Feature similarity, a sensitive method to capture the functional interaction of brain regions and networks to support flexible behavior Open
The brain is a dynamic system where complex behaviours emerge from interactions across distributed regions. Accurately linking brain function to cognition requires methods sensitive to these interactions. We introduce Feature Similarity (F…

Frequency-specific maturation of cortical organization and social-cognitive links from childhood to adolescence Open
The human brain unfolds its functional architecture over multiple timescales during childhood and adolescence, yet we know little about how these developmental trajectories vary between individuals. Slow brain signals at different frequenc…

Patterns of ongoing thought in the real world and their links to mental health and well-being Open
The thoughts we experience in daily life have implications for our mental health and well-being. However, it is often difficult to measure thought patterns outside of laboratory conditions due to concerns about the voracity of measurements…

Hippocampal mismatch signals are based on episodic memories and not schematic knowledge Open
Prediction errors drive learning by signaling mismatches between expectations and reality, but the neural systems supporting these computations remain debated. The hippocampus is implicated in mismatch detection, yet it is not known whethe…

The Semantic Underpinnings of Speech Disorganization in Schizophrenia Open
Effective communication relies on shared semantic representations and their context-sensitive retrieval. Accordingly, difficulties in communicating coherently, as seen in some patients with schizophrenia, may reflect impairments at the lev…

Feature similarity: a sensitive method to capture the functional interaction of brain regions and networks to support flexible behavior Open
The brain is a dynamic system where complex behaviours emerge from interactions across regions. Linking brain function to cognition requires tools that are sensitive to these dynamics. We introduce a technique, Feature Similarity (FS), whi…

Domain-General Brain Networks Support Language Development Open
Understanding the neural basis of verbal intelligence across development requires disentangling the contributions of domain-general and language-selective brain systems. Although language is often considered a domain-specific function, com…

The spatial layout of antagonistic brain regions is explicable based on geometric principles Open
Brain activity emerges in a dynamic landscape of regional increases and decreases that span the cortex. Increases in activity during a cognitive task are often assumed to reflect the processing of task-relevant information, while reduction…

Whole-Brain Dimensions of Intrinsic Connectivity Capture Modality-Specific and Heteromodal Language Representations Open
Comprehension of spoken and written language involves a hierarchical sequence of modality-specific and heteromodal processes. While these have been localized to different regions, modality-selective responses extend beyond them, implicatin…

Mapping cognition across lab and daily life using Experience-Sampling Open
The goal of psychological research is to understand behaviour in daily life. Although lab studies provide the control necessary to identify cognitive mechanisms behind behaviour, how these controlled situations generalise to activities in …

The intrinsic cortical geometry of reading Open
Reading involves dual streams of sensory propagation that lie within a broader sensory-to-transmodal hierarchy. This study explores whether individual differences in this functional organization can be explained by cortical geometry. Throu…

Hippocampus responds to mismatches with predictions based on episodic memories but not generalised knowledge Open
Prediction errors drive learning by signalling a mismatch between our expectations and reality. The hippocampus plays a key role in mismatch detection, but it is not known what information the hippocampus uses to form expectations. Here we…
View article: A double dissociation between semantic and spatial cognition in visual to default network pathways
A double dissociation between semantic and spatial cognition in visual to default network pathways Open
Processing pathways between sensory and default mode network (DMN) regions support recognition, navigation, and memory but their organisation is not well understood. We show that functional subdivisions of visual cortex and DMN sit at oppo…

Divergent and convergent creativity relate to different aspects of semantic control Open
Past work has demonstrated a link between semantic memory and verbal creativity. Yet, few studies have considered this relationship through the lens of the controlled semantic cognition account, which anticipates that multimodal concepts i…

The Dimensionality of Neural Coding for Cognitive Control Is Gradually Transformed within the Lateral Prefrontal Cortex Open
Cognitive control relies on neural representations that are inherently high-dimensional and distributed across multiple subregions in the prefrontal cortex (PFC). Traditional approaches tackle prefrontal representation by reducing it into …

Naming speed during language production in younger and older adults: Examining the effects of sentence context Open
Word retrieval during speech production has been found to slow down with ageing. Usually, words are produced in sentence contexts. The current studies examined how different sentence contexts influence lexical retrieval in younger and olde…

Mapping patterns of thought onto brain activity during movie-watching Open
Movie-watching is a central aspect of our lives and an important paradigm for understanding the brain mechanisms behind cognition as it occurs in daily life. Contemporary views of ongoing thought argue that the ability to make sense of eve…

Diverse Frontoparietal Connectivity Supports Semantic Prediction and Integration in Sentence Comprehension Open
Predictive processing in the parietal, temporal, frontal, and sensory cortex allows us to anticipate future meanings to maximize the efficiency of language comprehension, with the temporoparietal junction (TPJ) and inferior frontal gyrus (…
