  • white matter structural connectivity underlying Semantic Processing evidence from brain damaged patients
    Brain, 2013
    Co-Authors: Gaolang Gong, Yong He, Alfonso Caramazza, Yanchao Bi
    Abstract:

    Widely distributed brain regions in temporal, parietal and frontal cortex have been found to be involved in Semantic Processing, but the anatomical connections supporting the Semantic system are not well understood. In a group of 76 right-handed brain-damaged patients, we tested the relationship between the integrity of major white matter tracts and the presence of Semantic deficits. The integrity of white matter tracts was measured by percentage of lesion voxels obtained in structural imaging and mean fractional anisotropy values obtained in diffusion tensor imaging. Semantic deficits were assessed by jointly considering the performance on three Semantic tasks that vary in the modalities of input (visual and auditory stimuli) and output (oral naming and associative judgement). We found that the lesion volume and fractional anisotropy value of the left inferior fronto-occipital fasciculus, left anterior thalamic radiation, and left uncinate fasciculus significantly correlated with severity of impairment in all three Semantic tasks. These associations remained significant even when we controlled for a wide range of potential confounding variables, including overall cognitive state, whole lesion volume, or type of brain damage. The effects of these three white matter tracts could not be explained by potential involvement of relevant grey matter, and were (relatively) specific to object Semantic Processing, as no correlation with performance on non-object Semantic control tasks (oral repetition and number Processing tasks) was observed. These results underscore the causal role of left inferior fronto-occipital fasciculus, left anterior thalamic radiation, and left uncinate fasciculus in Semantic Processing, providing direct evidence for (part of) the anatomical skeleton of the Semantic network. * Abbreviations : ATR : anterior thalamic radiation IFOF : inferior fronto-occipital fasciculus MMSE : Mini-Mental State Examination UF : uncinate fasciculus

  • A Tri-network Model of Human Semantic Processing.
    Frontiers in Psychology, 2017
    Co-Authors: Yangwen Xu, Yong He, Yanchao Bi
    Abstract:

    Humans process the meaning of the world via both verbal and nonverbal modalities. It has been established that widely distributed cortical regions are involved in Semantic Processing, yet the global wiring pattern of this brain system has not been considered in the current neurocognitive Semantic models. We review evidence from the brain-network perspective, which shows that the Semantic system is topologically segregated into three brain modules. Revisiting previous region-based evidence in light of these new network findings, we postulate that these three modules support multimodal experiential representation, language-supported representation, and Semantic control. A tri-network neurocognitive model of Semantic Processing is proposed, which generates new hypotheses regarding the network basis of different types of Semantic processes.

  • The Effect of Sweet Taste on Romantic Semantic Processing: An ERP Study.
    Frontiers in Psychology, 2019
    Co-Authors: Liusheng Wang, Qian Chen, Yan Chen, Ruitao Zhong
    Abstract:

    Previous studies have found that sweet perception affects the subjective evaluation of interpersonal intimacy and romantic Semantic Processing. However, the cognitive processes involved in this effect are unclear. The aim of the current study was to investigate the sweet-love embodied effect in Semantic Processing and its underlying mechanism by Event-Related potentials technique. Participants were randomly exposed to sweet-taste or tasteless conditions, during which they performed a lexical decision-task that involved romantic and non-romantic words. The results showed an enhanced N400 for romantic words compared to non-romantic words in the sweet-taste condition, and a larger P200 for romantic words relative to non-romantic words. The results demonstrate that taste sensations can cross-modally facilitate the Semantic Processing of romanticness. These findings support the embodied effect of sweet-love and are discussed from the perspective of embodied cognition with knowledge activation of concept and Semantic richness.

  • Experiencing Sweet Taste Affects Romantic Semantic Processing
    Current Psychology, 2018
    Co-Authors: Liusheng Wang, Qian Chen
    Abstract:

    Studies have found that the perception of sweet taste can affect attitudes towards others, and promote the evaluation of intimate relationships. However, the effect of sweetness perception on romantic Semantic Processing remains unclear. The current study was to investigate whether the experiencing of sweet taste affects the Processing of romantic words. Participants were randomly assigned to sweet taste and tasteless conditions, in which they performed a lexical decision task. The results showed the romantic advantage effect that participants in sweet taste condition processed romantic words more rapidly than Processing non-romantic words. No gender difference was found on size of romantic advantage effect in sweet taste condition. These results support the embodied cognition hypothesis of romantic Semantic Processing.
