. The focus on neural complexity in this study stems from a theory known as the “entropic brain hypothesis,” which proposes that the therapeutic benefits of psychedelics are partly due to their …

Scientists identify potential neural pathway to treat alcohol dependency in trauma survivors

Scientists identify potential neural pathway to treat alcohol dependency in trauma survivors

In a recent study, neuroscientists from Scripps Research discovered that targeting specific neurons involved in the brain’s stress response could potentially reduce alcohol consumption in individuals suffering from both post-traumatic stress disorder (PTSD) and alcohol use disorder (AUD). Published in Molecular Psychiatry, this research offers a promising direction for developing new treatment strategies for people grappling with these interlinked disorders. Individuals with PTSD are at a heightened risk of developing AUD, often using alcohol as a coping mechanism to mitigate the symptoms of PTSD, such as anxiety, depression, and the distress from traumatic memories. This self-medication hypothesis suggests that alcohol may temporarily reduce the emotional pain and stress associated with PTSD, albeit with long-term negative consequences. Existing pharmacotherapies to simultaneously address PTSD and AUD are scarce and often inadequate. The overlapping symptoms and mutual reinforcement of PTSD and AUD complicate treatment approaches, highlighting an urgent need for novel therapeutic strategies that can target both conditions effectively. “Traumatic experiences in life can increase vulnerability to alcohol drinking and exacerbate symptoms of depression and anxiety,” explained senior …

Wine expertise reshapes the brain: Sommeliers show altered neural activity when tasting wine

Wine expertise reshapes the brain: Sommeliers show altered neural activity when tasting wine

Sommeliers harness their extensive training to discern and describe the nuanced features of wines. A new study published in Human Brain Mapping explores the minds of these experts, revealing that sommeliers not only exhibit structural differences in their brains compared to casual wine drinkers but also showcase unique patterns of brain activity and connectivity when evaluating wines. This research underscores how specialized training in wine tasting doesn’t just refine the palate — it reshapes the brain itself, enhancing the integration of taste, smell, and the linguistic prowess needed to articulate the complex sensory experiences of wine. The study was spearheaded by Manuel Carreiras, the scientific director of the Basque Center on Cognition, Brain and Language. At the heart of the inquiry was a curiosity about how extensive training and experience — such as that of sommeliers in wine tasting — manifest in the brain. Previous research has shown that expertise in various domains, like music, language, and sports, can lead to both functional and structural brain changes. The researchers aimed to determine whether similar neural …
