Recent work has focussed on how patterns of functional change within the temporal lobe relate to whole-brain dimensions intrinsic connectivity variation (Margulies et al., 2016). We examined two such 'connectivity gradients' reflecting separation (i) unimodal versus heteromodal and (ii) visual auditory-motor cortex, examining visually presented verbal associative feature judgments, plus picture-based context emotion generation. Functional responses along first dimension sometimes showed...

We compared the carbon emissions of preprocessing and statistical analysis fMRI data in software packages FSL, SPM, fMRIPrep. Carbon for fMRIPrep were 30x larger than those 23x SPM. also scientific performance each package, reflected by sensitivity to activation. Overall, demonstrated slightly superior both FSL with outperforming However, this pattern varied brain region. Researchers analysing can use information inform their choice considering footprint processing alongside usability...

Abstract Patients with semantic aphasia have impaired control of retrieval, often accompanied by executive dysfunction following left hemisphere stroke. Many but not all these patients damage to the inferior frontal gyrus, important for and cognitive control. Yet networks are highly distributed, including posterior as well anterior components. Accordingly, might only reflect local also white matter structural functional disconnection. Here, we characterise lesions predicted patterns...

Abstract Given that scientific practices contribute to the climate crisis, scientists should reflect on planetary impact of their work. Research computing can have a substantial carbon footprint in cases where researchers employ computationally expensive processes with large amounts data. Analysis human neuroimaging data, such as Magnetic Resonance Imaging brain scans, is one case. Here, we consider ten ways which those who conduct research reduce computing, by making adjustments studies are...

Adaptive behavior relies both on specific rules that vary across situations and stable long-term knowledge gained from experience. The frontoparietal control network (FPCN) is implicated in the brain's ability to balance these different influences action. Here, we investigate how topographical organization of cortex supports behavioral flexibility within FPCN. Functional properties this might reflect its juxtaposition between dorsal attention (DAN) default mode (DMN), two large-scale systems...

Abstract Understanding how human cognition flexibly supports distinct forms of behavior is a key goal neuroscience. Adaptive relies on context-specific rules that vary across situations, as well stable knowledge gained from experience. However, the mechanisms allow these influences to be appropriately balanced remain elusive. Here, we show this cognitive flexibility partly supported by topographical organization cortex. The frontoparietal control network (FPCN) located between regions...

The default mode network (DMN) lies towards the heteromodal end of principal gradient intrinsic connectivity, maximally separated from sensory-motor cortex. It supports memory-based cognition, including capacity to retrieve conceptual and evaluative information sensory inputs, generate meaningful states internally; however, functional organisation DMN that can support these distinct modes retrieval remains unclear. We used fMRI examine whether activation within subsystems differed as a...

Abstract Computationally expensive data processing in neuroimaging research places demands on energy consumption—and the resulting carbon emissions contribute to climate crisis. We measured footprint of functional magnetic resonance imaging (fMRI) preprocessing tool fMRIPrep, testing effect varying parameters estimated and performance. Performance was quantified using (a) statistical individual‐level task activation regions interest (b) mean smoothness preprocessed data. Eight variants...

Eye-tracking research on social attention in infants and toddlers has included heterogeneous stimuli analysis techniques. This allows measurement of looking to inner facial features under diverse conditions but restricts across-study comparisons. Eye–mouth index (EMI) is a measure relative preference for the eyes or mouth, independent time spent attending face. The current study assessed whether EMI was more robust differences stimulus type than percent dwell (PDT) toward eyes, Participants...

Recent insights show that increased motivation can benefit executive control, but this effect has not been explored in relation to semantic cognition. Patients with deficits of controlled retrieval the context aphasia (SA) after stroke may from approach since 'semantic control' is considered an process. Deficits domain are partially distinct domain-general cognitive control. We assessed both extrinsic and intrinsic healthy controls SA patients. Experiment 1 manipulated reward using high or...

Computationally expensive data processing in neuroimaging research places demands on energy consumption - the resulting carbon emissions contribute to climate crisis. We measured footprint of fMRI preprocessing tool fMRIPrep, testing effect varying parameters estimated and performance. Performance was quantified using (a) statistical individual-level task activation regions interest (b) mean smoothness preprocessed data. Eight variants fMRIPrep were run with 257 participants who had...

The brain is a dynamic system where complex behaviours emerge from interactions across distributed regions. Accurately linking function to cognition requires tools that are sensitive these dynamics. We introduce novel technique - Feature Similarity (FS) capture intricate interaction patterns between systems. Our results show FS can functional organisation: regions within the same network have greater compared those in different networks, and also identifies principal gradient spans unimodal...

According to a constructionist model of emotion, conceptual knowledge plays foundational role in emotion perception; reduced availability relevant should therefore impair perception. Conceptual deficits can follow both degradation semantic (e.g., ‘storage’ dementia) and deregulation retrieval ‘access’ aphasia). While recognition are known accompany degraded knowledge, less is about the impact access deficits. Here, we examined perception categorization tasks patients with aphasia, who have...

Abstract The hub‐and‐spoke model of semantic cognition proposes that conceptual representations in a heteromodal ‘hub’ interact with and emerge from modality‐specific features or ‘spokes’, including valence (whether concept is positive negative), along visual auditory features. As result, congruency might facilitate our ability to link words conceptually. Semantic relatedness may similarly affect explicit judgements about valence. Moreover, conflict between meaning recruit control processes....
