The default mode network supports a variety of mental operations such as semantic processing, episodic memory retrieval, time travel and mind-wandering, yet the commonalities between these functions remains unclear. One possibility is that this system cognition independent immediate environment; alternatively or additionally, it might support higher-order conceptual representations draw together multiple features. We tested accounts using novel paradigm separately manipulated availability...
Regions of transmodal cortex, in particular the default mode network (DMN), have historically been argued to serve functions unrelated task performance, part because associations with naturally occurring periods off-task thought. In contrast, contemporary views DMN suggest it plays an integrative role cognition that emerges from its location at top a cortical hierarchy and relative isolation systems directly involved perception action. The combination these topographical features may allow...
The 21st century marks the emergence of "big data" with a rapid increase in availability datasets multiple measurements. In neuroscience, brain-imaging are more commonly accompanied by dozens or hundreds phenotypic subject descriptors on behavioral, neural, and genomic level. complexity such repositories offer new opportunities pose challenges for systems neuroscience. Canonical correlation analysis (CCA) is prototypical family methods that useful identifying links between variable sets from...
Abstract When environments lack compelling goals, humans often let their minds wander to thoughts with greater personal relevance; however, we currently do not understand how this context-dependent prioritisation process operates. Dorsolateral prefrontal cortex (DLPFC) maintains goal representations in a manner. Here, show region is involved prioritising off-task thought an analogous way. In whole brain analysis established that neural activity DLPFC high both when ‘on-task’ under demanding...
Movie-watching is a central aspect of our lives and an important paradigm for understanding the brain mechanisms behind cognition as it occurs in daily life. Contemporary views ongoing thought argue that ability to make sense events ‘here now’ depend on neural processing incoming sensory information by auditory visual cortex, which are kept check systems association cortex. However, we currently lack how patterns thoughts map onto different when watch film, partly because methods sampling...
When not engaged in the moment, we often spontaneously represent people, places and events that are present environment. Although this capacity has been linked to default mode network (DMN), it remains unclear how interactions between nodes of give rise particular mental experiences during spontaneous thought. One hypothesis is core DMN integrates information from medial lateral temporal lobe memory systems, which different aspects knowledge. Individual differences connectivity regions would...
Experiences such as mind-wandering illustrate that cognition is not always tethered to events in the here-and-now. Although converging evidence emphasises default mode network (DMN) mind-wandering, its precise contribution remains unclear. The DMN comprises cortical regions are maximally distant from primary sensory and motor cortex, a topological location may support stimulus-independence of mind-wandering. functionally heterogeneous, comprising engaged by memory, social planning; processes...
The tendency for the mind to wander concerns other than task at hand is a fundamental feature of human cognition, yet consequences variations in its experiential content psychological functioning are not well understood. Here, we adopted multivariate pattern analysis simultaneously decompose experience-sampling data and neural functional-connectivity data, which revealed dimensions that describe individual variation self-reported experience default-mode-network connectivity. We identified...
Contemporary accounts of ongoing thought recognise it as a heterogeneous and multidimensional construct, varying in both form content. An emerging body evidence demonstrates that distinct types experience are associated with unique neurocognitive profiles, can be described at the whole-brain level interactions between multiple large-scale networks. The current study sought to explore possibility functional connectivity patterns rest may meaningfully related occurred over this period....
The human mind is equally fluent in thoughts that involve self-generated mental content as it with information the immediate environment. Previous research has shown neural systems linked to executive control (i.e. dorsolateral prefrontal cortex) are recruited when perceptual and balanced line demands imposed by external world. Contemporary theories (Smallwood Schooler, 2015) assume differentiable processes important for than its regulation. current study used functional magnetic resonance...
Abstract Cognition is dynamic and involves both the maintenance of transitions between neurocognitive states. While recent research has identified some neural systems involved in sustaining task states, it less well understood how intrinsic influences on cognition emerge over time. The current study uses fMRI Multi-Dimensional Experience Sampling (MDES) to chart changes time from moments when external attention was established. We found that passage associated with brain regions decreasing...
Psychological states influence our happiness and productivity; however, estimates of their impact have historically been assumed to be limited by the accuracy with which introspection can quantify them. Over last two decades, studies shown that introspective descriptions psychological correlate objective indicators cognition, including task performance metrics brain function, using techniques like functional magnetic resonance imaging (fMRI). Such evidence suggests it may possible mapping...
Cognitive neuroscience has gained insight into covert states using experience sampling. Traditionally, this approach focused on off-task states. However, task-relevant are also maintained via processes. Our study examined whether sampling can provide insights goal-relevant that support task performance. To address question, we developed a neural state space, dimensions of brain function variation, allows correlates overt and to be in common analytic space. We use describe activity during...
Reducing contributions from non-neuronal sources is a crucial step in functional magnetic resonance imaging (fMRI) connectivity analyses. Many viable strategies for denoising fMRI are used the literature, and practitioners rely on benchmarks guidance selection of an appropriate choice their study. However, software ever-evolving field, can quickly become obsolete as techniques or implementations change. In this work, we present benchmark featuring range strategies, datasets evaluation...
Abstract Features of ongoing experience are common across individuals and cultures. However, certain people express specific patterns thought to a greater extent than others. Contemporary psychological theory assumes that individual differences in occur because different types depend on the expression neurocognitive processes. Consequently, variation underlying architecture is hypothesised determine ease with which generated or maintained. Our study (N = 178) tested this hypothesis using...
Trying to focus on a piece of text and keep unrelated thoughts at bay can be surprisingly futile experience. The current study explored the effects different instructions participants' capacity control their mind-wandering maximize reading comprehension, while reading. Participants were instructed (a) enhance what was read (external) or (b) meta-awareness (internal). To understand when these strategies important, we induced state self-focus in half our participants beginning experiment....
