Mapping minds: The neural fingerprint of team flow dynamics

Leveraging a new algorithm to uncover long-term neural traits in social interaction

2025-04-18
(Press-News.org) Summary:

A collaborative study by researchers from Toyohashi University of Technology and California Institute of Technology (Caltech) introduces a groundbreaking algorithm that maps individual brain activity in a multi-dimensional space. This “neural fingerprint” reveals stable, long-term neural traits that interplay with transient brain states during social interactions. The study demonstrates that individuals whose neural fingerprints are more aligned tend to more readily enter a shared state of deep focus—commonly known as team flow—which has profound implications for enhancing teamwork and performance across various high-stakes environments.

Researchers set out to decode the neural mechanisms underpinning team flow by analyzing EEG (electroencephalogram) data collected from participants as they engaged in a rhythm-based, collaborative video game. By applying a novel algorithm, they generated a multi-dimensional map that captures each person’s unique brain signature—a fingerprint of how they perform and experience tasks. Their findings indicate that while these neural traits remain remarkably stable over time (comparable to personality traits), a subset of these traits gives rise to the moment-to-moment brain states observed during team flow.

In the experiment, participants alternated between solo and cooperative gameplay. The study showed that when participants’ brain signatures were closely matched within the 7D space, they were significantly more likely to achieve a shared state of deep concentration, even when faced with external distractions. This dynamic synergy provides new insights into how long-term neural traits guide real-time social interactions and decision-making.

The implications of these discoveries span a wide array of fields—from optimizing team performance in creative industries and corporate settings to enhancing cooperative dynamics in challenging environments like space missions. By bridging the gap between enduring neural markers and transient cognitive states, this research offers a promising avenue for developing methods to predict and foster effective collaboration.

Patients support AI as radiologist backup in screening mammography

2025-04-18
OAK BROOK, Ill. – The results of a large survey from a diverse patient population revealed cautious support for artificial intelligence (AI) implementation in screening mammography, according to a study published today in Radiology: Imaging Cancer, a journal of the Radiological Society of North America (RSNA). Personal medical history and sociodemographic factors influenced respondent’s level of trust in AI. While the diagnostic accuracy of AI systems has drastically improved in recent ...

AACR: MD Anderson’s John Weinstein elected Fellow of the AACR Academy

2025-04-18
CHICAGO ― John N. Weinstein, M.D., Ph.D., chair of Bioinformatics and Computational Biology and professor of Systems Biology at The University of Texas MD Anderson Cancer Center, has been elected to the 2025 class of Fellows of the American Association for Cancer Research (AACR) Academy in recognition of decades of combined laboratory and computational work pioneering multi-omic molecular profiling, including the introduction of new laboratory techniques, clustered heat maps, and early innovations in artificial intelligence for cancer drug discovery. The mission of the AACR Academy is to honor distinguished scientists whose contributions have propelled ...

Existing drug has potential for immune paralysis

2025-04-18
When the immune system does not function properly, individuals become more susceptible to infections caused by viruses, bacteria, or fungi. Researchers from Radboud university medical center have demonstrated that an existing drug can revive immune cells that are not functioning correctly. These findings provide leads for further research in patients admitted to the intensive care unit (ICU) with sepsis.    Twenty percent of global deaths are associated with sepsis, and it is the leading cause of death in ICUs. Sepsis is characterized by organ failure, for instance of the kidneys or lungs, caused by a dysregulated immune response to an infection. Patients with ...

Soft brainstem implant delivers high-resolution hearing

2025-04-18
Over the last couple of decades, many people have regained hearing functionality with the most successful neurotech device to date: the cochlear implant. But for those whose cochlear nerve is too damaged for a standard cochlear implant, a promising alternative is an auditory brainstem implant (ABI). Unfortunately, current ABIs are rigid implants that do not allow for good tissue contact. As a result, doctors commonly switch off a majority of the electrodes due to unwanted side effects such as dizziness or facial twitching—leading most ...

Uncovering the structural and regulatory mechanisms underlying translation arrest

2025-04-18
Proteins form the structural and functional backbone of the cell, and any perturbation in their synthesis can disrupt normal cellular functions. The DNA blueprint is carefully read, transcribed, and translated into functional proteins through a tightly regulated process. The ‘ribosome’ plays a crucial role in orchestrating the translation of the messenger RNA transcript by assembling amino acids into the corresponding polypeptide sequence. Ribosomal functions beyond protein synthesis have been uncovered over the years, revealing its role ...

Scientists develop strategy to improve flexible tandem solar cell performance

2025-04-18
Chinese scientists have found a way to make flexible tandem solar cells more efficient and durable by enhancing the adhesion of top layers to the bottom layers of the cell. Copper indium gallium selenide (CIGS) is a commercial semiconductor known for its outstanding adjustable bandgap, strong light absorption, low-temperature sensitivity, and superior operational stability, making it a promising candidate for bottom-cell use in next-generation tandem solar cells. Flexible perovskite/CIGS tandem solar cell combines a top layer of perovskite—a material that efficiently converts sunlight into electricity—with ...

Pushing boundaries: Detecting the anomalous Hall effect without magnetization in a new class of materials

2025-04-18
An international research team led by Mayukh Kumar Ray, Mingxuan Fu, and Satoru Nakatsuji from the University of Tokyo, along with Collin Broholm from Johns Hopkins University, has discovered the anomalous Hall effect in a collinear antiferromagnet. More strikingly, the anomalous Hall effect emerges from a non-Fermi liquid state, in which electrons do not interact according to conventional models. The discovery not only challenges the textbook framework for interpreting the anomalous Hall effect but also widens the range of antiferromagnets ...

Generative AI’s diagnostic capabilities comparable to non-specialist doctors

2025-04-18
The use of generative AI for diagnostics has attracted attention in the medical field and many research papers have been published on this topic. However, because the evaluation criteria were different for each study, a comprehensive analysis was needed to determine the extent AI could be used in actual medical settings and what advantages it featured in comparison to doctors. A research group led by Dr. Hirotaka Takita and Associate Professor Daiju Ueda at Osaka Metropolitan University’s Graduate School of Medicine conducted a meta-analysis of generative AI’s diagnostic capabilities using 83 research papers published between June ...

Journal in Which the Study was Published: Clinical Cancer Research, a journal of the American Association for Cancer Research (AACR) Authors: Senior author Mark Awad, MD, PhD, chief of the Thoracic Oncology Service at Memorial Sloan Kettering Cancer Center, and first author Federica Pecci, MD, a research fellow at Dana-Farber Cancer Institute Background: Immune ...

Native American names extend the earthquake history of northeastern North America

2025-04-18
In 1638, an earthquake in what is now New Hampshire had Plymouth, Massachusetts colonists stumbling from the strong shaking and water sloshing out of the pots used by Native Americans to cook a midday meal along the St. Lawrence River, according to contemporaneous reports. When Roger Williams, founder of the Rhode Island colony, talked with local Native Americans, he reported that the younger tribe members were surprised by the earthquake. But older tribe members said they had felt similar shaking four times in the past 80 years. In his talk at the Seismological ...
