“…The first group of structures includes the lateral orbitofrontal cortex, the insular cortex, and rostral middle frontal gyrus, which were reported to be related to emotion regulation (Gross, 2002;Hooker and Knight, 2010), disgust processing (Calder et al, 2000;Krolak-Salmon et al, 2003;Wright et al, 2004), and emotion generation (Waugh et al, 2010(Waugh et al, , 2014Roy et al, 2012), respectively. Next, two word recognition related structures, left inferior temporal lobe (Sharp et al, 2004;Antonucci et al, 2008;Trimmel et al, 2018) and lingual gyrus (Mechelh et al, 2000;Xiao et al, 2005;Ghosh et al, 2010), were activated more for congruent trials than for incongruent ones, and the same pattern applies to parahippocampal gyrus, a structure involved in emotion identification and regulation (Almeida et al, 2009;Zhu et al, 2019). In the third ROI, the rostral anterior cingulate cortex is the neural locus for sad information processing as suggested recently (Niida and Mimura, 2017;Ramirez-Mahaluf et al, 2018;Webb et al, 2018).…”

Introduction:The present study investigated how new words with acquired connotations of disgust and sadness, both negatively valenced but distinctive emotions, modulate the brain dynamics in the context of emotional sentences.Methods:Participants completed a learning session in which pseudowords were repeatedly paired with faces expressing disgust and sadness. An event-related potential (ERP) session followed the next day, in which participants received the learned pseudowords (herein, new words) combined with sentences and were asked to make emotional congruency judgment.Results:Sad new words elicited larger negative waveform than disgusting new words in the 146–228 ms time window, and emotionally congruent trials showed larger positive waveform than emotionally incongruent trials in the 304–462 ms time window. Moreover, the source localization in the latter suggested that congruent trials elicited larger current densities than incongruent trials in a number of emotion-related brain structures (e.g., the orbitofrontal cortex and cingulate gyrus) and language-related brain structures (e.g., the temporal lobe and the lingual gyrus).Discussion:These results suggested that faces are an effective source for the acquisition of words’ emotional connotations, and such acquired connotations can generate semantic and emotional congruency effects in sentential contexts.

“…In the present study, COPD patients showed increased CBF/DC ratio in the left LNG, which was driven by disproportionally attenuated CBF and DC. The LNG involves in encoding of complex images ( Machielsen et al, 2015 ), identification and recognition of words ( Mechelli et al, 2000 ). Supporting this, the LNG is functionally associated with decreased naming performance ( Deverdun et al, 2019 ) and visual processing ( Chee et al, 2009 ) and visual hallucination ( Goldman et al, 2014 ).…”

Purpose Cognitive impairment (CI) is very common in patients with chronic obstructive pulmonary disease (COPD). Cerebral structural and functional abnormalities have been reported in cognitively impaired patients with COPD, and the neurovascular coupling changes are rarely investigated. To address this issue, arterial spin labeling (ASL) and resting-state blood oxygenation level dependent (BOLD) fMRI techniques were used to determine whether any neurovascular changes in COPD patients. Methods Forty-five stable COPD patients and forty gender- and age-matched healthy controls were recruited. Furthermore, resting-state BOLD fMRI and ASL were acquired to calculate degree centrality (DC) and cerebral blood flow (CBF) respectively. The CBF-DC coupling and CBF/DC ratio were compared between the two groups. Results COPD patients showed abnormal CBF, DC and CBF/DC ratio in several regions. Moreover, lower CBF/DC ratio in the left lingual gyrus negatively correlated with naming scores, lower CBF/DC ratio in medial frontal cortex/temporal gyrus positively correlated with the Montreal Cognitive Assessment (MoCA), visuospatial/executive and delayed recall scores. Conclusion These findings may provide new potential insights into neuropathogenesis of cognition decline in stable COPD patients.

Purpose Mild cognitive impairment in chronic obstructive pulmonary disease (COPD) is receiving more and more attentions. Cerebral structural and functional abnormalities in COPD have been reported, the neurovascular coupling changes during resting state in COPD are rarely investigated. Our study was aimed to characterize neurovascular coupling changes in patients with COPD by using arterial spin labeling (ASL) and blood oxygenation level dependent (BOLD) techniques. Methods Forty-five stable COPD patients and forty gender- and age-matched healthy controls were recruited. And BOLD and ASL were acquired for calculating degree centrality (DC) and cerebral blood flow (CBF) respectively. The CBF-DC coupling and CBF/DC ratio were compared between the two groups. Results COPD patients showed abnormal CBF, DC and CBF/DC ratio in several regions. And lower CBF/DC ratio in left lingual gyrus negatively correlated with naming scores, lower CBF/DC ratio in medial frontal cortex/temporal gyrus positively correlated with MoCA, visuospatial/executive and delayed recall scores. Conclusion The abnormal neurovascular changes may be a possible neuropathological mechanism of mild cognitive impairment in stable COPD patients.
