Although activation/deactivation of specific brain regions has been shown to be predictive successful memory encoding, the relationship between time-varying large-scale networks and fluctuations encoding performance remains unclear. Here, we investigated functional connectivity patterns across human in periods 30–40 s, which have recently implicated various cognitive functions. During magnetic resonance imaging, participants performed a task, their was assessed with subsequent surprise test....
Knowledge about one’s personality, the self-concept, shapes human experience. Social cognitive neuroscience has made strides addressing question of where and how self is represented in brain. The answer, however, remains elusive. We conducted two functional magnetic resonance imaging experiments (the second preregistered) with male female participants employing a self-reference task broad range attributes carrying out searchlight representational similarity analysis. importance to...
A distinct aspect of the sense fairness in humans is that we care not only about equality material rewards but also nonmaterial values. One such value opportunity to choose freely among many options, often regarded as a fundamental right economic freedom. In modern developed societies, equal opportunities work, living, and lifestyle are enforced by antidiscrimination laws. Despite widespread endorsement opportunity, no studies have explored how people assign it. We used functional magnetic...
Flexible adaptation to changing environments is a representative executive control function implicated in the frontoparietal network that requires appropriate extraction of goal-relevant information through perception external environment. It remains unclear, however, how flexibility achieved under situations where uncertain. To address this issue, current study examined neural mechanisms for task switching which task-relevant involved perceptual uncertainty. Twenty-eight human participants...
Past cognitive neuroscience research has demonstrated that thinking about both the self and other activate medial prefrontal cortex (mPFC), a central hub of default mode network. The mPFC is also implicated in processes, such as introspection autobiographical memory, rendering elusive its exact role during self. Specifically, it unclear whether same process explains common involvement or distinct processes are responsible for activation overlap. In this preregistered functional magnetic...
Previous studies showed that interindividual variations in mood state are associated with prefrontal cortex (PFC) activity. In this study, we focused on the depressed-mood under natural circumstances and examined relationship between within-individual changes over time PFC We used optical topography (OT), a functional imaging technique based near-infrared spectroscopy, to measure activity for each participant three experimental sessions repeated at 2-week intervals. session, participants...
Atypical sensory responses and seeking behaviors constitute the core symptoms of autism spectrum condition (ASC). There are possible links between atypical profiles attentional challenges in ASC. Due to paucity studies adults, nature their associations with autistic adults remain elusive. Here, we investigated sustained attention performance its 28 adult males 23 typically developing controls (TDCs). A gradual-onset continuous task Adolescent/Adult Sensory Profile were employed assess...
Abstract Autobiographic remembering often involves types of constructive processes for psychological experiences and hypothetical scenarios past events. Previous research revealed a range phenomenological functional characteristics associated with recalls episodes high autobiographical significance. However, neural bases such their association memory construction remain unclear. In this magnetic resonance imaging study, we collected from 28 young adults extensive metrics related to We then...
Increasing evidence suggests that psychiatric disorders are linked to alterations in the mesocorticolimbic dopamine-related circuits. However, common and disease-specific remain be examined schizophrenia (SCZ), major depressive disorder (MDD), autism spectrum (ASD). Thus, this study aimed examine features related
The neural mechanisms underlying visual perceptual learning (VPL) have typically been studied by examining changes in task-related brain activation after training. However, the relationship between post-task "offline" processes and VPL remains unclear. present study examined this question obtaining resting-state functional magnetic resonance imaging (fMRI) scans of human brains before a task-fMRI session involving During session, participants performed motion coherence discrimination task...
Self-control allows humans the patience necessary to maximize reward attainment in future. Yet it remains elusive when and how preference self-controlled choice is formed. We measured brain activity while female male performed an intertemporal task which they first received delayed real liquid rewards (forced-choice trial), then made a between options based on experiences (free-choice trial). found that, subjects were awaiting upcoming forced-choice trial, anterior prefrontal cortex (aPFC)...
Adaptation to changing environments involves the appropriate extraction of environmental information achieve a behavioral goal. It remains unclear how flexibility is guided under situations where relevant behavior ambiguous. Using functional brain mapping machine learning decoders and directional connectivity, we show that brain-wide reversible neural signaling underpins task encoding in ambiguously environments. When cued during shifting, coding attenuated distributed cortical regions, but...
In real life, humans make decisions by taking into account multiple independent factors, such as delay and probability. Cognitive psychology suggests that cognitive control mechanisms play a key role when facing complex task conditions. However, in value-based decision-making, it still remains unclear to what extent become essential the condition is complex. this study, we investigated decision-making behaviors underlying neural using multifactor gambling where participants simultaneously...
Social norms regulate behavior, and changes in have a great impact on society. In most modern societies, change through interpersonal communication persuasive messages found media. Here, we examined the neural basis of persuasion-induced attitude toward away from using fMRI. We measured brain activity while human participants were exposed to directed specific norms. Persuasion social specifically activated set regions including temporal poles, temporo-parietal junction, medial prefrontal...
Recent advances in technologies for neuroscientific research enable us to investigate the neurobiological substrates of human ethical sense. This article introduces several findings "the brain science ethics" obtained through brain-observation and brain-manipulation approaches. Studies over past decade have revealed that structures associated with emotion processing ability understand minds others play key roles We also discuss current limitations studying mechanisms ethics: Although true...
Psychological research on human motivation repeatedly observed that approach goals (i.e., to attain success) increase task enjoyment and intrinsic more strongly than avoidance avoid failure). The present study sought address how the reward network in brain-including striatum ventromedial prefrontal cortex-is involved when individuals engage same with a focus or goals. Participants reported stronger positive emotions they focused goals, but anxiety disappointment fMRI analyses revealed brain...
