It has been debated whether human visual working memory is limited by the number of items or precision with which they are represented. In research reported here, we show that can be flexibly and willfully controlled, but only if retained low. Electroencephalographic recordings revealed a neural marker for (contralateral delay activity, CDA) known to increase in amplitude was also affected were retained. However, enhanced increased CDA when These results both (willfully controlled) constrain...
Heating of gradient coils and passive shim components is a common cause instability in the B0 field, especially when intensive sequences are used. The aim study was to set benchmark for typical drift encountered during MR spectroscopy (MRS) assess need real-time field-frequency locking on MRI scanners by comparing field data from large number sites. A standardized protocol developed 80 participating sites using 99 3T 3 major vendors. Phantom water signals were acquired before after an EPI...
Abstract Interoception is one of the pivotal cognitive functions for mechanisms our body awareness, and malfunction interoceptive network thought to be associated with mental illness, including addiction. Within addictive disorders, substance‐based non‐substance‐based addictions are known hold dissociable reward systems. However, little about how awareness between these addiction sub‐types would differ. Subjective was assessed among patients alcohol use disorder ( n = 50) who were...
Interoceptive awareness (IA), the subjective and conscious perception of visceral physiological signals from body, has been associated with functions cortical subcortical neural systems involved in emotion control, mood anxiety disorders. We recently hypothesized that IA its contributions to mental health are realized by a brain interoception network (BIN) linking regions receive ascending interoceptive information brainstem, such as amygdala, insula anterior cingulate cortex (ACC). However,...
Human neuroimaging studies have implicated a number of brain regions in long-term memory formation. Foremost among these is ventrolateral prefrontal cortex. Here, we used double-pulse transcranial magnetic stimulation (TMS) to assess whether the contribution this part cortex crucial for laying down new memories and, if so, examine time course process. Healthy adult volunteers performed an incidental encoding task (living/nonliving judgments) on sequences words. In separate series, was either...
Electroencephalogram (EEG) analysis has garnered attention as a method for quantitatively decoding human emotions, and EEG amplitude values in specific frequency bands are typically used this purpose. However, brain states can fluctuate rapidly response to external stimuli, accounting temporal fluctuations could enhance the accuracy of emotion decoding. In paper, we investigate relationship between pleasant/unpleasant emotions by utilizing scale mixture model that assumes hierarchical...
Abstract Objective. Multiple facets of human emotion underlie diverse and sparse neural mechanisms. Among the many existing models emotion, two-dimensional circumplex model is an important theory. The use allows us to variable aspects emotion; however, such momentary expressions one’s internal mental state still lacks a notion third dimension time. Here, we report exploratory attempt build three-axis our sense anticipatory excitement, ‘Waku-Waku’ (in Japanese), in which people predictively...
Post-operative cognitive dysfunction (POCD) can be a serious surgical complication, and patients undergoing cardiac procedures are at particular risk for POCD. This study examined the effect of blocking neuroinflammation on behavioral neurogenic deficits produced in rat model cardiopulmonary bypass (CPB). Minocycline, drug with established anti-inflammatory activity, or saline was administered daily 30 days post-CPB. Treatment minocycline reduced number activated microglia/macrophages...
Abstract Trust attitude is a social personality trait linked with the estimation of others’ trustworthiness. Trusting others, however, can have substantial negative effects on mental health, such as development depression. Despite significant progress in understanding neurobiology trust, whether neuroanatomy trust depression vulnerability remains unknown. To investigate link between and vulnerability, we assessed depressive symptoms employed neuroimaging to acquire brain structure data...
Abstract Visual working memory (VWM) refers to our ability selectively maintain visual information in a mental representation. While cognitive limits of VWM greatly influence variety operations, it remains controversial whether the quantity or quality representations mind constrains VWM. Here, we examined behavior-to-brain anatomical relations as well brain activity anatomy associations with “neural” marker specific retention interval Our results consistently indicated that individuals who...
Data aggregation has been widely implemented as an infrastructure of data-driven systems. However, a centralized data model requires set strong trust assumptions to ensure security and privacy. In recent years, decentralized become realizable based on distributed ledger technology. Nevertheless, the lack appropriate mechanisms like identity management carries risks such impersonation unauthorized access. this paper, we propose novel framework by leveraging self-sovereign identity, emerging...
Interoception, our body's internal sensing of its physiological state, is central to emotional awareness. A key challenge lies in developing precise measurements tailored specific body regions and systems. We examined the connection between interoceptive sensibility as assessed by subjective report on awareness sensation maps, drawing insights from a sound evaluation task 508 healthy participants. To further elucidate missing link rumination trait awareness, we explored these bodily maps...
The complexity and high dimensionality of neuroimaging data pose problems for decoding information with machine learning (ML) models because the number features is often much larger than observations. Feature selection one crucial steps determining meaningful target in decoding; however, optimizing feature from such high-dimensional has been challenging using conventional ML models. Here, we introduce an efficient high-performance package incorporating a forward variable (FVS) algorithm...
It is well known that training of the texture discrimination task (TDT) leads to visual perceptual learning (VPL). Since VPL specific for location in which trained feature was presented, it has been suggested changes early cortex involved TDT. However, remains unclear whether associated with improvement higher cognitive functions including attention and also trained. In a meanwhile, proposed classified into three different abilities: 'alerting', 'orienting' 'executive control'. stimulus used...
