words constitute nearly half of the human lexicon and are critically associated with abstract thoughts, yet little is known about how they represented in brain. We tested neural basis 2 classical cognitive notions meaning representation: by linguistic contexts semantic features. collected fMRI BOLD responses for 360 built theoretical representational models from state-of-the-art corpus-based natural language processing behavioral ratings Representational similarity analyses revealed that...
Concepts can be related in many ways. They belong to the same taxonomic category (e.g., "doctor" and "teacher," both of people) or associated with event context "stethoscope," medical scenarios). How are these two major types semantic relations coded brain? We constructed stimuli from three categories (people, manmade objects, locations) thematic (school, medicine, sports) investigated neural representations dimensions using representational similarity analyses human participants (10 men...
Neuroimaging studies have consistently indicated that semantic processing involves a brain network consisting of multimodal cortical regions distributed in the frontal, parietal, and temporal lobes. However, little is known about how information organized processed within network. Some recent sensory–motor modulates activation this Other responds more to social than other information. Using fMRI, we collectively investigated activations evoked by manipulating sociality imageability verbs...
Modern linguistic theories and network science propose that language speech processing are organized into hierarchical, segregated large-scale subnetworks, with a core of dorsal (phonological) stream ventral (semantic) stream. The two streams asymmetrically recruited in receptive expressive or tasks, which showed flexible functional segregation integration. We hypothesized the was supported by underlying segregation. A dynamic conditional correlation approach employed to construct framewise...
Access to semantic information of visual word forms is a key component reading comprehension. In this study, we examined the involvement form area (VWFA) in process by investigating whether and how activity patterns VWFA are influenced during tasks. We asked participants perform two tasks - taxonomic or thematic categorization on words while obtaining blood-oxygen-level-dependent (BOLD) fMRI responses each word. Representational similarity analysis with four types relations (taxonomic,...
Brain network dynamics not only endow the brain with flexible coordination for various cognitive processes but also a huge potential of neuroplasticity development, skill learning, and after cerebral injury. Diffusive progressive glioma infiltration triggers functional compensation, which is an outstanding pathophysiological model investigation reorganization underlying neuroplasticity. In this study, we employed dynamic conditional correlation to construct framewise language networks...
We can sense an object’s shape by vision or touch. Previous studies suggested that the inferolateral occipitotemporal cortex (ILOTC) implements supramodal representations as it responds more to seeing touching objects than shapeless textures. However, such activation in anterior portion of ventral visual pathway could be due conceptual representation object imagery triggered object. addressed these possibilities directly comparing and early blind (who lack experience/imagery) sighted...
Abstract The representation of object categories is a classical question in cognitive neuroscience and compelling evidence has identified specific brain regions showing preferential activation to evolutionary significance. However, the potential contributions category processing by tuning connectivity patterns are largely unknown. Adopting continuous multicategory paradigm, we obtained whole‐brain functional (FC) each four (faces, scenes, animals tools) healthy human adults applied...
Grid-cells firing fields tile the environment with a 6-fold periodicity during both locomotion and visual exploration. Here, we tested, in humans, whether movements of covert attention elicit grid-like coding using frequency tagging. Participants observed trajectories presented sequentially at fixed rate, allowing different spatial periodicities (e.g., 4-, 6-, 8-fold) to have corresponding temporal 1, 1.5, 2 Hz), thus resulting distinct spectral responses. We found higher response for...
The human ventral visual cortex is functionally organized into different domains that sensitively respond to categories, such as words and objects. There heated debate over what principle constrains the locations of those domains. Taking word form area (VWFA) an example, we tested whether preference in this originates from bottom-up processes related shape (the hypothesis) or top-down connectivity higher-order language regions hypothesis). We trained subjects associate identical,...
Abstract Cognitive maps in the hippocampal-entorhinal system are central for representation of both spatial and non-spatial relationships. Although this system, especially humans, heavily relies on vision, role visual experience shaping development cognitive remains largely unknown. Here, we test sighted early blind individuals imagined navigation fMRI real-world navigation. During navigation, Human Navigation Network, constituted by frontal, medial temporal, parietal cortices, is reliably...
Our brain constructs reality through narrative and argumentative thought. Some hypotheses argue that these two modes of cognitive functioning are irreducible, reflecting distinct mental operations underlain by separate neural bases; Others ascribe both to a unitary system dedicated long-timescale information. We addressed this question employing inter-subject measures investigate the stimulus-induced responses when participants were listening texts during fMRI. found following kinds enhanced...
Abstract Language and social cognition are traditionally studied as separate cognitive domains, yet accumulative studies reveal overlapping neural correlates at the left ventral temporoparietal junction (vTPJ) lateral anterior temporal lobe (lATL), which have been attributed to sentence processing concept activation. We propose a common component underlying both effects -- social-semantic working memory. confirmed two key predictions of our hypothesis using fMRI: First, vTPJ lATL showed...
Abstract Spatial navigation in humans relies heavily on vision. However, the impact of early blindness brain network and hippocampal-entorhinal system supporting cognitive maps, particular, remains elusive. Here, we tested sighted blind individuals both imagined fMRI real-world navigation. During navigation, Human Navigation Network was reliably activated groups, showing resilience to visual deprivation. neural geometry analyses highlighted crucial differences between groups. A 60°...
Summary The neural system that encodes heading direction in humans is found consistently the medial and superior parietal cortex entorhinal-retrosplenial circuit. However, it still unclear whether these different regions represented within an allocentric or egocentric coordinate system. To investigate this problem, we first asked encoding (putatively) facing also encode (unambiguously) goal direction. Second, assessed directional coding scaled with preference for perspective during everyday...
