“…The MFG, a location where the ventral and dorsal attention networks converge, is involved in language fluency, object naming and directed attention and is part of the cognitive executive network ( Japee et al, 2015 ; Viñas-Guasch and Wu, 2017 ). The MTG has been proven to be an important structure in the memory consolidation process and a crucial node in the language network, as it participates in semantic control and social cognition ( Acheson and Hagoort, 2013 ; Chen Y. et al, 2020 ). As one piece of evidence, we showed exaggerated connection weights from the left dAI to the bilateral SFG, right MFG and left PreCG and from the right dAI to the right MTG and left PreCG.…”

The insular cortex is a cortical regulatory area involved in dyspnea, cognition, emotion, and sensorimotor function. Previous studies reported that obstructive sleep apnea (OSA) shows insular tissue damage and abnormal functional connections for the whole insula. The insula can be divided into different subregions with distinct functional profiles, including the ventral anterior insula (vAI) participating in affective processing, dorsal anterior insula (dAI) involved in cognitive processing, and posterior insula (PI) involved in the processing of sensorimotor information. However, the functional connectivity (FC) of these insular subregions in OSA has yet to be established. Hence, the purpose of this study was to explore the resting-state FC of the insular subregions with other brain areas and its relationship with clinical symptoms of OSA. Resting-state functional magnetic resonance imaging data from 83 male OSA patients and 84 healthy controls were analyzed by whole-brain voxel-based FC using spherical seeds from six insular subregions, namely, the bilateral vAI, dAI, and PI, to identify abnormalities in the insular subregions network and related brain regions. Ultimately, the Pearson correlation analysis was carried out between the dysfunction results and the neuropsychological tests. Compared with the healthy control group, the OSA patients exhibited disturbed FC from the dAI to areas relevant to cognition, such as the bilateral cerebellum posterior lobe, superior frontal gyrus, right middle frontal gyrus and middle temporal gyrus; decreased FC from the vAI to areas linked with emotion, such as the bilateral fusiform gyrus, superior parietal lobule, precuneus and cerebellum posterior lobe; and abnormal FC from the PI to the brain regions involved in sensorimotor such as the bilateral precentral gyrus, right superior/middle temporal gyrus and left superior frontal gyrus. The linear regression result showed that the apnea-hypopnea index was positively correlated with the increased FC between the right PI and the right precuneus (after Bonferroni correlation, P < 0.001) In conclusion, the abnormal FC between insular subregions and other brain regions were related to cognitive, emotional and sensorimotor networks in OSA patients. These results may provide a new imaging perspective for further understanding of OSA-related cognitive and affective disorders.

Semantic knowledge includes understanding of objects and their features and also understanding of the characteristics of events. The hub-and-spoke theory holds that these conceptual representations rely on multiple information sources that are integrated in a central hub in the ventral anterior temporal lobes. The dual-hub theory expands this framework with the claim that the ventral anterior temporal lobe hub is specialized for object representation, while a second hub in angular gyrus is specialized for event representation. To test these ideas, we used representational similarity analysis, univariate and psychophysiological interaction analyses of fMRI data collected while participants processed object and event concepts (e.g. “an apple,” “a wedding”) presented as images and written words. Representational similarity analysis showed that angular gyrus encoded event concept similarity more than object similarity, although the left angular gyrus also encoded object similarity. Bilateral ventral anterior temporal lobes encoded both object and event concept structure, and left ventral anterior temporal lobe exhibited stronger coding for events. Psychophysiological interaction analysis revealed greater connectivity between left ventral anterior temporal lobe and right pMTG, and between right angular gyrus and bilateral ITG and middle occipital gyrus, for event concepts compared to object concepts. These findings support the specialization of angular gyrus for event semantics, though with some involvement in object coding, but do not support ventral anterior temporal lobe specialization for object concepts.

“…PPI analysis indicated that left vATL had stronger connectivity with right pMTG when processing event concepts (Figure 6A). Right pMTG has been implicated in coding causal relations between objects (Leshinskaya & Thompson-Schill, 2020), and in representing action concepts present in videos, still images and in language (Chen et al, 2020; Watson et al, 2013). The increased connectivity between vATL and pMTG may be a result of an enhanced contribution of relational and action-related information when understanding event concepts.…”

Semantic knowledge includes understanding of objects and their features and also understanding of the characteristics of events. The hub-and-spoke theory holds that these conceptual representations rely on multiple information sources that are integrated in a central hub in the ventral anterior temporal lobes (vATL). Dual-hub theory expands this framework with the claim that the vATL hub is specialized for object representation, while a second hub in angular gyrus (AG) is specialized for event representation. To test these ideas, we used RSA, univariate and PPI analyses of fMRI data collected while participants processed object and event concepts (e.g., an apple, a wedding) presented as images and written words. RSA showed that AG encoded event concept similarity more than object similarity, although the left AG also encoded object similarity. Bilateral vATLs encoded both object and event concept structure, and left vATL exhibited stronger coding for events. PPI analysis revealed greater connectivity between left vATL and right pMTG, and between right AG and bilateral ITG and middle occipital gyrus, for event concepts compared to object concepts. These findings support the specialization of AG for event semantics, though with some involvement in object coding, but do not support vATL specialization for object concepts.
