Charting sex divergence in the human brain across the lifespan

This paper constructs sex-specific lifespan brain charts using neuroimaging data from 59,915 individuals, revealing dynamic sex differences in brain development and improving detection of neuropsychiatric abnormalities.

Two fundamental timescales organize human vocal behavior

This paper identifies two distinct temporal timescales organizing human vocal behavior, showing they are present from infancy and support different functions in vocal production and synchronization.

Causal evidence for a shared mechanism linking language and tool use via the putamen

The paper identifies the putamen as a neural substrate supporting goal-dependent sequence integrity for both language and tool use, showing early language experience strengthens this mechanism.

The neural organization of visual information in the auditory cortex of the congenitally deaf

This study uses fMRI to investigate retinotopic responses in the auditory cortex of congenitally deaf individuals, finding cross-modal visual representations in the deaf but not in hearing participants.

Inner visual experience biases object neural representational geometry during perceptual encoding

The paper compares neural representational geometry during perception and imagery in visualizers and individuals with congenital aphantasia, finding differences in visual-similarity-aligned geometry during perceptual encoding.

Population-specific brain charts reveal Chinese-Western differences in neurodevelopmental trajectories

The paper develops population-specific brain charts for Chinese individuals, revealing distinct neurodevelopmental patterns compared to Western populations and showing better performance in predicting brain phenotypes.

Semantics across the globe: A universal neurocognitive semantic structure adaptive to climate

The paper identifies a universal neurocognitive semantic structure across languages, showing that semantic variations are primarily influenced by climate rather than sociocultural factors.

Unraveling the impact of congenital deafness on individual brain organization

This study investigates individual differences in brain reorganization due to congenital deafness, finding greater functional connectivity variability in deaf individuals compared to hearing individuals, influenced by language experience.

Emergent modularity in large language models: Insights from aphasia simulations

This study simulates aphasia in large language models by disrupting components to explore modularity in language processing and its parallels with human systems.

Cortical connectivity supports motoric synchronization to both auditory and visual rhythms in a frontal-temporal network

The paper identifies a common frontal-temporal network for motor synchronization to auditory and visual rhythms, showing it is based on intrinsic cortical connections rather than sensory experience.

Neural correlates of an illusionary sense of agency caused by virtual reality

This study uses virtual reality to investigate the neural correlates of an illusionary sense of agency during passive observation, finding increased temporal binding linked to the right angular gyrus and inferior parietal lobule.

Early-life language deprivation affects specific neural mechanisms of semantic representations

The paper investigates how early-life language deprivation affects neural mechanisms of semantic representations using fMRI in early deaf adults compared to sign language-acquiring controls.

Brain intrinsic connection patterns underlying tool processing in human adults are present in neonates and not in macaques

The paper compares brain networks in human adults, neonates, and macaques to show that tool processing networks exist in humans before experience but not in macaques.

The role of visual experience in brain inter-individual variability

This study shows that congenital blindness leads to more variable resting-state functional connectivity in visual cortex compared to sighted individuals, highlighting the impact of sensory experience on brain organization.

The way of the light: how visual information reaches the auditory cortex in congenitally deaf adults

This study investigates how visual information reaches the auditory cortex in congenitally deaf adults using computational models and neuroimaging techniques.

Preference for animate domain sounds in the fusiform gyrus of blind individuals is modulated by shape-action mapping

The paper shows that blind individuals' fusiform gyrus responds to human facial expression sounds, linking shape and action, but not to speech or animal sounds.

Idiosyncratic Tower of Babel: Individual differences in word meaning representation increase along abstractness

The paper investigates individual differences in word meaning representation, finding that disagreement increases with word abstractness using behavioral and neuroimaging data.

Humanoid robots are perceived as an evolutionary threat

The paper investigates how humans perceive humanoid robots as evolutionary threats, finding amygdala activation and monocular advantage similar to responses to snakes.

Computational mechanisms for neural representation of words

The paper compares word computation mechanisms using fMRI data to determine which models best explain neural activity patterns related to language processing.

Spoken language comprehension activates the primary visual cortex

Sighted participants show left-lateralized, focal V1 activation for comprehensible speech versus reversed speech, independent of word concreteness or attention to word onsets.

Visual featural topography in the human ventral visual pathway

The paper maps visual features in the human ventral visual pathway using fMRI and computational models, linking feature combinations to response-action systems.

Two Forms of Knowledge Representations in the Human Brain

The paper investigates how color knowledge is represented in the brain, finding that both sensory-derived and cognitively-derived systems exist, with a specific region supporting color knowledge in both blind and sighted individuals.

How do blind people represent rainbows? Disentangling components of conceptual representations.

The paper investigates how blind individuals represent abstract concepts like 'rainbow' and 'freedom' by analyzing brain activation patterns in different regions of the anterior temporal lobe.
