Significance What are the origins of resting-state functional connectivity patterns? One dominating view is that they index ongoing cognitive processes. However, this conclusion in conflict with studies showing long-range persists after loss consciousness, possibly reflecting structural maps. In work we respond to question fact both sources have a clear and separable contribution patterns. We show under anesthesia, configurations low information capacity lack negative correlations....

In recent years, numerous electrophysiological signatures of consciousness have been proposed. Here, we perform a systematic analysis these electroencephalography markers by quantifying their efficiency in differentiating patients vegetative state from those minimally conscious or state. Capitalizing on review previous experiments and current theories, identify series measures that can be organized into four dimensions: (i) event-related potentials versus ongoing activity; (ii) local...

The human brain is organized in functional modules. Such an organization presents a basic conundrum: modules ought to be sufficiently independent guarantee specialization and connected bind multiple processors for efficient information transfer. It commonly accepted that small-world architecture of short lengths large local clustering may solve this problem. However, there intrinsic tension between shortcuts generating small-worlds the persistence modularity; global property unrelated...

We examined the functional organization of cerebral activity in 3-month-old infants when they were listening to their mother language. Short sentences presented a slow event-related MRI paradigm. then parsed infant's network perisylvian responsive regions into functionally distinct based on speed activation and sensitivity sentence repetition. An adult-like structure response delays was observed along superior temporal regions, suggesting hierarchical processing scheme. The fastest responses...

During language processing, humans form complex embedded representations from sequential inputs. Here, we ask whether a "geometrical language" with recursive embedding also underlies the human ability to encode sequences of spatial locations. We introduce novel paradigm in which subjects are exposed sequence locations on an octagon, and asked predict future The vary complexity according well-defined comprising elementary primitives rules. A detailed analysis error patterns indicates that...

We present results from a “corruption game” (a dictator game modified so that recipients can take side payment in exchange for accepting reduction the overall size of pie). Dictators (silently) treated to be able more recipient's tokens, took them. They were also likely believe had accepted payments, even if there was prize accuracy. The favor hypothesis people avoid altruistic actions by distorting beliefs about others' altruism. (JEL C72, D63, D64, D83)

Recursive social decision-making requires the use of flexible, context-sensitive long-term strategies for negotiation. To succeed in bargaining, participants' own perspectives must be dynamically integrated with those interactors to maximize self-benefits and adapt other's preferences, respectively. This is a prerequisite develop successful self-other integration strategy. While such form strategic interaction critical decision-making, little known about its neurocognitive correlates. bridge...

Interoception, the perception of our body internal signals, plays a key role in maintaining homeostasis and guiding behavior. Sometimes, we become aware signals use them planning strategic thinking. Here, show behavioral neural dissociations between learning to follow one's own heartbeat metacognitive awareness performance, heartbeat-tapping task performed before after auditory feedback. The electroencephalography amplitude heartbeat-evoked potential interoceptive learners, that is,...

Depersonalization-Derealization Disorder (DD) typically manifests as a disruption of body self-awareness. Interoception −defined the cognitive processing signals− has been extensively considered key for In consequence, purpose this study was to investigate whether there are systematic differences in interoception between patient with DD and controls that might explain disembodiment symptoms suffered disease. To assess interoception, we utilized heartbeat detection task measures functional...

Significance Executive functions (EF) imply processes critical for purposeful, goal-directed behavior. In children, evidence derived from laboratory measures indicates that training can improve EF. However, this hypothesis has never been explicitly examined based on real-world measures, especially of educational achievement. Here, we investigate whether a set computerized games might yield transfer low-socioeconomic status otherwise typically developing 6-y-olds in an intervention deployed...

Abstract Background Interoception refers to the conscious perception of body signals. Mindfulness is a meditation practice that encourages individuals focus on their internal experiences such as bodily sensations, thoughts, and emotions. In this study, we selected behavioral measure interoceptive sensitivity (heartbeat detection task, HBD) compare effect among long term practitioners (LTP), short meditators (STM, subjects completed Mindfulness-Based Stress Reduction (MBSR) program) controls...

Although it has been shown that adults with attention-deficit hyperactivity disorder (ADHD) have impaired social cognition, no previous study reported the brain correlates of face valence processing. This looked for behavioral, neuropsychological, and electrophysiological markers emotion processing faces (N170) in adult ADHD compared to controls matched by age, gender, educational level, handedness. We designed an event-related potential (ERP) based on a dual task (DVT), which words were...
