Linking fast and slow
“Linking fast and slow: The case for generative models” A pervasive challenge in neuroscience is testing whether neuronal connectivity changes over time due to specific causes, such as stimuli, events, or clinical interventions. Recent hardware innovations and falling data storage costs enable longer, more naturalistic neuronal recordings. The implicit opportunity for understanding the self-organised brain…

Exploration and Exploitation & Coping Strategy
“Transition Dynamics Between Exploration and Exploitation Predicts Individual Differences in Coping Strategy” Adaptive decision-making requires balancing exploitation of known rewarding options with exploration of uncertain alternatives, a dilemma also known as the exploration-exploitation tradeoff. While this framework has been widely studied in reinforcement learning research, its relevance to coping, defined as the cognitive and behavioral…

Your brain on nature
“Your brain on nature: A scoping review of the neuroscience of nature exposure” The relationship between natural environments and human cognition has gathered increasing attention across disciplines, including neuroscience, environmental psychology, and public health. An expanding body of empirical evidence supports the notion that exposure to nature consistently promotes psychological and physiological well-being. However, our…

Switching, fast and slow
“Switching, fast and slow: Deciphering the dynamics of memory search, its brain connectivity patterns, and its role in creativity “ Creative ideas emerge from the process of searching and combining concepts in memory, involving both associative and controlled mechanisms. How these processes unfold during memory search and relate to creativity remains unclear. We explored the neurocognitive…

Paradox of Predictability
“The paradox of predictability provides a bridge between micro- and macroevolution” The relationship between the evolutionary dynamics observed in contemporary populations (microevolution) and evolution on timescales of millions of years (macroevolution) has been a topic of considerable debate. Historically, this debate centers on inconsistencies between microevolutionary processes and macroevolutionary patterns. Here, we characterize a striking…

Explore 2025 with Leif Penguinson
“Explore 2025 with Leif Penguinson” Around the world in 48 penguin puzzles! Can you spot the penguin in every game this year? For five years now, Briefing readers have eagerly awaited Fridays for a chance to put their penguin-hunting skills to the test. Each week, Leif Penguinson, a Rockhopper penguin, travels to scientifically interesting (and…

The Universe Learning Itself
“The Universe Learning Itself: On the Evolution of Dynamics from theBig Bang to Machine Intelligence” We develop a unified, dynamical-systems narrative of the universe that traces a continuous chain of structure formation from the Big Bang to contemporary human societies and their artificial learning systems. Rather than treating cosmology, astrophysics, geophysics, biology, cognition, and machine…

Decoding the architecture of living systems
“Decoding the architecture of living systems“, by Manlio De Domenico The possibility that evolutionary forces — together with a few fundamental factors such as thermodynamic constraints, specific computational features enabling information processing, and ecological processes — might constrain the logic of living systems is tantalizing. However, it is often overlooked that any practical implementation of…

Mapping interactions between adversity and neuroplasticity across development
“Mapping interactions between adversity and neuroplasticity across development” Highlights: The human brain undergoes a protracted course of development that provides prolonged opportunities to be sculpted by experience. Yet, persistent definitional and measurement challenges have complicated efforts to understand how experience interacts with neuroplasticity during human development. Here, we synthesize previously siloed perspectives to propose an…

Statistics is not measurement
“Statistics is not measurement: The inbuilt semantics of psychometric scales and language-based models obscures crucial epistemic differences” This article provides a comprehensive critique of psychology’s overreliance on statistical modelling at the expense of epistemologically grounded measurement processes. It highlights that statistics deals with structural relations in data regardless of what these data represent, whereas measurement…

Why collective behavioursself-organize to criticality
“Why collective behaviours self-organize to criticality: a primer on information-theoretic and thermodynamic utility measures” Collective behaviours are frequently observed to self‑organize to criticality. Existing proposals to explain these phenomena are fragmented across disciplines and only partially answer the question. This primer compares the underlying, intrinsic, utilities that may explain the self‑organization of collective behaviours near…

Stubborn Goals: the adaptive value
“The adaptive value of stubborn goals” Humans exhibit a striking tendency to persist with chosen goals. This strong attachment to goals can often appear irrational – a perspective captured by terms such as perseverance or sunk-cost biases. In this review, we explore how goal commitment could stem from several adaptive mechanisms, including those that optimise…

Blocking of associative learning by explicit descriptions
“Blocking of associative learning by explicit descriptions” People given written descriptions often learn and decide differently from those learning from experience, even in formally identical tasks. This paper presents two experiments detailing how telling participants about the value of one stimulus impacts a keystone learning effect – blocking. The paper investigates if descriptions can be…

Fast, slow, & metacognitive
“Fast, slow, and metacognitive thinking in AI” Inspired by the ”thinking fast and slow” cognitive theory of human decision making, we propose a multi-agent cognitive architecture (SOFAI) that is based on ”fast”/”slow” solvers and a metacognitive module. We then present experimental results on the behavior of an instance of this architecture for AI systems that…

Computational Framework for cognitive biology
“Toward a computational framework for cognitive biology: Unifying approaches from cognitive neuroscience and comparative cognition” Progress in understanding cognition requires a quantitative, theoretical framework, grounded in the other natural sciences and able to bridge between implementational, algorithmic and computational levels of explanation. This review article reviews recent results in neuroscience and cognitive biology that, when combined, provide key components…

Brain-body physiology
“Brain-body physiology: Local, reflex, and central communication” Behavior is tightly synchronized with bodily physiology. Internal needs from the body drive behavior selection, while optimal behavior performance requires a coordinated physiological response. Internal state is dynamically represented by the nervous system to influence mood and emotion, and body-brain signals also direct responses to external sensory cues,…

Divergent Perception: Framing Creative Cognition
“Divergent Perception: Framing Creative Cognition Through the Lens of Sensory Flexibility” “Savoir regarder est un moyen d’inventer.” Salvador Dali. Creativity is a cornerstone of human evolution and is typically defined as the multifaceted ability to produce novel and useful artifacts. Although much research has focused on divergent thinking, growing evidence underscores the importance of perceptual…
